Abstract
Embodiments are disclosed of a battery management system (BMS). The BMS includes a pair of back-to-back transistors configured to selectively discharge battery cells of a battery pack; a high-side driver configured to control operation of the pair of back-to-back transistors; an analog front end (AFE) circuit configured to monitor a voltage of each cell within the battery pack; and a micro controller unit (MCU) configured to control and monitor the AFE circuit and provide over-voltage protection to the pair of back-to-back transistors.
