Overview
The VND5T100AJ-E is a monolithic device produced by STMicroelectronics, utilizing their VIPower technology. It is designed to drive resistive or inductive loads with one side connected to the ground. The 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 a reset option via the fault reset standby pin. A permanent low level on the inputs and fault reset standby pins disables all outputs and sets the device in standby mode.
