Battery Charging-IC - ON Semiconductor
Description
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.
