DATA SHEET AAT4620 PCMCIA Current Limit Interface and Capacitor Charger General Description Features The AAT4620 SmartSwitch is a current limited P-channel MOSFET power switch designed for high-side loadswitching applications in PCMCIA GSM/GPRS/3G modem cards. Used in conjunction with a super capacitor, the AAT4620 will ensure that the power ratings of the PCMCIA host are not exceeded at any time. Featuring two independent, programmable current limits and a power loop, the AAT4620 can ensure that the super capacitor can be charged without exceeding PCMCIA specifications. The current limit is set by two external resistors allowing a 10% current limit accuracy over the normal operating temperature range. The switch can be controlled from either of the two enable inputs and in the off condition will block currents in both directions. The AAT4620 also incorporates a System READY function which can advise the system that the super capacitor is fully charged and ready for use. Adjustable hysteresis is provided with the addition of an external resistor. The quiescent supply current is typically a low 40A. In shutdown mode, the supply current decreases to less than 1A. * VIN Range: 3.0V to 5.5V * Dual Independent Current Limits 100mA to 1200mA 10% Current Accuracy 20C Temperature Band * Reverse Current Blocking Protection * Power Loop * Low Quiescent Current 40A Typical 1.0A Max with Switch Off * 65m Typical RDS(ON) at 3V * Only 1.4V Needed for Enable Control Pin * System READY Output with Externally Programmable Hysteresis * Under-Voltage Lockout * Temperature Range: -40C to 85C * 12-Pin TSOPJW Package The AAT4620 is available in a thermally enhanced, Pb-free, 12-pin TSOPJW package and is specified over the -40C to 85C temperature range.

The current limit control is combined with an over temperature thermal limit and power loop circuit to provide a comprehensive system to protect the load switch and its supply from load conditions which exceed the supply specifications. The AAT4620 has been designed specifically to provide the interface between a PCMCIA host and PCMCIA card where a super capacitor has been used ISETL ISETU RHYS to "average out" high pulse currents which would otherwise exceed the PCMCIA/ Express Card power specifications. e.g. GSM/ GPRS modem cards, where pulse currents during transmit signals can exceed the 1A maximum specification (1.3A in the case of Express Card). The current limit and over temperature circuits act independently. The device current limit is activated when the output load current exceeds an internal threshold level. There are two internal current limits which are enabled independently. The current limit threshold in each case is determined by external resistors connected between the two SET pins and ground. The minimum current limit Skyworks Solutions, Inc. * Phone [781] 376-3000 * Fax [781] 376-3100 * sales@skyworksinc.com * www.skyworksinc.com 201943A * Skyworks Proprietary Information * Products and Product Information are Subject to Change Without Notice. * May 15, 2012 9 DATA SHEET AAT4620 PCMCIA Current Limit Interface and Capacitor Charger threshold is specified by ILIM(MIN). If the load condition maintains the device in current limit and the chip temperature reaches a critical point, then an internal power loop will reduce the current to a safe level. Connecting ISETU to ground disables the current limit protection allowing a low impedance path to the host VCC. The load switch is turned off by applying a logic high level to both of the EN pins. When both EN IL and EN IU are selected ISETU will be selected. The EN function has logic level thresholds that allow the AAT4620 to be TTL compatible and may also be controlled by 2.5V to 5.0V CMOS circuits. The voltage level applied to the EN pins should not exceed the input supply level present on the VCC pin. The AAT4620 typically consumes 40A when operating, when off, the device draws less then 1A. In the off state, current is prevented from flowing between the input and output. Under-voltage lockout circuitry ensures that the VCC supply is high enough for correct operation of the IC. Also included is a System Ready function which will be activated when the capacitor voltage is charged and the load is permitted to take current. For automatic functionality, this pin can be directly connected to the EN IU pin. An external resistor is provided to add hysteresis to this function. Application Information ISETU and ISETL Current Limit Set The AAT4620 current limit is set at two different levels. Resistors from ISETL and ISETU set the lower and upper current limit levels respectively. The ISETL and ISETU nodes operate within a window of 0.75V to 1.5V for resistor values ranging from 93.75 to 1.5M. Resistor values outside this range are not recommended. The ISETL and ISETU source current varies with the resistor value used according to Table 1. To determine the resulting current limit multiply the RSETU or RSETL node voltage times the gain in Table 1. Note that the voltage at the node varies from 0.75V to 1.5V and the current limit gain varies depending on the resistor value used. VISET = RSET * IISET = 0.75V to 1.5V If the set pin is open circuit or allowed to exceed 2V, all power devices are disabled and the input is disconnected from the output. Shorting the set pin to GND enables all power devices and shorts the VCC to the output pin with no current limit. To activate the upper current level (RSETU) pull EN IU low. To activate the lower current level (RSETL) pull EN IL low. If both EN IU and EN IL are pulled low the EN IU current limit level (RSETU) will be selected.

If die temperature is less than 100C, it increases the load current in increments of 1/32 of the current limit set point until the set current limit point is reached or the die temperature exceeds 100C. 1.2 ILOAD Limit (A) 1.0 0.8 0.6 0.4 0.2 0.0 0.10 0.30 0.50 0.70 0.90 1.10 1.30 1.50 RSETU and RSETL (M ) Figure 1: Calculated Current Limit RSET Characteristic. System Ready Hysteresis (RHYS) and System Ready (RDY) In internal comparator senses the output voltage and delivers a ready signal to the external micro controller when the output voltage reaches 98% of the final value (VCC). The comparator hysteresis is programmed by a resistor from the RHYS pin to ground. The RHYS voltage determines the hysteresis voltage and is equal to the RHYS source current (1A) times the RHYS resistance. VHYST = RHYS * 1A = 200k * 1A = 0.2V The system ready pin (RDY) is an open drain output that switches low when the output voltage reaches 98% of the input voltage. It requires an external pull up resistor tied to the input voltage with a typical value of 100k. Power Loop The AAT4620 power loop limits the load current in the event that the device power dissipation becomes excessive. The AAT4620 power loop regulates the die temperature to 100C, decreasing the load current in increments of 1/32 of the current limit set point when the die temperature reaches 100C. When the die temperature The delay time between die temperature measurements varies depending on the load current limit set point. The delay ranges from 1ms for a 75mA current limit set point to 8ms for a 1.5A current limit set point. For the condition where there is no current limit set point (shorting RSETU or RSETL to ground) the soft start increments the current limit is 1/32 steps of 1.2A until the current reaches 1.2A, at which point the power MOSFET turns on fully. At this point, the current is limited by the RDS(ON) of the power MOSFET and other series resistance. The Power Loop and Over-Temperature Loop then takes control to limit the current until the output voltage has fully charged. Over-Temperature Protection If the die temperature rate of rise is fast enough to exceed the power loop regulated temperature, overtemperature shutdown disables the device. The overtemperature threshold is 145C. After over-temperature shutdown, soft start is initiated once the die temperature drops to 130C. Short Circuit Protection The series pass power MOSFET turns off completely after the output has charged to within 18mV of the input voltage. This protects the device in the event of a short circuit applied to the output. Applying a short circuit or heavy load to the output initiates the digital soft start where the current ramps from zero to the final programmed value. The power loop will be activated once the digital soft start begins. Under-Voltage Shutdown Under-voltage lockout enables the device at 2.7V typical with 100mV of hysteresis. The maximum UVLO level is 3.0V.
