VND5T050AK-E：Double channel high-side driver with analog current-sense for 24V automotive applications

The VND5T050AK-E is a monolithic device made using STMicroelectronics^®VIPower^®technology, intended for driving resistive or inductive loads with one side connected to ground. Active V_CCpin 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.

Fault conditions such as overload, overtemperature or short to V_CCare reported via the current sense pin.

Output current limitation protects the device in overload condition. The device will latch off in case of overload or thermal shutdown.

The device is reset by a low level pass on the fault reset standby pin.

A permanent low level on the inputs and fault reset standby pin disable all outputs and set the device in standby mode.
