DOUBLE CHANNEL HIGH SIDE SOLID STATE RELAY

® VND920P DOUBLE CHANNEL HIGH SIDE SOLID STATE RELAY TARGET SPECIFICATION TYPE VND920P RDS(on) 16mΩ IOUT 35 A (*) VCC 36 V (*) Per channel with all the output pins connected to the PCB. CMOS COMPATIBLE INPUT PROPORTIONAL LOAD CURRENT SENSE s SHORTED LOAD PROTECTION s UNDERVOLTAGE AND OVERVOLTAGE SHUTDOWN s OVERVOLTAGE CLAMP s THERMAL SHUTDOWN s CURRENT LIMITATION s PROTECTION AGAINST LOSS OF GROUND AND LOSS OF VCC s s SO-28 (DOUBLE ISLAND) ORDER CODES PACKAGE SO-28 TUBE VND920P T&R VND920P13TR VERY LOW STAND-BY POWER DISSIPATION s REVERSE BATTERY PROTECTION (**) s www.DataSheet4U.com DESCRIPTION The VND920P is a double chip device made by using STMicroelectronics VIPower M0-3 Technology, intended for driving any kind of load CONNECTION DIAGRAM (TOP VIEW) with one side connected to ground. Active VCC pin voltage clamp protects the device against low energy spikes (see ISO7637 transient compatibility table). Active current limitation combined with thermal shutdown and automatic restart protect the device against overload. Builtin analog current sense output delivers a current proportional to the load current. Device automatically turns off in case of ground pin disconnection.
