VN820 - STMicroelectronics

VN820 HIGH SIDE DRIVER

The VN820, VN820SP, VN820-B5, VN820SO, VN820PT are monolithic devices made by using STMicroelectronics VIPower M0-3 Technology, intended for driving any kind of load with one side connected to ground. Active V CC pin voltage clamp protects the device against low energy spikes (see ISO7637 transient BLOCK DIAGRAM compatibility table). Active current limitati.

Features

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