MITSUMI Protection of Lithium Ion Batteries MM1414 Protection of Lithium Ion Batteries Monolithic IC MM1414 产品代理：美之通科技有限公司 电话0755 传真0755Outline This IC protects lithium ion batteries in the event of overcharge, overdischarge and overcurrent. It has the following two functions: an overcurrent detection function that turns the external FET-SW off when a problem occurs during charging, etc. and excess voltage is impressed on each battery for longer than a certain time, and an overdischarge detection function that turns the external FET-SW off when battery voltage drops below a certain voltage during discharge, in order to prevent battery overdischarge. When these functions operate, the IC is put into low consumption current mode. It also has an overcurrent detection function that turns the FET-SW off when excess current flows due to a short or the like. 该集成电路锂电保护在发生过充电，过放电和过电流。它具有以下功能：过电流检测功能，外部fet-sw过当问题发生在充电，等过电压施加在每个电池时间超过一定时间，和过放电检测功能，外部fet-sw关闭时，电池电压低于一定的电压，在放电，以防止电池过放电。当这些职能，集成电路进入低功耗电流模式。它还具有过流检测功能，将fet-sw过量电流流动时，由于短期或类似。 Temperature conditions A: Ta=-25 ~ 75°C, B: Ta=-20 ~ 70°C, C: Ta=0 ~ 50°C, D: Ta=0 ~ 40°C, E: Ta=-20 ~ 25°C Model Package Overcharge detection voltage (V) Overcharge detection voltage temperature conditions Overcharge detection hysteresis voltage (V) Overdischarge detection voltage (V) Overdischarge resumption voltage (V) Overcurrent detection voltage (mV) TSOP-20A MM1414 AV 4.350±0.025 C 200±60 2.00±0.10 3.00±0.15 150±15 CV 4.350±0.025 C 200±60 2.30±0.10 3.00±0.15 150±15 DV 4.250±0.025 C 200±60 2.30±0.10 3.00±0.15 150±15 FV 4.325±0.025 C 200±60 2.30±0.10 3.00±0.15 100±15 GV 4.295±0.025 C 8±8 2.30±0.10 3.00±0.15 150±15 Features 1.
