Product Overview
FAN54161: 6A Direct-Charger with Advanced Safety Monitoring
For complete documentation, see the data sheet.
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.
