Description
The VN808SR is a monolithic device designed in STMicroelectronics VIPower M0-3 technology, intended for driving any kind of load with one side connected to ground. Figure 1. Block diagram

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 maintain junction temperature between TTSD and TR. If this condition makes case temperature reach TCSD, overloaded channel is turned OFF and and will restart only when case temperature has decreased down to TCR( see waveform 3 Figure 7 on page 10). 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 61131
