Overview
The ADM1178-1ARMZ-R7 is a hot swap voltage controller manufactured by Analog Devices Inc. It operates within an input voltage range of 3.15 V to 16.5 V and features adjustable current limiting. The device includes power fail detection and auto-retry functionality, controlled via an ON pin. It consumes 1.7 mA of operating supply current and supports I2C communication. Designed for surface mount installation in MSOP-10 packages, it functions reliably across temperatures from -40°C to +85°C.
Feature Summary
- Integrates auto-retry logic for automatic recovery after fault conditions
- Supports programmable current limiting through external components
- Includes dedicated power fail detection capability
- Enables system control via I2C interface
Applications
- Hot swap circuit protection in server backplanes
- Power distribution units requiring controlled insertion
- Industrial equipment with modular power architectures
- Telecommunications infrastructure power systems
Procurement Notes
Verify the specific suffix R7 corresponds to reel packaging requirements. Confirm RoHS compliance status through official documentation before integration. Ensure the MSOP-10 footprint matches the target PCB layout. Validate that the 3.15 V minimum operating voltage aligns with the system supply rails. Check for any recent product change notices affecting availability or specifications.
Selection Notes
Select this component when precise hot swap sequencing and current monitoring are required. The adjustable current limit allows customization for various load profiles. The I2C interface enables remote configuration and status reporting. Consider the MSOP-10 package size for space-constrained designs. Verify thermal performance under maximum load conditions within the specified temperature range.
Part Context
This part belongs to the ADM1178 series of hot swap controllers. It is designed for applications requiring controlled power insertion and removal. The device integrates essential protection features into a compact form factor. It serves as a critical component in managing power delivery to sensitive electronic loads.
Replacement Considerations
The ADM1177-1ARMZ-R7 is a related controller in the same family. Verify functional compatibility regarding pinout and control interfaces before substitution.
