Aug 20, 2020 · Apex Microtechnology SA306 Low-Cost PWM Brushless Motor Driver ICs are designed to drive three-phase Brushless DC (BLDC) motors. Three independent half-bridges provide over 15 amperes peak output current under microcontroller or DSC control. With PWM control the DC current applied to the motor is sent in square-wave pulses. The width of the pulses is changed to regulate motor speed, the wider the pulse the faster the motor will spin. The pulse width is expressed as a percentage, at 50% the output is a perfect square wave. At 75% the pulse spends 75% of its time HIGH, the rest LOW.

Integrated CMOS control circuitry, and DMOS power device on the same chip, the use of which may constitute a complete motion control system with the main processor, motors and incremental encoders. Nov 03, 2009 · If the voltage reversals are at a high enough frequency, the cycling is unnoticeable. Generally 20kHz is a good choice for PWM frequency because it is well beyond of the dynamic range of motors and just beyond the range of human hearing. For more information on PWM, see Driving a DC Motor using PWM and Pulse Width Modulation. DC Motor Driver Cytron DC Motor Driver Series are easy to use H-bridge motor drivers that amplify the control signal (e.g. PWM, Direction or Potentiometer Input) to drive a motor. Some of them might come with simple protection features.
