VN751SHigh side driver
Features CMOS compatible input Thermal shutdown Shorted load protection Undervoltage and overvoltage shutdown Protection against loss of ground Very low standby current Compliance to 61000-4-4 IEC test up to 4 kV Open drain status output
DescriptionThe 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 conformity with IEC 61131-2
programmable controllers international standard.
