Overview
The ADM1029ARQZ is a thermal management integrated circuit manufactured by onsemi, housed in a 24-pin QSOP package. It functions as a digital serial temperature sensor and fan controller designed for microprocessor-based systems. The device integrates an internal temperature sensor with external sensing capabilities, providing precise thermal monitoring. It features a digital serial interface for communication and includes built-in alarm outputs to signal over-temperature conditions. The component operates within a standard commercial temperature range and supports low-power standby modes.
Feature Summary
- Integrates digital serial interface for system communication
- Provides combined internal and external temperature sensing
- Includes programmable fan control logic
- Features dedicated hardware alarm outputs
Applications
- Microprocessor thermal monitoring
- System fan speed control
- Over-temperature protection circuits
Procurement Notes
Verify the specific suffix R7 indicates reel packaging when sourcing. Confirm current availability status as distribution channels may list this part as obsolete or discontinued. Ensure the QSOP-24 package matches the target PCB footprint requirements before procurement.
Selection Notes
Select this component for applications requiring integrated thermal sensing and fan regulation via a serial bus. Compare against the ADM1030 if SMBus compatibility is required instead of the proprietary serial interface. Verify that the 24-pin QSOP form factor fits the design constraints compared to smaller packages.
Part Context
This part belongs to the ADM1029 series of thermal management ICs originally developed by Analog Devices and later acquired by onsemi. It serves as a specialized solution for managing heat dissipation in computing hardware. The series typically pairs with other power management components to create complete thermal control subsystems.
Replacement Considerations
Check for ADM1029 variants with different suffixes for packaging changes. Evaluate ADM1030 for similar functionality with SMBus interface compatibility.
