ADM1026JST-REEL

Overview

The ADM1026JST-REEL is a complete thermal system management controller manufactured by onsemi. It features up to 19 analog measurement channels, including internal sensors and remote diode inputs, alongside eight fan speed measurement channels and seventeen general-purpose logic I/O pins. The device supports SMBus communication with an integrated 8 kB EEPROM for data storage. Operating within a supply voltage range of 3.0 V to 5.5 V, it provides analog and PWM fan control outputs. The component operates across a temperature range of 0°C to 100°C with an accuracy of ±3°C for the internal sensor.

Feature Summary

Integrates multiple analog measurement channels for comprehensive system parameter monitoring
Provides dedicated hardware interfaces for fan speed measurement and control via PWM or DAC outputs
Includes non-volatile memory for persistent configuration and data retention during power loss
Supports serial system management bus protocols for centralized device addressing and data access

Applications

Network servers and personal computers
Telecommunications equipment
Test equipment and measuring instruments

Procurement Notes

Verify component authenticity through authorized distribution channels. Confirm package integrity upon receipt. Check datasheet revisions for any functional updates. Ensure compatibility with existing system voltage levels before integration. Validate environmental ratings against operational requirements.

Selection Notes

Evaluate channel count requirements against available analog and digital inputs. Consider interface compatibility with existing system controllers. Assess thermal performance needs relative to onboard sensor capabilities. Verify power supply constraints match specified operating ranges. Review memory capacity for necessary data logging functions.

Part Context
