onsemi Power Distribution Switches, Load Drivers FPF2025

The FPF2025 is a P-Channel MOSFET load switch designed for low-power applications, featuring a fixed current limit of 100 mA. It operates within an input voltage range of 1.6 V to 5.5 V, making it suitable for various portable devices. The device has a typical R_DS(ON) of 280 mOc at 1.8 V, which contributes to its low power consumption with an average quiescent current of just 1 OºA. The FPF2025 includes several protective features such as under-voltage lockout (UVLO), thermal shutdown, and fault signaling through a CMOS output. It also supports an auto-restart function that reactivates the switch after a fault condition is cleared, provided the ON pin remains active. The product is housed in a compact 6-ball CSP package, measuring 1.0 x 1.5 mm, which is advantageous for space-constrained designs. This load switch is suitable for applications in PDAs, cell phones, GPS devices, digital cameras, and MP3 players, making it a versatile choice for engineers looking to implement efficient power management solutions in small electronic devices.
