The VN808-32-E is a monolithic device designed in STMicroelectronics VIPower M0-3 technology, intended to drive 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, the channel turns off and on again automatically so to maintain the junction temperature between TTSDand TR. If this condition makes case temperature reach TCSD, overloaded channels are turned off and restart only when the case temperature decreases down to TCR. 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.
