TC649VPA

Overview

The TC649VPA 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 a single output capable of sourcing 5 mA and functions at a working frequency of 30 Hz. It is housed in an MSOP-8 surface-mount package and supports installation via SMD/SMT methods. The component is rated for operation between 0°C and +85°C ambient temperature.

Feature Summary

• Integrates shutdown and fault detection capabilities for enhanced system reliability
• Provides low-power operation with minimal quiescent current consumption
• Supports direct interface with fans through dedicated output drivers

Applications

• Fan speed control in electronic equipment
• Motor driver circuits requiring fault monitoring
• Motion control systems with thermal management needs

Procurement Notes

Verify the specific suffix 'VPA' corresponds to the MSOP-8 package and commercial temperature range (0°C to +85°C) as documented in official Microchip datasheets. Confirm RoHS compliance status and moisture sensitivity level requirements prior to integration. Ensure ordering quantities align with tube packaging specifications provided by authorized distributors.

Selection Notes

Select this component when a single-output fan controller with integrated fault detection is required. Compare against other TC649 series variants based on package type and temperature rating. Ensure the 5 mA output current meets load requirements and that the 3 V to 5.5 V supply range matches system power rails.
