ISL28022

Precision Digital Power Monitor

FN8386

Rev 8.00

February 4, 2016

The ISL28022 is a bidirectional high-side and low-side digital

current sense and voltage monitor with serial interface. The

device monitors current and voltage and provides the results

digitally along with calculated power. The ISL28022 provides

tight accuracy of less than 0.3% for both voltage and current

monitoring over the entire input range. The digital power

monitor has configurable fault thresholds and measurable

ADC gain ranges.

Features

• Bus voltage sense range . . . . . . . . . . . . . . . . . . . . . . 0V to 60V

• 16-bit ∑∆ADC monitors current and voltage

• Voltage measuring error . . . . . . . . . . . . . . . . . . . . . . . . . <0.3%

• Current measuring error . . . . . . . . . . . . . . . . . . . . . . . . . <0.3%

• Handles negative system voltage

The ISL28022 handles common-mode input voltage ranging

from 0V to 60V. The wide range permits the device to handle

telecom, automotive and industrial applications with minimal

external circuitry. Both high- and low-side ground sensing

applications are easily handled with the flexible architecture.

• Overvoltage/undervoltage and current fault monitoring

• I C/SMBus interface

• Wide V range . . . . . . . . . . . . . . . . . . . . . . . . . . . . 3V to 5.5V

• ESD (HBM). . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 8kV

The ISL28022 consumes an average current of just 700µA and is

available in a 10 Ld MSOP package. The ISL28022 is also offered

in a space saving 16 Ld QFN package. The part operates across

the extended temperature range from -40°C to +125°C.

• Supports high speed I C . . . . . . . . . . . . . . . . . . . . . . . 3.4MHz

Applications

• Routers and servers

• DC/DC, AC/DC converters

• Battery management/charging

• Automotive power
