ADT7476ARQZ-R7

Thermal Management Overview

The ADT7476ARQZ-R7 is a board-mount temperature sensor IC manufactured by onsemi, housed in a QSOP-24 surface-mount package. It operates within a temperature range of -40°C to +125°C with a maximum accuracy of 2.5°C. The device features a digital output and supports 4-wire interface communication. Designed for thermal management, it functions as a multi-channel fan controller.

Thermal Management Feature Summary

• Integrates multi-channel fan control capabilities for system cooling management
• Provides digital temperature sensing with specified accuracy limits
• Supports standard serial interface protocols for data communication

Thermal Management Applications

• Motor control systems requiring thermal monitoring
• Motion control applications needing active cooling
• Ignition controllers utilizing fan speed regulation

Thermal Management Procurement Notes

Verify component authenticity through authorized distribution channels due to discontinued status. Confirm package integrity and pin alignment against the QSOP-24 specification. Ensure compatibility with existing 4-wire interface requirements before integration into motor or ignition control designs.

Thermal Management Selection Notes

Select this component when integrated fan control and temperature sensing are required in a single package. Consider the 2.5°C accuracy limit and 4-wire interface constraints. Evaluate suitability for motor, motion, or ignition environments where space-saving integration of thermal management is prioritized over higher precision standalone sensors.

Thermal Management Part Context

This part belongs to the ADT7476 series of hardware monitors and thermal controllers. It is distinct from other ADT variants by its specific packaging and interface configuration. The series targets noise-sensitive and power-sensitive applications requiring active system cooling solutions.

Thermal Management Replacement Considerations

Public confirmed substitute part numbers are not available. Verify functional equivalence with alternative thermal controllers if sourcing new production units.
