Brushless Motor Control

BLDC Motor Control with Z8 Encore!® MC Microcontrollers

Z8FMC16100 Series Flash Microcontrollers

Optimized for motor control applications, these microcontrollers support the control of single and multiphase motors. They are ideal for sensor or sensor less BLDC motor applications such as high velocity cooling fan sand fan trays, large and small appliances, HVAC, power tools, and personal care devices.


The Z8FMC16100 MCU features a flexible pulse width modulator (PWM) module with three complementary pairs or six independent PWM outputs supporting programmable dead-band and fault protection trip input. These provide multiphase control capability for a variety of motor types and ensure safe operation of the motor by providing Pulse-by-Pulse or latched fast shutdown of the PWM pins during fault condition. The ADC has a 2.15µs conversion time and can be triggered automatically by the PWM module reducing interrupt rates and jitter for back EMF or current measurements. Time stamps are automatically captured up on ADC initiation.
