Overview
|
|
|
NT1732A series are accurate secondary battery
protection ICs for 1/2/3-cell Lithium-Lon/Lithium-Polymer battery packs, on which a precise voltage detection circuit with a specific reference is embedded. NT1732A 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, NT1732A series activate an external MOSFET to blow the three-terminal protection fuse, permanently disabling the battery pack. |
