ABLIC S-19192 Battery Monitoring ICs
ABLIC S-19192 Battery Monitoring ICs are for automotive rechargeable batteries that include high-accuracy voltage detection circuits and delay circuits. These ICs feature switching control for 3-serial to 6-serial cell packs and can perform a self-test to confirm overcharge and over-discharge detection operations. The S-19192 battery monitoring ICs are AEC-Q100-qualified and are RoHS compliant. These ICs are lead and halogen-free. Typical applications include automotive rechargeable battery pack (EV, HEV, and PHEV).
Features
