A collision detection circuit of a battery management unit (BMU) includes: a reference voltage generator configured to generate a reference voltage in response to a collision signal output from a vehicle being input to the BMU; and a comparator configured to compare the reference voltage generated from the reference voltage generator with a processed collision signal corresponding to the collision signal, and output a collision detection signal in response to the processed collision signal having a duration greater than or equal to a minimum retention time and being at a voltage greater than or equal to the reference voltage.

    一种电池管理单元(BMU)的碰撞检测电路,包括:参考电压生成器,被配置为响应于从车辆输出的碰撞信号被输入到BMU而生成参考电压;以及比较器,被配置为将从参考电压生成器生成的参考电压与对应于碰撞信号的处理的碰撞信号进行比较,并且响应于处理的碰撞信号具有大于或等于最小保持时间的持续时间并且处于大于或等于参考电压的电压,输出碰撞检测信号。
