Abstract

See full text

A chip configured to protect a battery includes a buffer circuit and a switch circuit. The buffer circuit is configured to generate a gate control signal according to a first logic control signal, a first voltage, a second voltage, and a third voltage. The switch circuit is configured to transmit the second or the third voltage to the buffer circuit. The switch circuit includes an invert circuit and a select circuit. The invert circuit is configured to invert a second logic control signal to a third logic control signal. The select circuit is configured to select the second or third voltage to transmit the same to the buffer circuit according to the second logic control signal and the third logic control signal. The gate control signal is configured to turn off a power transistor when an overcharging or an over-discharging occurs.
