Intersil ISL28022EVKIT1Z, Power Monitor Evaluation Kit for ISL28022

The ISL28022EVKIT1Z and ISL28023EVKIT1Z, digital power monitor evaluation kits demonstrate the functionality of the ISL28022 and ISL28023, Precision Digital Power Monitors. They feature bidirectional, high-side and low-side digital current sense and voltage monitoring with serial interface. The ISL28023 includes an 8-bit voltage output DAC which enables output voltage margining with DC-DC converters.

Bus voltage sense from zero to 60 V
16-bit ADC monitors current and voltage
Handles negative system voltage
Over-voltage/Under-voltage and current fault monitoring
Real-time alerts
I²C/SMBus serial interface; operates down to 1.2 V
Operating voltages from 3 V to 5.5 V
Internal 3.3 V voltage regulator (ISL28023)
Internal Temperature Sensor accuracy: +1°C (ISL28023)

Current Sensing Amplifiers have a voltage output that is proportional to the volt drop across a very low value resistor, usually in a high-current power rail. Hence they measure the current flowing in that power rail.
