ADM1176-2ARMZ-R7

Overview

The ADM1176-2ARMZ-R7 is a hot swap voltage controller from Analog Devices Inc. designed for single-channel applications. It operates within a supply voltage range of 3.15 V to 16.5 V and draws a typical operating supply current of 1.7 mA. The device supports surface mount installation in a 10-MSOP package and functions reliably across an operating temperature range of -40°C to +85°C.

Feature Summary

• Integrates digital current and voltage monitoring capabilities via an on-chip 12-bit analog-to-digital converter (ADC).
• Enables real-time access to fault status through I2C-based configuration and monitoring interfaces.
• Supports programmable features including current limit, fault timeout, and turn-on voltage settings.

Applications

• Hot swap system integration requiring precise power management
• Industrial equipment with I2C-configurable protection needs
• Telecommunications infrastructure power distribution

Procurement Notes

Verify component authenticity by cross-referencing the manufacturer part number with official Analog Devices documentation. Confirm that the specific suffix matches the required reel or cut tape packaging format. Ensure the device meets RoHS compliance standards as specified in the product datasheet before finalizing procurement orders.

Selection Notes

Select this controller when digital monitoring via I2C is required for real-time fault status access. The integrated 12-bit ADC provides accurate current and voltage measurements without external components. Consider the 10-MSOP package size and the 3.15 V to 16.5 V input range for compatibility with existing system power rails.

Part Context

This component belongs to the ADM1176 series of hot swap controllers. It shares functional similarities with the ADM1177 series but distinguishes itself through specific digital monitoring integrations. The device is categorized under Power Management ICs and serves as a critical interface for protecting sensitive loads during insertion or removal events.

Replacement Considerations

The ADM1177-2ARMZ-R7 is a related variant within the same family. Verify if the specific digital monitoring requirements align with the target application before substituting, as feature sets may differ between model variants.
