Rev 5.00
March 18, 2016 Precision Digital Power Monitor with Margining Features The ISL28023 is a bidirectional high-side and low-side digital
current sense and voltage monitor with a serial interface. The
device monitors power supply current, voltage and provides
the digital results along with calculated power. The ISL28023
provides tight accuracy of 0.05% for both voltage and current
monitoring. The auxiliary input provides an additional power
monitor function. Bus voltage sense range 0V to 60V
Voltage gain error . 0.05%
Current gain error . 0.05%
Internal temperature sensor accuracy +1.0В°C
High or low (RTN) side sensing
Bidirectional current sensing
Auxiliary low voltage channel
∆∑ADC, 16-bit native resolution
Programmable averaging modes
Internal 3.3V regulator
Internal temperature sense
Overvoltage/undervoltage and current fault monitoring with
500ns detection delay 8-bit voltage output DAC I2C/SMBus/PMBus interface that handles 1.2V supply The VCC power can either be externally supplied or internally
regulated, which allows the ISL28023 to handle a …
