TC642EOA713

Overview

The TC642EOA713 is a FanSense™ series motor driver integrated circuit manufactured by Microchip Technology. It operates within a supply voltage range of 3V to 5.5V and is housed in an 8-SOIC package with a width of 3.90mm. Designed for brushless DC (BLDC) motors, this component functions as a speed controller featuring a parallel interface and low-side pre-driver output configuration. The device supports surface mount installation and maintains operational reliability across a temperature range of -40°C to +85°C.

Feature Summary

• Integrated speed control functionality specifically engineered for brushless DC motor applications
• Low-side pre-driver output configuration for direct motor drive interfacing
• Parallel interface compatibility for simplified system integration

Applications

• Fan controllers
• Brushless DC motor speed regulation systems

Procurement Notes

Verify the specific suffix '713' corresponds to the tape and reel packaging variant when ordering. Confirm that the 8-SOIC footprint matches the target PCB layout dimensions. Ensure the design accommodates the specified 3V to 5.5V supply voltage constraints. Check for RoHS3 compliance requirements against project specifications.

Selection Notes

Select this component when designing BLDC fan control circuits requiring a dedicated speed controller with low-side driving capabilities. The 8-SOIC package offers a compact solution for space-constrained designs. Consider the operating temperature range and supply voltage limits during thermal and power budget analysis.

Part Context
