VNI2140J

VNI2140 Dual high side smart power solid state relay Datasheet - production data Description The VNI2140J is a monolithic device designed using STMicroelectronics VIPower technology. The device drives two independent resistive or inductive loads with one side connected to PowerSSO-12 ground. Active current limitation prevents a drop in system power supply in cases of shorted-load, and built-in thermal shutdown protects the chip Features from damage due to overtemperature and short- circuit. In overload conditions, channel turns OFF Nominal current: 0.5 A per channel and ON automatically to maintain the junction Shorted-load protections temperature between TTSD and TR. If the case temperature reaches TCSD, the overloaded Junction overtemperature protection channel is turned OFF and restarts only when Case overtemperature protection for thermal case temperature decreases down to TCR. In independence of the channels order to avoid high-peak current from the supply, Thermal case shutdown restart not when more than one channel is overloaded the simultaneous for the various channels TCSD restart is not simultaneous. Non overloaded channels continue to operate Protection against loss of ground normally. The open-drain diagnostics output Current limitation 1 A per channel indicates overtemperature conditions and open- Undervoltage shutdown load in off state.
