TC646VOA713

Overview

The TC646VOA713 is a PWM fan controller manufactured by Microchip Technology, designed for motor and motion control applications. It operates within a supply voltage range of 3 V to 5.5 V and draws a typical operating supply current of 1 mA. The device supports surface-mount installation in an SOIC-8 package and functions reliably across an ambient temperature range from 0°C to +85°C. This component integrates shutdown and fault detection capabilities, making it suitable for managing cooling systems where efficient power management and operational safety are required.

Feature Summary

• Integrates dedicated shutdown and fault detection mechanisms for enhanced system protection
• Optimized for low-power operation with minimal quiescent current consumption
• Supports standard CMOS/TTL logic input compatibility for easy interface integration

Applications

• PWM fan speed control in computer and server cooling systems
• Motor control circuits requiring fault monitoring
• Industrial equipment thermal management subsystems

Procurement Notes

Verify the specific suffix '713' indicates the reel packaging configuration when ordering. Confirm that the SOIC-8 package variant matches your PCB footprint requirements. Ensure the 0°C to +85°C industrial temperature range aligns with your environmental specifications. Cross-reference the datasheet for humidity sensitivity handling procedures during assembly.

Selection Notes

Select this component when a compact, low-current fan controller with built-in fault detection is required. The SOIC-8 package offers a balance between pin count and board space efficiency. Consider the 3 V to 5.5 V supply range compatibility with your system's logic levels. Evaluate the thermal performance within the specified operating temperature limits for your enclosure design.

Part Context

This part belongs to the TC646 series of fan controllers from Microchip Technology. The series focuses on providing reliable PWM control with integrated safety features. The 'V' suffix typically denotes the commercial/industrial temperature grade, while 'OA' specifies the SOIC-8 package type. The '713' suffix identifies the specific tape and reel quantity configuration.

Replacement Considerations

Check the TC646VUA for MSOP-8 package compatibility if space constraints differ. Verify functional equivalence regarding shutdown and fault detection features before substitution.
