ISL28025: Precision Digital Power Monitor with Real Time Alerts

The ISL28025 is a bidirectional high side and low side digital current sense and voltage monitor with a serial interface. The device monitors power supply current and voltage and provides the digital results along with calculated power. The ISL28025 provides tight accuracy of less than 0.1% for both voltage and current monitoring. The ISL28025 serial interface is PMBus compatible and operates down to 1.2V voltage. It draws an average current of just 1.3mA and is available in the space saving 16 ball WLCSP package.
