Overview
The VND5004ATR-E, produced by STMicroelectronics, is a double 4mΩ high-side driver with analog current sense, designed for automotive applications. This device utilizes STMicroelectronics' VIPower technology and is intended for driving resistive or inductive loads with one side connected to ground. It features active VCC pin voltage clamp and load dump protection, ensuring robustness against transients on the Vcc pin. The device also integrates an analog current sense that delivers a current proportional to the load current, along with various protection mechanisms such as undervoltage shutdown, overvoltage clamp, and thermal shutdown with automatic restart.
