Description
The FPF2895V features a 28 V and 5 A rated current limit power
switch, which offers Over−Current Protection (OCP), Over−Voltage
Protection (OVP), and True Reverse Current Block (TRCB) to protect
system. It has low On−resistance of typical 27 Wm with WL−CSP can
operate over an input voltage range of 4 V to 22 V.
The FPF2895V supports 15% of current limit accuracy,
over-current range of 500 mA to 2 A and 10% of current limit
accuracy, over−current range of 2 A to 5 A , flexible operations such as
selectable OVP, selectable ON polarity and selectable OCP behavior,
which can be optimized according to system requirements.
The FPF2895V is available in a 24−bump, 1.67 mm x 2.60 mm
Wafer−Level Chip−Scale Package (WL-CSP) with 0.4 mm pitch.
