As per its creator, the ISL2802x family of digital power monitors supports a wide common mode input voltage range of 0V to 60V, reportedly the industry’s widest. The family includes three devices offering a capabilities that include bi-directional, high-side, and low-side digital current sense and voltage monitors with a serial interface. The ISL28023 is a PMBus compatible digital power monitor that integrates analog comparators, a voltage regulator, DAC, and a low voltage auxiliary channel. The ISL28025 integrates analog comparators and an integrated voltage regulator. The integrated analog comparators for the ISL28023/5 allow for continuous monitoring of the inputs. This results in a response time of 500 ns. Additionally, the ISL28022 suits cost constrained applications.
The ISL2802x family features and specs include:
• Monitors supply voltages up to 60V
• Digital output via serial interface that is I2C and SMBus and PMBus compatible
• I2C operates down to 1.2V
• Operating voltages from 3V to 5.5V and consuming an average current of just 800µA
• User defined threshold alerts (OV,OC,UV)
• Integrated 8-bit voltage output margin DAC
• Internal 3.3V voltage regulator
• Auxiliary channel for monitoring current and voltage on additional channels
• Auxiliary channel can be configured as an external temperature sensor with an addition of a diode
• Real-time alerts (500 ns response time)
• Internal temperature sensor with average accuracy of +1C
• Wide specified temperature range (-40ºC to 125ºC)
Pricing for the ISL2802x devices starts at $0.95 each/1,000. For more information, visit http://go.intersil.com/digital-power-monitor.html
