Precision Digital Power Monitor with Margining

ISL28023

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.

• Internal temperature sensor accuracy . . . . . . . . . . . . +1.0°C

• High or low (RTN) side sensing

• Bidirectional current sensing

• Auxiliary low voltage channel

The V power can either be externally supplied or internally

regulated, which allows the ISL28023 to handle a

• ∆∑ADC, 16-bit native resolution

• Programmable averaging modes

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.

• Internal 3.3V regulator

• Internal temperature sense

• Overvoltage/undervoltage and current fault monitoring with

500ns detection delay

An 8-bit voltage DAC enables a DC/DC converter output

voltage margining. Fault indication includes a Bus Voltage

window and overcurrent fast fault logic indication. A

temperature sensing option includes both internal

temperature sensor and a bias/monitor circuit for external

diode sensing.

• 8-bit voltage output DAC

• I C/SMBus/PMBus interface that handles 1.2V supply

• 55 I C slave addresses

Applications

The ISL28023 serial interface is PMBus compatible and

operates down to 1.2V voltage. It draws an average current of

just 800µA and is available in the space saving 24 Ld QFN

4mmx4mm package. The part operates across the full

industrial temperature range from -40°C to +125°C.

• Data processing servers

• DC power distribution

• Telecom equipment

• Portable communication equipment

• DC/DC, AC/DC converters
