SWITCH CONTROL DEVICE AND BATTERY PACK INCLUDING THE SAME

The invention relates to a switch control device and a battery pack including the same. The switch control apparatus includes: an overcurrent detection circuit configured to output an overcurrent detection signal if an overcurrent is detected in a current path in which a switch is set; a counter circuit configured to output a latch control signal whose voltage changes in response to the number of outputs of the overcurrent detection signal; a latch circuit configured to continuously output a latch signal if a voltage of the latch control signal is higher than a predetermined voltage; and an OFF circuit configured to output an OFF signal controlling the switch to be OFF if the overcurrent detection signal is output from the overcurrent detection circuit or the latch signal is output from the latch circuit. 本发明涉及开关控制装置和包括该开关控制装置的电池组。该开关控制装置包括：过电流检测电路，被配置为如果在设置开关的电流路径中检测到过电流，则输出过电流检测信号；计数器电路，被配置为输出锁存控制信号，该锁存控制信号的电压响应于过电流检测信号的输出的数量而改变；锁存电路，被配置为如果锁存控制信号的电压高于预定电压，则连续输出锁存信号；以及断开电路，被配置为如果从过电流检测电路输出过电流检测信号或者从锁存电路输出锁存信
