Overview
The VN5T016AH-E is a high-side driver device developed by STMicroelectronics using their VIPower technology. It is designed to drive resistive or inductive loads with one side connected to ground. This device features an active VCC pin voltage clamp to protect against low energy spikes and integrates an analog current sense that delivers a current proportional to the load current. Fault conditions such as overload, overtemperature, or short to VCC are reported via the current sense pin. The device includes output current limitation and latches off in case of overload or thermal shutdown, with the ability to reset via a low level pass on the fault reset standby pin.
