  • Low-Cost DC Motor Speed Control with CMOS ICs
    by the TC4469. Two low-cost CMOS ICs manage a 12 VDC, current-limited speed. In the lower rail devices, a small series resistor helps prevent gate. control circuit for DC brush motors. The circuit design (see. oscillation and slows transition time, helping the upper device to. Figure 1) uses PWM (pulse width
  • Intelligent Remote Positioner
    The excellent cost/performance ratio of the PIC16C5X makes it well suited as a low-cost proportional D.C. actuator controller. This application note depicts a design for a remote intelligent positioning system using a D.C. motor (up to 1/3 hp) run from 12V to 24V. The position accuracy is one
  • Software PID Control of an Inverted Pendulum Using the PIC16F684
    of three main parts: the base platform, the pendulum and the controller board. The base platform is a 3-point platform, 2 wheels (one of which is geared and attached to a DC motor) and an audio jack. When the DC motor is turned on, the base platform will rotate around in a circle with the center
  • MSK4225 Closed Loop Controller
    The MSK4225 is a MOSFET H bridge with internal gate drive and a PWM. generator, all in one convenient package. This configuration can be used to control a. variety of loads, such as a brushed DC motor or a voice coil. Because of the internal. PWM generator, all the user needs to do is provide
  • Linear Voltage Fan Speed Control Using Microchip's TC64X Family
    on or completely off. This efficient control methodology affords a very wide speed control range (typically 10% to 100% of full speed) because the fan motor is exposed to its full-rated voltage during the active portion of the PWM cycle. PWM control works with standard, two-wire Brushless DC (BDC) fans
