FPF2180/82/83/84/86/87 Full Function Load Switch with Reverse Current Blocking Features General Description 1.8 to 5.5V Input Voltage Range The FPF2180/82/83/84/86/87 is a series of load switches which provides full protection to systems and loads which may encounter large current conditions. These devices contain a 55m current-limited P-channel MOSFET which can operate over an input voltage range of 1.8-5.5V. Internally, current is prevented from flowing when the MOSFET is off and the output voltage is higher than the input voltage. Switch control is by a logic input (ON) capable of interfacing directly with low voltage control signals. Each part contains thermal shutdown protection which shuts off the switch to prevent damage to the part when a continuous over-current condition causes excessive heating. Controlled Turn-On 200mA and 400mA Current Limit Options Undervoltage Lockout Thermal Shutdown <2 A Shutdown Current Auto Restart Fast Current limit Response Time 5 s to Moderate Over Currents 30ns to Hard Shorts When the switch current reaches the current limit, the part operates in a constant-current mode to prohibit excessive currents from causing damage. For the FPF2180/82/84/86, if the constant current condition still persists after 30ms, the part will shut off the switch and pull the fault signal pin (FLAGB) low. The FPF2180/84 have an auto-restart feature which will turn the switch on again after 450ms if the ON pin is still active. The FPF2182/86 do not have this auto-restart feature so the switch will remain off until the ON pin is cycled. For the FPF2183/87, a current limit condition will immediately pull the fault signal pin low and the part will remain in the constant-current mode until the switch current falls below the current limit. The minimum current limit is 200mA for the FPF2180/82/83 while that for the FPF2184/86/87 is 400mA.

Switch is turned on into a large output capacitor 1.Short circuit detection. When the output voltage is below VSCTH=1.1V, the current limit value is set at 62.5% of the current limit value. 2.

Output current is below the current limit value FPF2180/82/83/84/86/87 Rev. F 9 www.fairchildsemi.com drops below VSCTH, short circuit detection threshold voltage, the current limit value re-conditioned and short circuit current limit value is decreased to 62.5% of the current limit value. This keeps the power dissipation of the part below a certain limit even at dead short conditions at 5.5V input voltage. The VSCTH value is set to be 1V. At around 1.1V of output voltage the switch is removed from short circuit current limiting mode and the current limit is set to the current limit value. The FPF2180/82/83/84/86/87 are current limited switches that protect systems and loads which can be damaged or disrupted by the application of high currents. The core of each device is a 55m P-channel MOSFET and a controller capable of functioning over a wide input operating range of 1.8-5.5V. The controller protects against system malfunctions through current limiting, under-voltage lockout and thermal shutdown. The current limit is preset for either 200mA or 400mA. Under-Voltage Lockout The under-voltage lockout turns-off the switch if the input voltage drops below the under-voltage lockout threshold. With the ON pin active the input voltage rising above the under-voltage lockout threshold will cause a controlled turn-on of the switch which limits current over-shoots. On/Off Control The ON pin controls the state of the switch. Activating ON continuously holds the switch in the on state so long as there is no under-voltage on VIN or a junction temperature in excess of 140C. ON is active HI and has a low threshold making it capable of interfacing with low voltage signals. In addition, excessive currents will cause the switch to turn off for FPF2180/ 82 and FPF2184/86. The FPF2180/84 have an Auto-Restart feature which will automatically turn the switch on again after 450ms. For the FPF2182/86, the ON pin must be toggled to turn-on the switch again. The FPF2183/87 do not turn off in response to a over current condition but instead remain operating in a constant current mode so long as ON is active and the thermal shutdown or under-voltage lockout have not activated. Thermal Shutdown The thermal shutdown protects the die from internally or externally generated excessive temperatures. During an over-temperature condition the FLAGB is activated and the switch is turned-off. The switch automatically turns-on again if temperature of the die drops below the threshold temperature. Reverse Current Blocking The entire FPF2180/82/83/84/86/87 family has a Reverse Current Blocking feature that protects input source against current flow from output to input. For a standard USB power design, this is an important feature which protects the USB host from being damaged due to reverse current flow on VBUS. Fault Reporting Upon the detection of an over-current, an input under-voltage, or an over-temperature condition, the FLAGB signals the fault mode by activating LO. For the FPF2180/82/84/86, the FLAGB goes LO at the end of the blanking time while FLAGB goes LO immediately for the FPF2183/87. FLAGB remains LO through the Auto-Restart Time for the FPF2180/84. For the FPF2182/86, FLAGB is latched LO and ON must be toggled to release it. With the FPF2183/87, FLAGB is LO during the faults and immediately returns HI at the end of the fault condition. FLAGB is an open-drain MOSFET which requires a pull-up resistor between VIN and FLAGB. During shutdown, the pull-down on FLAGB is disabled to reduce current draw from the supply. When the load switch is OFF, no current flows from the output to the input. If the switch is turned on and the output voltage is greater than input voltage this feature is activated and turns off the switch. This will prevent any current flow from output to input. The reverse current blocking feature will be deactivated if the VOUT - VIN is smaller than a typically 50mV threshold. During this time some current (50mV/RON) will flow from the output to input until input voltage become greater than output voltage. The FLAGB operation is independent of the Reverse Current blocking and will not report a fault condition if this feature is activated. Current Limiting The current limit guarantees that the current through the switch doesn't exceed a maximum value while not limiting at less than a minimum value. For the FPF2180/82/83 the minimum current is 200mA and the maximum current is 400mA and for the FPF2184/86/87 the minimum current is 400mA and the maximum current is 800mA. The FPF2180/82/84/86 have a blanking time of 30ms, nominally, during which the switch will act as a constant current source. At the end of the blanking time, the switch will be turned-off and the FLAGB pin will activate to indicate that current limiting has occurred. The FPF2183/87 have no current limit blanking period so immediately upon a current limit condition FLAGB is activated. These parts will remain in a constant current state until the ON pin is deactivated or the thermal shutdown turns-off the switch.

When using the FPF2182/86, attention must be given to the manual resetting of the part. Continuously resetting the part at a high duty cycle when a short on the output is present can cause the temperature of the part to increase. The junction temperature will only be allowed to increase to the thermal shutdown threshold. Once this temperature has been reached, toggling ON will not turn-on the switch until the junction temperature drops. For the FPF2180/84, a short on the output will cause the part to operate in a constant current state dissipating a worst case power as calculated in (3) until the thermal shutdown activates. It will then cycle in and out of thermal shutdown so long as the ON pin is active and the short is present. Input Capacitor To limit the voltage drop on the input supply caused by transient in-rush currents when the switch turns-on into a discharged load capacitor or a short-circuit, a capacitor needs to be placed between VIN and GND. A 0.1 F ceramic capacitor, CIN, placed close to the pins is usually sufficient. Higher values of CIN can be used to further reduce the voltage drop. Output Capacitor A 0.1uF capacitor COUT, should be placed between VOUT and GND. This capacitor will prevent parasitic board inductances from forcing VOUT below GND when the switch turns-off. For the FPF2180/82/84/86, the total output capacitance needs to be kept below a maximum value, COUT(max), to prevent the part from registering an over-current condition and turning-off the switch. The maximum output capacitance can be determined from the following formula, COUT(max) = ILIM(max) x tBLANK(min) Board Layout For best performance, all traces should be as short as possible. To be most effective, the input and output capacitors should be placed close to the device to minimize the effects that parasitic trace inductances may have on normal and short-circuit operation. Using wide traces for VIN, VOUT and GND will help minimize parasitic electrical effects along with minimizing the case to ambient thermal impedance. (1) VIN Power Dissipation During normal operation as a switch, the power dissipation is small and has little effect on the operating temperature of the part. The parts with the higher current limits will dissipate the most power and that will only be, P = (ILIM)2 x RON = (0.8)2 x 0.055 = 35.2mW (2) If the part goes into current limit the maximum power dissipation will occur when the output is shorted to ground. For the FPF2180/84, the power dissipation will scale by the Auto-Restart Time, tRSTRT, and the Over Current Blanking Time, tBLANK, so that the maximum power dissipated is, P(max) = = tBLANK tBLANK + tRSTRT x VIN(max) x ILIM(max) 30 x 5.5 x 0.8 = 275mW 30 + 450 FPF2180/82/83/84/86/87 Rev.

No battery is loaded to the output Power Good Sequential Startup using Power Good FPF218X family has a "Power Good" feature. PGOOD pin is an open-drain MOSFET which asserts high when the output voltage reaches 90% of the input voltage. The power good pin can be connected to another load switch's enable pin to implement sequential startup. PGOOD pin asserts low when the load switch is OFF. This feature allows driving a subsequent circuit. The diagram illustrates power good function in sequential startup. As the VOUT1 of the first load switch starts to ramp to the 90% of its input voltage the second switch remains in OFF state. Whereas the VOUT1 passes the 90% threshold, power good signal becomes active and asserts high. This signal will turn on the second load switch and VOUT2 will start to increase. The total startup time may vary according to the difference between supply voltages that are used in the application. PGOOD pin requires an external pull up resistor that is connected to the output voltage when there is no battery in the load side and the logic level of the subsequent controller permits. This would give logic levels similar to a CMOS output stage for PGOOD, while still keeping the option to tie the pull-up to a different supply voltage. A 100K is recommended to be used as pull up resistor. The PGOOD pin status is independent of the ON pin position. This mean that PGOOD pin stays low when the load switch is OFF. If the Power Good feature is not used in the application the pin can be connected directly to GND. FPF2180/82/83/84/86/87 Rev.
