DESCRIPTION

The VND810-E is a monolithic device designed in STMicroelectronics VIPower M0-3 Technology, intended for driving any kind of load with one side connected to ground.

Active VCC pin voltage clamp protects the device against low energy spikes (see ISO7637 transient compatibility table).

SO-16

Active current limitation combined with thermal shutdown and automatic restart protects the device against overload. The device detects open load condition both in on and off state. Output shorted to VCC is detected in the off state. Device automatically turns off in case of ground pin disconnection.

Note: 1. To ensure long term reliability under heavy overload or short circuit conditions, protection and related diagnostic signals must be used together with a proper software strategy. If the device is subjected to abnormal conditions, this software must limit the duration and number of activation cycles
