ISL28025 Precision Digital Power Monitor

Renesas Electronics ISL28025 Precision Digital Power Monitor 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, which 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 V_CC power can either be externally supplied or internally regulated, which allows the ISL28025 to handle a common-mode input voltage range from 0V to 60V. The wide range permits the device to handle telecom, automotive and industrial applications with minimal external circuitry. An 8-bit voltage DAC enables DC-DC converter output voltage margining. Fault indication includes Bus Voltage window and over-current fast fault logic indication. The ISL28025 includes an integrated temperature sensor for monitoring. The ISL28025 serial interface is PMBus compatible and operates down to 1.2V.
