Original Abstract Submitted

A crash detection circuit of a battery management unit (BMU), includes a reference voltage generator configured to generate a reference voltage in response to a crash 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 crashed signal corresponding to the crash signal and to output a crash detection signal in response to the processed crash signal having a duration greater than or equal to a minimum retention time and at a voltage greater than or equal to the reference voltage.
