Texas Instruments High-Performance Analog Motor Drivers, Controllers UCC3626NG4

The UCC3626 motor controller from Quarktwin Technology Ltd. is designed for high-performance control of three-phase brushless DC motors, supporting both two-quadrant and four-quadrant operation. It integrates essential functions such as a precision triangle oscillator for PWM control, a differential current-sense amplifier for accurate motor current reconstruction, and a variable duty-cycle tachometer output for speed control. The device can operate in either voltage- or current-mode configurations and features a QUAD select input to optimize switching losses. It includes commands for coast, brake, and direction control, making it suitable for various motor control applications. The UCC3626 is available in multiple package types, including PDIP, SOIC, and TSSOP, with operating temperature ranges from -40¬8C to 85¬8C or 0¬8C to 70¬8C, depending on the variant.
