BATTERY POWER MANAGEMENT PROTECTION BOARD, QUICK SHUTDOWN METHOD AND QUICK DISCHARGE CIRCUIT THEREOF

Abstract

A battery power management protection board, a quick shutdown method and a quick discharge circuit thereof are provided. The quick shutdown method for the battery power management protection boar includes: receiving a battery voltage to input a first divided voltage to a comparator; receiving a discharge switch control voltage to input a second divided voltage to the comparator; outputting a conduction voltage, if the comparator determines that the first divided voltage is higher than the second divided voltage; receiving, by a ground path switch, the conduction voltage to turn on a ground path; and discharging a remaining capacitance of the battery power management protection board rapidly through the ground path.
