Description

The VNQ810P-E is a quad HSD formed by assembling two VND810P-E chips in the same SO-28 package. The VNQ810P-E is a monolithic device made by using STMicroelectronics VIPower™ M0-3 technology, intended for driving any kind of load with one side connected to ground. Active V device against low energy spikes (see ISO7637 transient compatibility table).

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 V Device automatically turns off in case of ground pin disconnection.

pin voltage clamp protects the

is detected in the off-state.
