过放电解除电压 2.0 V ~ 3.4 V*2 精度±100 mV
放电过电流检测电压1 0.010 V ~ 0.100 V (1 mV进阶) 精度±3 mV
放电过电流检测电压2 0.030 V ~ 0.200 V (1 mV进阶) 精度±5 mV
负载短路检测电压 0.050 V ~ 0.500 V (5 mV进阶) 精度±20 mV
充电过电流检测电压 −0.100 V ~ −0.010 V (1 mV进阶) 精度±3 mV
各种检测延迟时间仅通过内置电路即可实现 (不需要外接电容)
可选择向0 V电池充电的功能
允许、禁止
可选择休眠功能
有、无
可选择放电过电流状态的解除条件
断开负载、连接充电器
可选择放电过电流状态的解除电压
放电过电流检测电压1 (Vdiov1),
放电过电流解除电压 (Vriov) = Vdd × 0.8 (典型值)
高耐压
VM端子、CO端子 : 绝对最大额定值28 V
工作温度范围广
Ta = −40°C ~ +85°C
消耗电流低
工作时 : 2.0 μA (典型值)、4.0 μA (最大值) (Ta = +25°C)
休眠时 : 50 nA (最大值) (Ta = +25°C)
过放电时 : 500 nA (最大值) (Ta = +25°C)
无铅 (Sn 100%)、无卤素

*1. 过充电解除电压 = 过充电检测电压 − 过充电滞后电压
(过充电滞后电压为0 V或者可在0.1 V ~ 0.4 V的范围内以50 mV为进阶单位进行选择)

*2. 过放电解除电压 = 过放电检测电压 + 过放电滞后电压
(过放电滞后电压为0 V或者可在0.1 V ~ 0.7 V的范围内以100 mV为进阶单位进行选择)

用途

  • 锂离子可充电电池组
  • 锂聚合物可充电电池组
