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  
CC  
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.
