Overview
The TC643VUA is a bipolar PWM fan controller and driver manufactured by Microchip Technology. It operates within a supply voltage range of 2.7 V to 5.5 V and features a shutdown and fault detection capability. The device draws a typical operating supply current of 500 uA and provides an output current of 5 mA. It is housed in an 8-pin MSOP package with a width of 3.00 mm. The component is designed for surface mount installation and functions reliably across a temperature range of 0°C to +85°C.
Feature Summary
- Integrates shutdown and fault detection mechanisms for enhanced system reliability
- Supports bipolar pulse-width modulation (PWM) control for precise fan speed regulation
- Optimized for low power consumption with minimal operating supply current
Applications
- Fan speed control in computer systems
- Thermal management in embedded devices
- Motor driver applications requiring low current outputs
Procurement Notes
Verify the specific datasheet revision and ordering suffixes to ensure compatibility with your design requirements. Confirm moisture sensitivity levels and reflow soldering profiles prior to assembly. Cross-reference the part number with official Microchip Technology documentation to validate authenticity and technical specifications before procurement.
Selection Notes
Select this component when a compact, low-power solution for bipolar PWM fan control is required. The 8-MSOP package suits space-constrained designs. Ensure the application voltage remains within the 2.7 V to 5.5 V range. Consider the 5 mA output current limit when sizing the load. Verify thermal performance within the specified operating temperature range.
Part Context
The TC643VUA belongs to the TC64x series of motor and motion controllers from Microchip Technology. This family focuses on providing integrated solutions for fan and small motor control applications. The device combines control logic with driver capabilities in a single compact package, simplifying circuit design for thermal management systems.
Replacement Considerations
Consult official Microchip Technology substitution guides for verified alternatives. Generic equivalents may not match the specific electrical characteristics or pinout configuration. Validate any substitute against the original datasheet parameters to ensure functional compatibility.
