UCC3626PWTRG4

Overview

The UCC3626PWTRG4 is a three-phase brushless DC motor controller manufactured by Texas Instruments. It operates within a supply voltage range of 11 V to 14.5 V and draws a typical operating supply current of 3 mA. The device provides an output drive current of 120 mA per phase. It functions as a pre-driver for half-bridge configurations, managing commutation and direction control via PWM interfaces. The component is housed in a 28-pin TSSOP package with surface-mount installation. It supports an extended industrial temperature range from -40°C to +85°C.

Feature Summary

• Integrated three-phase BLDC motor control with built-in commutation logic
• PWM interface for external direction and speed management
• Pre-driver stage designed for driving external half-bridge power FETs
• Operates on low supply current suitable for battery-powered applications

Applications

• Brushless DC motor drives in consumer appliances
• Fan and pump control systems requiring precise commutation
• Industrial motion control modules using half-bridge topologies

Procurement Notes

Verify the specific suffix 'G4' indicates lead-free compliance and RoHS status against the manufacturer's official documentation. Confirm that the tape-and-reel packaging matches system automation requirements. Check for any recent product discontinuation notices or lifecycle changes directly from Texas Instruments before finalizing procurement plans.

Selection Notes

Select this component when designing three-phase BLDC systems requiring integrated commutation without external microcontrollers. Ensure the application voltage remains strictly between 11 V and 14.5 V. Verify that the required output drive current of 120 mA is sufficient for the target gate charge of the external MOSFETs at the intended switching frequency.

Part Context

This part belongs to the UCC3626 family of motor controllers. It serves as a specialized solution for simple, cost-effective BLDC applications where discrete logic or complex digital controllers are unnecessary. The device simplifies design by integrating timing and sequencing functions typically handled by separate components.
