The VN31 is a monolithic device made using STMicroelectronics VIPower Technology, intended for driving resistive or inductive loads with one side grounded. It features thermal shut-down protection, under voltage protection, open drain diagnostic output, fast demagnetization of inductive loads, and very low stand-by power dissipation.
The VN31 is a monolithic device designed to drive resistive or inductive loads with one side grounded. It features built-in thermal shut-down protection against over-temperature and short circuits, as well as under-voltage protection.
The device includes an open-drain diagnostic output that indicates open load conditions (in both off and on states), output shorts to Vcc, and over-temperature events. Additionally, it provides fast demagnetization for inductive loads by applying a negative voltage at turn-off.
| Maximum Continuous Output Current | 31 A @ Tc= 85°C |
|---|---|
