Advanced Motor Control Applications
Brushless Fan Control
Need a highly integrated fan controller with a customizable
speed/temperature pro?le? Take a look at Microchip’s
PIC12HV and PIC16HV devices. These devices have a
built-in 5V regulator and on-chip comparator to save system
cost. The rotor position is determined by a Hall-Effect
sensor connected to the on-chip comparator. The Enhanced
Capture Compare PWM (ECCP) Module uses this feedback
information to drive the motor by steering the PWM signal
to the appropriate motor phase. Temperature sensor inputs
can be used to create a unique fan speed pro?le and the
application can provide digital status information to a host
device.
Stepper Motor Control
Do you need exact position control with great holding torque?
If so, then a stepper motor is the best solution. While nearly
every MCU or DSC from Microchip can drive a stepper motor,
some are better suited than others.
