High Current Charging Switch with Protection

The FAN54151 is a low loss, high current, I2C controlled switch. Built in protection monitors the ICs input and output for over- and under-voltage as well as over- and under-current. The system protection is provided by controlling the gate voltages of a pair of N-channel MOSFETs to ensure that the output stays within a safe operating range. If a fault is detected, the FAN54151 will turn off the N-channel FETs and notify the host system via configurable interrupts. Additionally, the FAN54151 includes an integrated temperature sensor and battery cell voltage monitor that provides additional protection. The FAN54151 utilizes a 20-Bump, 0.5 mm pitch WLCSP package.
