Overview
The VN5012AK-E is a monolithic device manufactured by STMicroelectronics using their VIPower® M0-5 technology. This high-side switch is designed to drive resistive or inductive loads with one side connected to ground. It features an active VCC pin voltage clamp to protect against low energy spikes, as specified in the ISO7637 transient compatibility table. The device includes an analog current sense that delivers a current proportional to the load current, and it has various protection mechanisms such as undervoltage shutdown, overvoltage clamp, and thermal shutdown with automatic restart.
