FAN54161

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.
