Overview
The ADM1177-1ARMZ-R7 is a single-channel hot swap voltage controller manufactured by Analog Devices Inc. It operates within a supply voltage range of 3.15 V to 16.5 V and draws a typical operating current of 1.7 mA. The device is housed in a 10-MSOP surface-mount package with dimensions of 3.00 mm width. It supports an extended industrial temperature range from -40°C to +85°C. Key programmable features include adjustable current limiting, fault timeout, and turn-on voltage settings.
Feature Summary
- Integrates I2C interface for digital control and status monitoring
- Provides automatic retry functionality following fault conditions
- Includes under-voltage lockout (UVLO) protection mechanisms
Applications
- General purpose hot swap controller applications
- System board insertion and removal protection
- Power distribution unit circuitry
Procurement Notes
Verify the specific suffix R7 indicates reel packaging when sourcing. Confirm the 10-MSOP package type matches your PCB footprint requirements. Ensure the 3.15 V minimum supply voltage aligns with your system rails. Check for availability constraints as stock levels may vary. Validate RoHS compliance documentation prior to final procurement decisions.
Selection Notes
Select this component for designs requiring precise hot swap management with digital feedback. The single-channel configuration suits individual rail protection needs. Consider the 1.7 mA quiescent current for power-sensitive systems. The I2C capability allows for dynamic configuration adjustments during operation. Verify thermal performance within the specified -40°C to +85°C operational envelope.
Part Context
This part belongs to the ADM1177 series of hot swap controllers from Analog Devices. It serves as a general-purpose solution for protecting circuits during live insertion. The device complements other PMIC offerings by providing robust fault handling. It is designed for integration into complex power management architectures requiring reliable switching control.
Replacement Considerations
The ADM1177-2ARMZ-R7 is a related variant within the same family. Verify channel count differences if dual-rail protection is required. Ensure pin compatibility remains consistent across the series before substitution.
