February 4, 2016 Precision Digital Power Monitor
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 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 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 I2C/SMBus interface Wide VCC 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 I2C . 3.4MHz Related Literature DC/DC, AC/DC converters AN1955, “Design Ideas for Intersil Digital Power Monitors” Battery management/charging AN1875, “ISL28022 Digital Power Monitor Evaluation Kit
