ADM1030ARQZ-REEL7

Overview

The ADM1030ARQZ-REEL7 is an ACPI-compliant intelligent temperature monitor and PWM fan controller designed for microprocessor-based systems. It features a two-channel digital thermometer with ±1°C accuracy on the remote channel and 0.125°C resolution. The device includes a dedicated pulsewidth modulation (PWM) output for fan speed control, tachometer input for RPM measurement, and analog input capability for 2-wire fans. Communication occurs via a 2-wire System Management Bus (SMBus) with Alert Response Address support. Operating voltage ranges from 3 V to 5.5 V.

Feature Summary

• Integrates dual temperature sensing channels with high-resolution local and remote measurements.
• Provides automatic fan speed regulation through programmable PWM outputs independent of CPU intervention.
• Supports SMBus communication with configurable addressing and alert response capabilities.
• Includes fail-safe thermal protection outputs and fan fault detection mechanisms.

Applications

• Notebook PCs
• Network Servers
• Personal Computers
• Telecommunications Equipment
