Quad High-Side Solid-State Relay Saves Energy by Cutting On Resistance
STMicroelectronics announced a quad high-side intelligent power switch (IPS) - the VNI4140K - which is produced using the latest generation of the company's VIPowerT technology to achieve a 50 percent saving in Rds(on) compared to earlier devices with the same die size. In addition to over-temperature protection for safe operation when current draw is too high, the switch's case over-temperature protection independently limits the PCB temperature. Channels restart independently after a case thermal shut-down, to limit the peak current. The VNI4140K provides short-circuit and over-current protection, under-voltage shut-down, fast demagnetization for safe operation with large inductive loads, and protection against loss of ground. Diagnostic outputs are open drain to enable wired-OR configuration with other devices, and the logic inputs are 3.3V CMOS/TTL compatible. The switch conforms fully to the IEC 61131-2 standard for programmable logic devices. Engineering samples of the VNI4140K, in the PowerSSO24 package, are available now, with volume production planned for January 2008. It is priced at $1.80 in quantities of 10,000 pieces.
