VN808 OCTAL HIGH SIDE DRIVER FOR THE AUTOMATION MARKET

The VN808 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 current limitation combined with thermal shutdown and automatic restart, protect the device against overload. In overload condition, channel turns off and back on automatically so as to maint.

Features

nd will restart only when case temperature has decreased down to TCR (see waveform 3 page 8). Non overloaded channels continue to operate normally. Device automatically turns off in case of ground pin disconnection. This device is especially suitable for industrial applications conform to IEC 1131 (Programmable Controllers International Standard).
