VN808-32-E数据手册ST中文资料规格书

描述 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 TJSD and TR. If this condition causes case temperature reach TCSD,overloaded channels are turned OFF and restart only when case temperature decreases down toTCR. 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 conform to IEC 61131.
