TC642BEPA

Overview

The TC642BEPA is a 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 500 uA. The device features an output current capability of 5 mA and supports through-hole installation in an 8-pin PDIP package. It functions effectively across a temperature range from 0°C to +85°C.

Feature Summary

• Integrated fault detection capabilities for system monitoring
• Restart functionality for automated recovery operations
• Low power consumption design suitable for battery or efficiency-critical systems

Applications

• Fan speed control in computer systems
• Motor driver circuits in industrial equipment
• Ignition system controllers

Procurement Notes

Verify component authenticity due to End-of-Life status. Confirm package integrity upon receipt as the PDIP-8 housing may show wear during storage. Check datasheet revisions for any pinout changes before finalizing PCB layouts. Ensure environmental compliance documentation matches project requirements.

Selection Notes

Select this part when through-hole mounting is required for robust mechanical connections. Consider the 500 uA quiescent current for low-power designs. Evaluate the 5 mA drive strength against load requirements. Compare with surface-mount alternatives like TC642EUA if space constraints dictate SMD packaging.

Part Context

Part of the TC642 family of fan controllers. Shares functional similarities with TC642VPA but differs in package type. Related evaluation boards include TC642EV. Manufactured under Microchip's PMIC portfolio for thermal management solutions.

Replacement Considerations

TC642VPA offers identical electrical performance in a different package configuration.
