FPF1321
Description
The FPF1320/21 is a Dual- Input Single- Output (DISO) load switch consisting of two sets of slew- rate controlled, low on- resistance, P- channel MOSFET switches and integrated analog features
. The slew- rate- controlled turn- on characteristic prevents inrush current and the resulting excessive voltage droop on the power rails. The input voltage range operates from 1.5 V to 5.5 V to align with the requirements of low- voltage portable device power rails. FPF1320/21 performs seamless power- source transitions between two input power rails using the SEL pin with advanced break- before- make operation.
FPF1320/21 has a TRCB function to block unwanted reverse current from output to input during ON/OFF states. The switch is controlled by logic inputs of the SEL and EN pins, which are capable of interfacing directly with low- voltage control signals (GPIO).
FPF1321 has 65 W on- chip load resistor for output quick discharge when EN is LOW.
FPF1320/21 is available in 1.0 mm x 1.5 mm WLCSP, 6-...
