TC642VPA

Overview

The TC642VPA 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 consumes a typical operating current of 500 µA. The device features an output current capability of 5 mA and functions reliably across a temperature range from 0°C to +85°C. It is housed in an 8-pin PDIP package with through-hole mounting capabilities.

Feature Summary

• Integrated fault detection circuitry for monitoring system status
• Optimized for low power consumption in fan control applications
• Compatible with standard CMOS and TTL logic inputs

Applications

• Fan speed control systems
• Motor driver interfaces
• Ignition controller circuits

Procurement Notes

Verify the specific ordering suffix to ensure the correct package type and temperature rating match the design requirements. Confirm RoHS compliance status through official documentation before procurement. Cross-reference the manufacturer part number with distributor catalogs to avoid substitution errors. Ensure the through-hole packaging aligns with the PCB layout specifications.

Selection Notes

Select this component when a dedicated fan controller with fault detection is required. Consider the 5 mA output drive strength for direct fan interface needs. Evaluate the 3 V to 5.5 V supply range against the system power architecture. The PDIP-8 package suits prototyping and through-hole manufacturing processes.
