Description
The VN808CM-E and VN808CM-32-E are monolithic devices designed with STMicroelectronics VIPower M0-3 technology, intended to drive any kind of load with one side connected to ground. It can be driven by using a 3.3 V logic supply. Active current limitation combined with thermal shutdown and automatic restart protect the device against overload. In overload conditions, the channel turns OFF and ON again automatically to maintain the junction temperature between TJSD and TR. If this condition causes the case temperature to trigger TCSD, then overloaded channels are turned OFF and can be turned back ON only when the case temperature decreases down to TCR. Non- overloaded channels continue to operate normally. The device automatically turns OFF in case of ground pin disconnection. This device is especially suitable for industrial applications conforming to IEC 61131.

7.2 Thermal protection
when it falls below the reset threshold (TJR). This behavior continues while the fault on the output is present. temperature of each channel in fault and case temperature are below the respective reset thresholds.

7.3 STATUS indication
STATUS behavior when TJSD is triggered before TCSD and when TCSD is triggered before TJSD, respectively.

- Placing a resistor (R GND) between IC GND pin and load GND
- Placing a diode between IC GND pin and load GND
