美上美/MITSUMI MM3474G02VBE TSOP-20D 3到5个电池的锂离子/锂聚合物电池保护IC 

Outline

MM3474G02VBE is an overcharge, overdischarge and overcurrent protection IC for a lithium-ion / lithiumpolymer rechargeable secondary battery. Lithium-ion / lithium-polymer rechargeable secondary battery overcharge each cell, over discharge, and discharge overcurrent, short circuits can be detected.

This supports 3 to 5 serial cells connected in series, and switches over to the desired no. of cells by sending High / Low signal to SEL terminal.

This also provides the control terminals of output over discharge detection (SDC) and output over charge detection (SOC), which allows configuring an application with fewer external parts for 6 or more cells connected in series.

MM3474G02VBE Features (Unless otherwise specifi ed, Topr=+25°C)
(1) Range and accuracy of detection / release voltage
(2) Each detection delay time set by the external capacitor
(3) The setting for three cell , for four cell , and for fi ve cell protection can be set with the SEL1 pin
and the SEL2 pin.
(4) The charge and discharge of the battery can be controlled with SDC pin and SOC pin.
(5) Low current consumption
(6) Absolute maximum ratings
