The VND05B is a double channel high side smart power solid state relay designed for driving resistive or inductive loads. It features thermal shutdown, undervoltage protection, open drain diagnostic output, and more.
The VNDO5B is a monolithic device designed in STMicroelectronics VIPower technology, intended for driving resistive or inductive loads with one side connected to ground. The device features two channels and a common diagnostic output that indicates open load conditions, overtemperature, and stuck-on states. It includes built-in thermal shutdown protection and undervoltage protection to ensure safe operation.
| Drain-Source breakdown voltage | 40 V |
|---|---|
| Supply voltage range | 6 to 26 V |
| Thermal shutdown temperature | 440 to 480 °C |
The simplest method is to insert a Schottky diode between pin 2 (GND) and ground.
It indicates open load in on-state, open load in off-state, overtemperature conditions, and stuck-on to Voc.
