The EVAL-ADM1281-AZ evaluation board supplied and procured by Mingjiada Electronics serves as a fully functional platform for developing and evaluating the ADI ADM1281 hot-swap controller. Designed specifically for power monitoring and control in servers, telecommunications, and data communications equipment, it enables engineers to efficiently undertake prototyping and performance validation.
Core Product Features
The EVAL-ADM1281-AZ evaluation board combines high flexibility with robust diagnostic capabilities. Key features include:
Core Configuration: Pre-assembled and tested 12V/73A hot-swap design capable of driving 3mF output capacitors.
Layout and Thermal Management: Compact single-board layout optimises thermal dissipation for critical components along the power path.
Design Flexibility: Provides five sensing resistor slots and six multi-package field-effect transistor slots, supporting component parallelisation for high-current applications.
Status Diagnostics: Seven on-board LEDs directly indicate critical information including power status, faults, and IC condition.
Precision measurement: Integrated AD7291 SAR ADC enables real-time I²C bus reading of voltage, ambient board temperature and other parameters.
Communication and control: Supports I²C communication, PMBus protocol and multi-board cascading for simplified system integration and control.
Core Controller: ADM1281
The evaluation board centres on ADI's ADM1281 hot-swap controller. This chip is specifically engineered to manage the secure insertion and removal of circuit boards on live backplanes, featuring:
Precision Monitoring: An integrated 12-bit analogue-to-digital converter (ADC) reads and reports current, voltage, power, and temperature data with ±0.3% accuracy.
Rapid Protection: Features an exceptionally short 290-nanosecond (ns) short-circuit response time, enabling swift fault isolation and system protection.
Programmable Capabilities: Parameters such as current limit, under-voltage (UV)/over-voltage (OV) thresholds are programmable. The current limit defaults to 20mV and can be adjusted via resistors within the 5mV to 25mV range.
Typical Application Scenarios
This evaluation board is primarily deployed in applications demanding exceptional power supply stability and reliability:
Server Power Management: Ensures safety during hot-swap maintenance of components like hard drive backplanes and fan modules.
Telecom and Data Communication Equipment: Provides stable power access and control for line cards in routers and switches.
Power Monitoring and Budgeting: Precisely monitors system power consumption for efficient power allocation and budget management.
