Overview
The ADM1029ARQ-REEL7 is a dual PWM fan controller and temperature monitoring integrated circuit manufactured by Analog Devices Inc. It operates within a supply voltage range of 3V to 5.5V and supports an operating temperature range from 0°C to 100°C. The device integrates both internal and external sensor capabilities for thermal management. It features alarm outputs and dedicated fan control outputs, designed for active lifecycle applications in system cooling.
Feature Summary
- Dual PWM fan control capability
- Integrated temperature monitoring with internal and external sensor support
- Alarm output functionality
Applications
- System thermal management
- Fan control circuits
- Temperature monitoring systems
Procurement Notes
Verify the component status as active or discontinued through official Analog Devices channels. Confirm the specific package type and pinout compatibility with your design requirements. Ensure that the operating temperature range meets your environmental specifications. Check for any RoHS compliance documentation if required by your manufacturing standards. Validate the supply voltage range against your system power rails.
Selection Notes
Select this component when dual-channel PWM fan control is required alongside precise temperature monitoring. Consider the 3V to 5.5V supply range for compatibility with standard logic levels. Evaluate the need for both internal and external sensor inputs for comprehensive thermal oversight. Assess the alarm output requirements for system safety mechanisms. Compare performance against single-channel alternatives if only one fan needs control.
Part Context
This part belongs to the thermal management category of integrated circuits. It is specifically designed for managing cooling systems in electronic devices. The dual PWM feature allows for independent control of two fans. Temperature monitoring functions ensure safe operating conditions. The component is intended for use in environments requiring active thermal regulation.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided data. Consult Analog Devices for potential cross-references or newer revisions. Verify functional equivalence before substitution.
