Overview
The VND5T100LAJTR-E is a monolithic device produced by STMicroelectronics, utilizing their VIPower technology. It is designed as a double channel high-side driver with analog current sense, specifically tailored for 24 V automotive applications. The device is capable of driving resistive or inductive loads with one side connected to the ground. It 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. The device includes various protection mechanisms such as overload, overtemperature, and short to VCC detection, and it latches off in case of overload or thermal shutdown.
