TC642VOA

Overview

The TC642VOA 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 features a quiescent current of 500 uA. The device provides an output current capability of 5 mA and functions across a temperature range from 0°C to +85°C. It utilizes a PDIP-8 through-hole package configuration.

Feature Summary

• Integrated fault detection capabilities for enhanced system reliability
• Low power consumption suitable for battery-operated devices
• Designed specifically for fan control and motion applications

Applications

• Fan speed control in consumer electronics
• Motion control systems requiring low-power operation
• Ignition controllers with fault detection needs

Procurement Notes

Verify the specific suffix 'V' indicates the PDIP-8 through-hole package variant when ordering. Confirm that the component is currently active and not subject to End-of-Life notices, as availability may vary. Ensure compatibility with existing PCB footprints designed for standard DIP-8 configurations before finalizing procurement plans.

Selection Notes

Select this component for designs requiring simple fan control with integrated fault monitoring. Consider the 500 uA quiescent current for power-sensitive applications. The PDIP-8 package suits prototyping or high-reliability through-hole manufacturing processes compared to surface-mount alternatives.

Part Context

This part belongs to the TC642 series of motor and motion controllers. It complements other variants like the TC642BEOA, which offers similar functionality but in a SOIC-8 surface-mount package with extended temperature ranges. The series focuses on providing efficient drive solutions for small motors.

Replacement Considerations

• TC642VPA (Same series, PDIP-8 package)
