Overview
The TC642EUA is a FanSense™ PWM fan controller manufactured by Microchip Technology. It operates within a supply voltage range of 3V to 5.5V and functions as a low-side pre-driver for brushless DC (BLDC) motors. The device is housed in an 8-MSOP package with surface-mount installation. It supports an operating temperature range from -40°C to +85°C.
Feature Summary
- Integrates FanSense technology for automatic fault detection without requiring additional sensors
- Provides pulse width modulation output drive for efficient speed control
- Eliminates the need for software overhead through hardware-based operation
Applications
- Fan speed control in electronic equipment
- Brushless DC motor driver applications
- Thermal management systems requiring fault detection
Procurement Notes
Verify the specific suffix against official Microchip documentation to confirm package type and availability status. Ensure compatibility with system voltage requirements and thermal limits before integration. Confirm RoHS compliance and moisture sensitivity levels via the current datasheet revision.
Selection Notes
Select this component for applications requiring integrated temperature sensing and fan control without software complexity. Consider the 8-MSOP package constraints and the specific low-side output configuration. Evaluate the FanSense feature benefits against alternative solutions requiring external sensors.
Part Context
This part belongs to the TC642 series, which includes variants like TC642BEUA and TC642EUA713. These components are categorized under PMIC and Motor Controllers. The series focuses on cost-effective, hardware-based fan control solutions for modern electronics.
Replacement Considerations
TC642EUA713 is listed as a direct substitute. TC642BEUA is noted as parameter equivalent. Verify pinout and functional equivalence with official Microchip resources before substitution.
