Overview
The TC648EUA713 is a PWM 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 shutdown and over-temperature alert capabilities. The device is housed in an 8-MSOP surface-mount package and supports operation across a temperature range of 0°C to +85°C. With a typical operating supply current of 1 mA, it integrates low-side pre-driver outputs for efficient fan control.
Feature Summary
- Integrates shutdown functionality with over-temperature alert monitoring for enhanced system protection.
- Provides dedicated low-side pre-driver outputs optimized for controlling external N-channel MOSFETs.
- Supports pulse-width modulation (PWM) speed control for precise brushless DC fan management.
Applications
- Brushless DC fan speed control systems
- Computer cooling solutions
- Server and network equipment thermal management
Procurement Notes
Verify the specific suffix '713' against official Microchip documentation to confirm reel packaging specifications and moisture sensitivity levels. Ensure compatibility with the required 8-MSOP footprint and validate that the 3V to 5.5V supply range aligns with the target application's power architecture before finalizing procurement.
Selection Notes
Select this component when a compact, low-power solution for BLDC fan control is required. The 8-MSOP package offers space efficiency for dense PCB layouts. Consider the integrated thermal protection features if the application demands robust fault detection without additional discrete components. Verify interface requirements against standard PWM control signals.
Part Context
This part belongs to the TC648 series of fan controllers from Microchip Technology. It is specifically engineered for managing small to medium-sized brushless DC fans in consumer electronics and computing hardware. The series emphasizes low standby current and reliable thermal monitoring to ensure long-term operational stability in enclosed environments.
Replacement Considerations
Direct substitutes include the TC648BEUA713, which shares similar functional characteristics and packaging. Cross-reference datasheets to confirm pinout compatibility and electrical parameter alignment before substitution.
