Description
The FPF2487 features a 2-channel power switch, which
offers surge protection and Over-Voltage Protection
(OVP), to protect downstream components and
enhancing overall system robustness.
Channel one (VBUS) is an active-low, 28 V/2.5 A rated,
power MOSFET switch with an internal clamp
supporting ±100 V surge protection, highly accurate
fixed OVP at 5.95 V (±50 mV), and OTG functionality.
Channel two (VIF) is a conditional active-high, 6 V/6 A
rated, power MOSFET switch with an integrated TVS
supporting ±40 V surge protection and fixed OVP at
5.25 V (±250 mV). VIF also provides Reverse Current
Blocking (RCB) during its OFF state to minimize
leakage current.
VBUS_DET is paired with always ON LDO to power
downstream devices even with VBUS is greater than
2.5 V, even when disabled through the ONB pin. This
provides power sequence control or a host controlled
configuration in system.
The FPF2487 is available in a 15-bump, 1.6 mm x
2.2 mm Wafer-Level Chip-Scale Package (WLCSP) with
0.4 mm pitch.
