FAN54161 Battery Charging IC, 98% Efficient, Safe 6 A Direct with Regulation and Protection The FAN54161UCX is a low loss direct charger which charges the battery safely at 6 A and provides active protection, regulation and monitoring features. Integrated Protection and Regulation features control a pair of MOSFETs to ensure that the FAN54161UCX output voltage and current stay within a safe programmed operating range. Configurable hardware based safety features turn off the MOSFET in the event of a fault and notify the system. An integrated 10−bit Analog−to−Digital Converter (ADC) provides real−time monitoring of input, output voltage, currents and temperature so that the system host or microcontroller can effectively use this information to optimize adapter and charger configuration.

WLCSP−42 Pin Assignments Table 1. PIN DESCRIPTIONS Name Position Type ADR E2 Digital Input Description I2C Slave Device Address Selection Pin Refer to I2C Interface section for details ADR logic level must be set before releasing RESET_N high. Recommend connecting this pin to the appropriate logic level before power is applied (VBUS or VOUT). GND F2 Ground Device Ground Connect to the ground node in the PCB. INT_N C2 Open−Drain Interrupt Output (Active Low) Digital Output Pull−up with 100 kW resistor to logic supply voltage. When an un−masked interrupt bit is set this pin will assert low. Connect to GND if not used. RESET_N D2 Digital Input Reset Input (Active Low) 0 (Logic Low) – IC held in reset condition (lowest power state), switch is open, ADC is disabled, and I2C communication is not available. 1 (Logic High) – IC logic allowed to operate, switch closed if SW_EN = 1; ADC enabled if ADC_EN = 1. If not used, it is recommended to pull−up to VOUT. SCL SDA B1 Digital I.
