VN808CM-E数据手册ST中文资料规格书

描述 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.
