Precision Digital Power Monitor with Real Time Alerts

The ISL28025 is a bidirectional high-side and low-side digital

current sense and voltage monitor with a serial interface. The

device monitors power supply current and voltage, which

provides the digital results along with calculated power. The

ISL28025 provides tight accuracy of less than 0.1% for both

voltage and current monitoring.

Features

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

• Voltage gain error. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 0.05%

• Current gain error. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 0.05%

• High or low (RTN) side sensing

The V power can either be externally supplied or internally

regulated, which allows the ISL28025 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.

• Bidirectional current sensing

• Auxiliary low voltage input channel

• ∆∑ADC, 16-bit native resolution

• Programmable averaging modes

• Internal 3.3V regulator

An 8-bit voltage DAC enable DC/DC converter output voltage

margining (20 Pin QFN) Fault indication includes Bus Voltage

window and over-current fast fault logic indication. The

ISL28025 includes an integrated temperature sensor for

monitoring.

• Internal temperature sense

• Over-voltage/undervoltage and current fault monitoring with

500ns detection delay

• 8-bit voltage output DAC (20 Pin QFN)

The ISL28025 serial interface is PMBus compatible and

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

1.3mA and is available in the space saving 16 ball WLCSP

package. It is also available in a 20 lead QFN 4x4 (1.85SQmm

EPAD) The parts operate across the full industrial temperature

range from -40°C to +125°C.

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

• 55 I C slave addresses

Applications

• Data processing servers

• DC power distribution
