VNI4140K

Product status VNI4140K VNI4140K-32 Product label VNI4140K, VNI4140K-32 Datasheet Quad high-side smart power solid-state relay Features Operating output current: 0.6 A (VNI4140K) or 1.0 A (VNI4140K-32) per channel Per channel short-circuit protection Per channel overtemperature protection Thermal case protection Not simultaneous channel reactivation at Thermal case reset All type of loads (resistive, capacitive, inductive load) are driven Loss of GND protection Undervoltage shutdown with hysteresis Overvoltage protection (VCC clamping) Very low supply current Per channel open drain thermal fault pins 5 V and 3.3 V compatible I/Os Fast demagnetization of inductive loads Designed to meet IEC61131-2, IEC61000-4-4, and IEC61000-4-5 ESD according to IEC 61000-4-2 up to ±25 kV Applications Programmable logic control Industrial PC peripheral input/output Numerical control machines Description The VNI414K (for loads up to 0.6 A) and VNI4140K-32 (for loads up to 1.0 A) are monolithic 4-channel drivers featuring very low RDS(on) and per-channel diagnostic. The ICs, realized in STMicroelectronics™ VIPower™ technology, are intended to drive any kind of load with one side connected to ground. Active channel current limitation combined with thermal shutdown, independent for each channel, and automatic restart, protect the device against overload. A channel in an overload condition overheats and turns OFF and back ON automatically in order to maintain it...
