Is Now Part of To learn more about ON Semiconductor, please visit our website at www.onsemi.com Please note: As part of the Fairchild Semiconductor integration, some of the Fairchild orderable part numbers will need to change in order to meet ON Semiconductor's system requirements. Since the ON Semiconductor product management systems do not have the ability to manage part nomenclature that utilizes an underscore (_), the underscore (_) in the Fairchild part numbers will be changed to a dash (-). This document may contain device numbers with an underscore (_). Please check the ON Semiconductor website to verify the updated device numbers.

FPF3040 IntelliMAXTM 18 V-Rated Dual Input Single Output Power-Source-Selector Switch Description Features Dual-Input, Single-Output Load Switch Input Supply Operating Range: - 4~10.5 V at VIN - 4~6.5 V at VBUS Typical RON: 95 m at VIN=5 V 70 m at VBUS=5 V Bi-Directional Switch for VIN and VBUS Slew Rate Controlled: - 50 s at VIN for < 4.7 F COUT 90 s at VBUS for < 4.7 F COUT Maximum ISW: 2 A Per Channel ESD Protected: Break-Before-Make Transition The FPF3040 is a 18 V-rated Dual-Input Single-Output (DISO) load switch consisting of two channels of slewrate-controlled, low-on-resistance, N-channel MOSFET switches with protection features. The slew-ratecontrolled turn-on characteristic prevents inrush current and the resulting excessive voltage droop on the input power rails. The input voltage range operates from 4 V to 6.5 V at VBUS and from 4 V to 10.5 V at VIN to align with the needs of low-voltage portable device power rails. VIN and VBUS have the over-voltage protection functionality of typical 12 V and 7.5 V, respectively, to avoid unwanted damage to system. VIN and VBUS bi-directional switching allows reverse current from VOUT to VIN or VBUS for On-The-Go, (OTG) Mode. The switching is controlled by logic input EN and VIN_SEL is capable of interfacing directly with low-voltage control signal General-Purpose Input / Output (GPIO). FPF3040 is available in 1.8 mm x 2.0 mm Wafer-Level Chip-Scale Package (WLCSP), 16-bump, 0.4 mm pitch.

The input operating range is from 4 V to 6.5 V at VBUS and from 4 V to 10.5 V at VIN. The internal circuitry is powered from the highest voltage source among VIN, VBUS, and VEN. VIN, VBUS or EN is higher than 5.3 V. The signal is highest voltage among VIN, VBUS, and VEN if none of them is higher than 5.3 V. EN Voltage for Control Logic Power Supply Internal control logic is powered from the highest voltage among VIN, VBUS, and VEN. If valid VIN or VBUS higher than UVLO is applied, ON/OFF control by EN should be accomplished with VIH/VIL. If EN powers the internal control block without valid VIN and VBUS, more than 2.5 V is required on the EN pin to operate properly. Input Power Source Selection Input power source can be selected by VIN_SEL and DF_IN, respectively, depending on EN state. When EN is HIGH, the input source is selected by VIN_SEL regardless of DF_IN. If VIN_SEL is LOW, VBUS is selected. If VIN_SEL is HIGH, VIN is selected. Over-Voltage Protection (OVP) FPF3040 has over-voltage protection at both VIN and VBUS. If VIN or VBUS is higher than 12 V or 7.5 V, respectively, the power switch is off until input voltage is lower than the over-voltage trip level by hysteresis voltage of 0.5 V. Table 2. Input Power Selection by VIN_SEL EN VIN>UVLO VBUS>UVLO VIN_SEL DF_IN VOUT HIGH X X LOW X VBUS HIGH X X HIGH X VIN Reverse Power Supply for OTG When EN is LOW, the input source is selected by DF_IN and the number of valid input sources. If only one input source is valid, or more than UVLO, the source is selected automatically, regardless of DF_IN, to make a charging path in case the battery is depleted. If both VBUS and VIN have valid input sources, the input source is selected by DF_IN. If DF_IN is LOW, VIN is selected. If DF_IN is HIGH or floating, VBUS is selected. DF_IN is biased HIGH with an internal 1 A pull-up current source. FPF3040 has a bi-directional switch so reverse power is allowed for On-The-Go (OTG) operation. Even if both VIN and VBUS are not available, reverse power can be also supported if internal control circuitry is powered by EN. Table 3. During FPF3040 thermal shutdown, the power switch is turned off if junction temperature reaches over 150C to avoid damage. Reverse-Current Blocking FPF3040 supports reverse-current blocking during EN LOW and an unselected channel. Thermal Shutdown Input Power Selection by DF_IN EN VIN>UVLO VBUS>UVLO VIN_SEL DF_IN VOUT LOW YES NO HIGH X VIN LOW NO YES LOW X VBUS LOW YES YES LOW Floating VBUS LOW YES YES HIGH LOW VIN LOW NO NO X X Floating Wireless Charging System FPF3040 can be used for an input power selector supporting Travel Adaptor (TA) and Wireless Charging (WC) with a single-input-based battery charger or Power Management IC (PMIC), including a charging block as shown in Figure 31. The system can recognize an input power source change between 5 V TA and 5 V WC without detection circuitry because FPF3040 has a 100 ms transition delay. OTG Mode can be supported without an additional power path, such as a MOSFET. VIN_SEL can be the status output to indicate which input power source is used during EN is LOW. If VIN is used, VIN_SEL shows high. If VBUS is used, VIN_SEL shows LOW.
