Overview
The TC648BEOA713 is a PWM fan speed controller manufactured by Microchip Technology. It operates within a supply voltage range of 3 V to 5.5 V and draws a maximum operating supply current of 0.4 mA. The device supports one fan and utilizes pulse-width modulation for control. It features system shutdown capability but lacks over-temperature alert functionality. The component is designed for surface mount installation in an SOIC-8 package with dimensions of 4.9 mm length, 3.9 mm width, and a minimum height of 1.25 mm. It functions reliably between -40 °C and 85 °C.
Feature Summary
- Implements PWM control method for precise fan speed regulation
- Provides system shutdown protection mechanism
- Supports single fan configuration
- Designed for surface mount technology integration
Applications
- Fan speed control in electronic systems
- Motor driver applications requiring shutdown features
- Temperature-controlled cooling solutions
Procurement Notes
Verify the active status and end-of-life notifications directly with Microchip Technology or authorized distributors before procurement. Confirm that the SOIC-8 package matches the target PCB footprint. Ensure compliance with RoHS standards if required by the specific application environment. Check for any recent product change notifications affecting the component specifications or manufacturing location.
Selection Notes
Select this component when a single-fan PWM controller with system shutdown is required. Consider the 3 V to 5.5 V supply range compatibility with the target system power rails. Evaluate the need for over-temperature alerts; if such alerts are necessary, alternative models within the series may be more suitable. Verify the surface mount package constraints against the design layout.
Part Context
This part belongs to the TC648B series of fan controllers from Microchip Technology. It is categorized under PMIC and motor drivers. The series includes variants with different packages and features, such as over-temperature alerts. This specific model focuses on basic PWM control and shutdown functionality without thermal monitoring outputs.
Replacement Considerations
Direct substitutes include TC648BEUA and TC648VOA. Parameter-equivalent options are TC642EUA713, TC646EUA713, TC647EUATR, and TC649EUATR. Verify pinout and feature compatibility before substitution.
