... ON 0. µA S Description The VNQ500 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 current limitation, combined with latched thermal shutdown, protect the device against overload. In the case of over temperature of one channel the relative I/O pin is pulled down ...
