VN808CM-E, VN808CM-32-E Datasheet Octal channel high-side driver Features CMOS compatible input Junction overtemperature protection Case overtemperature protection for thermal independence of the channels Current limitation PowerSO-36 Shorted load protection Undervoltage shutdown Protection against loss of ground Very low standby current Compliance to 61000-4-4 IEC test up to 4 kV 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 T and T . If this condition causes the case temperature to trigger T , then JSD R CSD overloaded channels are turned OFF and can be turned back ON only when the case temperature decreases down to T . CR . Non- overloaded channels continue to operate normally. The device automatically Product status link turns OFF in case of ground pin disconnection. This device is especially suitable for VN808CM-E industrial applications conforming to IEC 61131.
