Description
The FPF3042 is an 18 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 4.0 V
to 12.4 V at both V
BUS
and V
IN
to align with the needs of
high-voltage portable device power rails.
Both V
IN
and V
BUS
have the over-voltage protection of
14 V (typical) to avoid damage to the system.
V
IN
and V
BUS
bidirectional 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).
FPF3042 is available in 1.76 mm x 1.96 mm Wafer-
Level Chip-Scale Package (WLCSP), 16-bump, 0.4 mm
pitch.
