ADM1275-2ARQZ-R7

Overview

The ADM1275-2ARQZ-R7 is a high-side current and power monitor featuring an integrated N-channel MOSFET driver. It provides precise measurement of load current and voltage to calculate real-time power consumption. The device includes programmable thresholds for overcurrent, undervoltage, and overvoltage protection with configurable delay times. It operates from a supply voltage range of 4.5 V to 60 V and supports I2C communication for configuration and data retrieval. The component is housed in a thermally enhanced 16-lead LFCSP package.

Feature Summary

• Integrated high-side N-channel MOSFET driver eliminates external pass transistor requirements
• Simultaneous measurement of input voltage and load current for accurate power monitoring
• Programmable fault thresholds with adjustable debounce timers for robust protection
• I2C-compatible digital interface for system integration and configuration

Applications

• Telecommunications infrastructure power distribution
• Industrial automation power supplies

• Medical equipment power monitoring

Procurement Notes

Verify the specific suffix ARQZ-R7 confirms the tape-and-reel packaging and temperature grade. Ensure the ordering part number matches the required pinout and thermal pad configuration. Confirm compatibility with the target I2C bus speed and logic levels. Check for any regional compliance certifications required for the end application.

Selection Notes

Select this component when integrated MOSFET driving and high-voltage monitoring are required in a compact form factor. Evaluate the maximum continuous current rating against the expected load profile. Consider the accuracy specifications at different temperature ranges relative to system requirements. Verify that the I2C address settings do not conflict with other devices on the bus.

Part Context

This part belongs to the ADM127x family of high-side power monitors. It shares architectural similarities with other models in the series but differs in specific package options and factory programming configurations. The family targets applications requiring precise power management without external discrete components for current sensing or switching.

Replacement Considerations

Direct replacements include other ADM127x variants with compatible pinouts and functionality. Verify that substitute parts support the same voltage range and I2C protocol. Ensure thermal performance characteristics match the original design constraints.
