Output protector for charger

An output protector for charger connected to an output terminal of a charger, wherein the output protector (100) comprises a MOS tube (1) as electronic switch, a power output V+ terminal (3), a light switchover signal terminal (2) connected to the grid of the MOS tube (1), a VCC terminal (8) connected to the grid of the MOS tube (1) through a first capacitor (31), a power GND terminal (4) connected to the source of the MOS tube (1), and a power output V− terminal (5) connected to the drain of the MOS tube (1);

• the power output V− terminal (3) and power GND terminal (4) are connected to the output terminal anode and cathode of charger respectively;
• the light switchover signal terminal (2) is connected to the charging state signal output end of charger;
• the VCC terminal (8) is connected to the VCC terminal of charger;
• the power output V+ terminal (3) and power output V− terminal (5) are connected to the anode and cathode of battery (6) respectively, and the output protector (100) has a triode on-unit (7) which drives the MOS tube (1) after the power output V+ terminal (3) and power output V− terminal (5) are connected to the anode and cathode of battery (6) respectively.
