ISL28025 FN8388
Rev.5.00
Nov 9, 2017 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 The VCC 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 Bus voltage sense range 0V to 60V Voltage gain error . 0.05% Current gain error . 0.05% High or low (RTN) side sensing Auxiliary low voltage input channel ∆∑ADC, 16-bit native resolution Programmable averaging modes 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 3.3V regulator 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)В The parts operate across the full industrial temperature
range from -40В°C to +125В°C. I2C/SMBus/PMBus interface that handles 1.2V supply Internal temperature sense Over-voltage/undervoltage and current fault monitoring with …
