Overview
General Description AS8506C Battery Cell Monitor and Balancer IC The AS8506C is a battery management IC dedicated to support cell voltage measurement, monitoring, cell balancing and temperature measurement functions in Li-Ion battery stacks for industrial/consumer/PV battery applications.
Ambient temperature range is from -40°C to +85°C.
It features cell voltage diagnosis with externally adjustable upper and lower cell voltage limits, fast cell voltage capture on request through 12-bit SAR ADC, passive cell balancing by simultaneous comparison of actual cell voltages with a reference cell voltage and temperature measurement on two external NTC sensors through 12-bit ADC.
Cells that are above reference will sequentially be discharged through integrated switches and one external resistor.
There is also an active balancing option AS8506C A through factory setting to sequentially charge cells which are below reference from an external DC-DC Flyback converter and an integrated low side dri...
