POWER MANAGEMENT ICS
Cell Monitor and Cell 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 applications.
The AS8506C features simultaneous cell voltage comparison with upper and lower threshold, active- or optionally passive cell balancing by simultaneous comparison of actual cell voltages with a target cell voltage. Cells which are below target will either cyclically receive charge packages from an isolated DCDC converter or, optionally, cells above target will cyclically be discharged by an external resistor through integrated switches in an autonomous way. The AS8506C targets non-automotive markets with an optimized cost structure.
The AS8506C is used in li-based cell packs as well as EDLCs (Electrical Double Layer Capacitors or Supercapacitors) in the following applications:
