Description
The FPF2411 is a 6 V / 6 A-rated bi -directional load sw itch, consisting of a slew -rate-controlled, low -on- resistance, P-channel MOSFET sw itch w ith protection features. The slew -rate-controlled turn-on characterist ic prevents inrush current and the resulting excessive voltage droop on the input pow er rails. The input voltage range operates from 2.3 V to 5.5 V. Bi-directional sw itching allow s reverse current from VOUT to V IN. The sw itching is controlled by active -LOW logic input the ONB pin. The FPF2411 is capable of interfacing directly w ith low -voltage control signal General -Purpose Input / Output (GPIO). The FPF2411 is available in 12-bump, 1.235 mm x 1.625 mm Wafer-Level Chip -Scale Package ( WLCSP) w ith 0.4 mm pitch.

www.onsemi.com FPF2411 — IntelliMAX™ 6 V / 6 A-Rated Bi-Direction Switch with Slew-Rate Control Operation and Application Description The FPF2411 is an ultra-low-RON P-channel load sw itch w ith bi-directional controlled turn -on and Reverse Current Blocking (RCB). The core is a 12 mΩ P-channel MOSFET and controller capable of functioning over a w ide input operating range of 2.3 V to 5.5 V. The ONB pin, active -LOW; con trols the state of the sw itch. RCB functionality blocks unw anted rev erse current during OFF states by pow er sw itch isolation betw een PWRA and PWRB. Inrush Current Inrush current occurs w hen the device is turned on. Inrush current is depend ent on output capacitance and slew rate control capability, as expressed by: LOAD R INITIALIN OUTINRUSH It VVCI w here: COUT: Output capacitance; tR: Slew rate or rise time at V OUT; VIN: Input voltage; VINITIAL: Initial voltage at COUT, usually GND; and ILOAD: Load current. Higher inrush current causes higher input voltage drop , depending on the distributed input resistance and input capacitance. High inrush current can cause problems. FPF2411 has a 3 ms of slew rate capability under 4.2 VIN at 1 µF of C OUT and 10 Ω of R L. Inrush current can be minimized and no input voltage drop appears, as show n in Figure 16. Reverse -Current Blocking The reverse-current blocking feature protects the input source against current flow from output to input w hen the load sw itch is off by changing the internal body diode direction. Bypass Capacitor To limit the voltage drop on the input supply caused by transient inrush current w hen the sw itch turns on into a discharged load capacitor ; a capacitor must be placed betw een the PWRA or PWRB and GND pins. A ceramic capacitor of a t least 1 µF placed close to the pins is usually sufficient. Board Layout For best performance, all traces should be as short as possible. To be m ost effective, the input and output capacitors should be placed close to the device to minimize the effect that parasitic trace inductance on normal and short -circuit operation. Using w ide traces or large copper planes for all pins ( PWRA, PWRB, ONB, and GND) minimizes the parasitic electrical effects and the case-to-ambient thermal impedance.
