Features
Type VN751S

RDS(on) 60m

Iout 2.5A

VCC 36 V SO-8

CMOS compatible input Thermal shutdown Shorted load protection Undervoltage and overvoltage shutdown Protection against loss of ground Very low stand-by current Compliance to 61000-4-4 IEC test up to 4KV

Description
The VN751S is a monolithic device designed in STMicroelectronics VIPower M0-3 Technology, intended for driving any kind of load with one side connected to ground. Active VCC pin voltage clamp protects the device against low energy spikes. Active current limitation combined with thermal shutdown and automatic restart protect the device against overload. Device automatically turns off in case of ground pin disconnection. This device is especially suitable for industrial applications in norms conformity with IEC 611312 (Programmable Controllers International Standard)
