Description

NT1732B series are accurate secondary battery

protection ICs for 1/2/3-cell Lithium-Lon/LithiumPolymer battery packs, on which a precise voltage

detection circuit with a specific reference is embedded.

NT1732B series monitor individual cell voltages. If

any cell voltage reaches or goes over the specified

voltage and lasts for a period longer than the delay

time set, NT1732B series activate an external

MOSFET to blow the three-terminal protection fuse,

permanently disabling the battery pack.
