ISL28023 Precision Digital Power Monitors Renesas Electronics ISL28023 Precision Digital Power Monitors with Margining are bidirectional, high-side, and low-side digital current sense and voltage monitors with a serial interface. ISL28023 monitors power supply current, voltage, and provides the digital results along with calculated power. ISL28023's auxiliary input provides an additional power monitor function. The devices provide tight accuracy of 0.05% for both voltage and current monitoring. The VCC power can either be externally supplied or internally regulated, which allows the ISL28023 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.
