CRASH DETECTION CIRCUIT FOR BATTERY MANAGEMENT UNIT

This abstract first appeared for US patent application 20250136030 titled 'CRASH DETECTION CIRCUIT FOR BATTERY MANAGEMENT UNIT

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.
