Description
The FPF3040 is a 20 V-rated Dual-Input Single-Output
(DISO) load switch consisting of two channels of slew-
rate-controlled, low-on-resistance, N-channel MOSFET
switches with protection features. The slew-rate-
controlled 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 V_BUS and from 4 V to 10.5 V at V_IN to
align with the needs of low-voltage portable device
power rails.
V_IN and V_BUS have the over-voltage protection
functionality of typical 12 V and 7.5 V, respectively, to
avoid unwanted damage to system.
V_IN and V_BUS bi-directional switching allows reverse
current from V_OUT to V_IN or V_BUS for On-The-Go, (OTG)
Mode. The switching is controlled by logic input EN and
V_{IN_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.
