The ISL28022 is a bidirectional high-side and low-side digital current sense and voltage monitor with serial interface. The device monitors current and voltage and provides the results digitally along with calculated power. The ISL28022 provides tight accuracy of less than 0. 3% for both voltage and current monitoring over the entire input range. The digital power monitor has configurable fault thresholds and measurable ADC gain ranges. The ISL28022 handles common-mode input voltage ranging from 0V to 60V. The wide range permits the device to handle telecom, automotive and industrial applications with minimal external circuitry. Both high- and low-side ground sensing applications are easily handled with the flexible architecture. The ISL28022 consumes an average current of just 700μA and is available in a 10 Ld MSOP package. The ISL28022 is also offered in a space saving 16 Ld QFN package. The part operates across the extended temperature range from -40°C to +125°C
