LOAD/CHARGER DETECTION CIRCUIT, BATTERY MANAGEMENT SYSTEM COMPRISING THE SAME AND DRIVING METHOD THEREOF

摘要

Disclosed are a load/charger detection circuit, a battery management system comprising the same and a driving method thereof. The load/charger detection circuit includes a current source; a current mirror connected to the current source to copy a current of the current mirror; at least two resistors connected between a first terminal providing a corresponding voltage to a charger or a load and a power supply; and a zener diode connected between the first terminal and the current mirror.
