产品概述
描述
The VND920 is a double chip device designed in STMicroelectronics™ VIPower™ M0-3 technology. The VND920 is intended for driving any type of load with one side connected to ground. The active VCCpin voltage clamp protects the 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 integrates an analog current sense output which delivers a current proportional to the load current. The device automatically turns off in the case where the ground pin becomes disconnected.
