VN808-E/VN808-32-E Datasheet Octal channel high-side driver Features V /2 compatible input CC Junction overtemperature protection Case overtemperature protection for thermal independence of the channels Current limitation Short-circuit 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 VN808-E and VN808-32-E are monolithic devices, realized 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 conditions, the channel turns OFF and ON again automatically in order to maintain the junction temperature between T and T . If this condition causes case JSD R temperature reach T ,overloaded channels are turned OFF and restart only when CSD case temperature decreases down toT . Non-overloaded channels continue to CR operate normally. The device automatically turns OFF in case of ground pin disconnection. This device is especially suitable for industrial applications conform to Product status link IEC 61131. VN808-E Figure 1.
