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 V
CC
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.
