Description
The FPF2498 advanced load-management switch
targets applications requiring a highly integrated
solution. It disconnects loads powered from the DC
power rail (<12 V) with stringent off-state current targets
and high load capacitances (<100 µF). The FPF2498
consists of a slew-rate controlled low-impedance
MOSFET switch. FPF2498 has over-voltage protection
and over-temperature protection.

Absolute Maximum Ratings
Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be
operable above the recommended operating conditions and stressing the parts to these levels is not recommended.
In addition, extended exposure to stresses above the recommended operating conditions may affect device reliability.
The absolute maximum ratings are stress ratings only.
