The THMC45 is a dc brushless motor (BLM) driver and control device designed for use with low-voltage (5 V or 3.3 V) dc cooling fans having two-phase motors with a single-winding stator.
The device includes a high-efficiency H-bridge pulse width modulation (PWM) drive topology with integrated MOS high-side and low-side drivers, plus a PWM control input stage to provide the industry’s first efficient speed control solution inside low-voltage dc cooling fans.
This solution eliminates the need for any power drive components on the main system board, reducing printed-circuit board (PCB) component count, PCB space, and assembly time.
