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)

For products that are Customized and under Non-cancellable & Non-returnable, Sales & Conditions apply.

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.
