HIGH SIDE DRIVER

The VND5E008AY-E is a device made using STMicroelectronics VIPower MO-5 technology. It is intended for driving resistive or inductive loads with one side connected to ground. Active VCC pin voltage clamp protects the device against low energy spikes. This device integrates an analog current sense which delivers a current proportional to the load current when CS_DIS high leads the current sense pin in high impedance. Fault conditions such as overload, overtemperature or open-load are reported via the current sense pinOutput current limitation protects the device in overload condition. In case of long overload duration, the device limits the dissipated power to safe level up to thermal shutdown intervention. Thermal shutdown with automatic restart allows the device to recover normal operation as soon as fault condition disappears.
