Overview
The EMC2301-1-ACZL-TR is a single-channel, RPM-based PWM fan controller manufactured by Microchip Technology. Designed for thermal management in electronic systems, it regulates fan speed by monitoring rotational feedback to maintain stable airflow. The device operates within a supply voltage range of 2.7V to 5.5V and supports I2C interface communication for configuration. It features an MSOP-8 package with dimensions of 3x3mm and a height of 0.95mm, suitable for space-constrained applications requiring precise cooling control.
Feature Summary
- Implements RPM-based closed-loop control for accurate fan speed regulation
- Supports I2C serial interface for system integration and configuration
- Provides hardware thermal shutdown protection for operational safety
Applications
- Server and storage system cooling management
- Industrial equipment thermal regulation
- Consumer electronics heat dissipation control
Procurement Notes
Verify the complete part number including suffixes against official Microchip documentation to ensure correct package type and tape/reel specifications. Confirm RoHS compliance status and lead times directly with authorized distributors or the manufacturer prior to ordering. Ensure design compatibility with I2C bus requirements and voltage levels specified in the datasheet.
Selection Notes
Select this component when single-fan RPM-based control is required. Compare with EMC2302 for dual-channel needs or EMC2303 for multiple fan configurations. Consider package availability and operating temperature range relative to the target application environment. Verify I2C address settings if multiple controllers are used on the same bus.
Part Context
This component belongs to the EMC23xx series of fan controllers from Microchip Technology, originally developed by SMSC Corporation. The series includes variants for single, dual, and multiple fan channels. The EMC2301 specifically targets single-channel applications, offering a balance of performance and cost for standard cooling solutions in embedded systems.
Replacement Considerations
Direct substitutes include EMC2301 variants with different packaging or tape options. For multi-channel requirements, consider EMC2302 or EMC2303. Cross-reference with EMC2101 for similar functionality with additional features. Verify pinout compatibility and software register mapping before substitution.
