TC648BEPA

Overview

The TC648BEPA is a fan controller manufactured by Microchip Technology, designed for brushless DC motor applications. It operates within a supply voltage range of 3 V to 5.5 V and draws a typical operating supply current of 200 uA. The device provides an output current capability of 5 mA and supports through-hole installation in an 8-pin PDIP package. It functions effectively across a wide temperature range from -40°C to +85°C. Key features include shutdown and over-temperature alert capabilities, making it suitable for thermal management systems requiring reliable low-power control.

Feature Summary

• Integrated shutdown and over-temperature alert functionality for system protection
• Low power consumption with 200 uA operating supply current
• Designed specifically for fan and brushless DC motor control applications

Applications

• Fan speed control in electronic equipment
• Thermal management systems with over-temperature monitoring
• Brushless DC motor driver interfaces

Procurement Notes

Verify component authenticity due to End-of-Life status. Confirm package integrity upon receipt as the PDIP-8 housing may be subject to handling variations during legacy distribution. Cross-reference datasheet revisions to ensure compatibility with existing design specifications before final procurement integration.

Selection Notes

Select this component when through-hole mounting is required for fan control circuits. The 8-pin PDIP format suits prototyping or high-reliability assemblies where surface mount options are unsuitable. Ensure design accommodates the 3V to 5.5V supply range and utilizes the available alert pins for thermal safety compliance.

Part Context

Part of the TC648B series within Microchip's FanSense portfolio. This specific variant distinguishes itself via the PDIP-8 through-hole package, contrasting with MSOP or TSSOP surface-mount alternatives like the TC648BEUA. It shares core electrical characteristics with the family while offering distinct mechanical mounting properties for industrial or legacy board designs.

Replacement Considerations

Publicly confirmed substitute part numbers are not explicitly listed in the provided documentation. Designers should evaluate pin-compatible alternatives within the same manufacturer family or consult official discontinuation notices for recommended migration paths.
