TC642CPA

Overview

The TC642CPA is a fan controller and driver manufactured by Microchip Technology, designed for brushless DC (BLDC) motor applications. It operates within a supply voltage range of 3 V to 5.5 V and features a low operating supply current of 500 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 standard commercial temperature range from 0°C to +70°C.

Feature Summary

• Integrated speed control functionality for brushless DC motors
• Built-in fault detection capabilities for system protection
• Low power consumption suitable for battery-operated devices

Applications

• Fan speed control systems
• Brushless DC motor drivers
• Battery-powered cooling solutions

Procurement Notes

Verify the specific package type and pinout configuration against the official datasheet before integration. Confirm that the operating voltage and current requirements align with the target application's power budget. Ensure environmental conditions remain within the specified commercial temperature limits during operation.

Selection Notes

Select this component when a dedicated fan controller with integrated drive capability is required. Consider the PDIP-8 package for through-hole mounting needs. Evaluate the 5 mA output current limit to ensure it meets the load requirements of the intended BLDC motor or fan assembly.

Part Context

The TC642CPA belongs to the TC642 series of fan controllers and drivers. It is part of Microchip's portfolio of power management ICs focused on motor control applications. This specific variant utilizes a PDIP-8 package, distinguishing it from surface-mount alternatives like the TC642EUA which uses an MSOP package.

Replacement Considerations

Direct substitutes include other variants within the TC642 family, such as TC642EUA, provided the package difference is acceptable.
