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.

3 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. Symbol Parameters Min. Max.
