Lithium-ion/Lithium聚合物电池的单节保护
功能特点
产品名称:Lithium-ion/Lithium聚合物电池的单节保护
产品型号:SEI8100
产品描述:
The SEI8100/8101 series are 1-cell lithium-ion/lithium polymer rechargeable battery protection ICs with high-accuracy voltage detection circuit and delay circuit. It is a 6-pin package for 1-celllithium-ion/lithium polymer rechargeable battery cells protections including over-charge detection, over-discharge detection, over-discharge current detection, over-charge current detection, load short circuiting detection and charger insertion detection functions. The OC output controls an external N-MOSFET to enable or disable the battery charging path and the OD output controls an external N-MOSFET to enable or disable the battery discharging path to protect the battery cell from damage and incident occurring. The ICs has a built-in timer circuit for protection discrimination without external delay capacitor. In SOT23-6L package, the DP pin is used for speeding up the delay circuit timer intesting.
Remark: The SEI8100 series are used in battery cells with 0 V un-chargeable and SEI8101 series are used in battery cells with 0 V chargeable.
