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 the ground. Active current limitation combined with thermal shutdown and automatic restart, protects 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 reach TCSD, overloaded channels are turned OFF and restarted 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 that conform to IEC 61131.
Features:-
• VCC/2 compatible input
• 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
