　　HOLTEK HT66FM5230 DC inverter BLDC dedicated MCU

　　Holtek has launched the DC-FAN Flash version of the MCU HT66FM5230 for single-phase/three-phase brushless DC motor control. The HT66FM5230 supports three-phase BLDC motor applications and single-phase BLDC motor applications. The control solution can fully support square wave and sine wave solutions, of which square wave control can support Hall Sensor and Hall Sensor-less solutions. It is equipped with 3 pairs of 10-bit PWM pulse width modulation control outputs, with complementary, dead time PWM outputs, and Polarity IO polarity adjustment. In view of the fact that the control of brushless DC motors requires a feedback signal to detect over-current and over-voltage protection mechanisms, the HT66FM5230 integrates the OCP circuit with the integrated use of ADC to control the smooth operation of the motor and achieve the function of protecting the DC motor.

　　The HT66FM5230 has 2Kx16 Flash Program ROM, 256 Byte Data RAM, 32 Byte Data EEPROM, an operating voltage of 4.5V~5.5V, a system frequency of 20MHz, a built-in precision RC Oscillator (HIRC), a built-in 6-channel 10-bit fast ADC, a 10-bit STM Timer that can be used for applications such as PWM speed control interface, a 10-bit CTM Timer and a 16-bit CTM Timer, a 16-bit CAPTURE Timer that can be used for constant speed loop monitoring, a PWM Timer that can be used for motor control 6-channel PWM current modulation (supporting 1 PWM Period and 3 PWM Duty), an I2C communication interface, LVD and LVR are used to detect system voltage. If the system voltage is lower than the LVR value, the system will reset to avoid the unstable state that may be caused by the system operating voltage being lower than the operating voltage. An OCP circuit is used for motor protection, and 3 built-in comparators can support square wave Sensorless control.

　　The HT66FM5230 is available in 16NSOP and 20SSOP packages and is very suitable for DC-FAN single-phase/three-phase brushless DC motor fan applications. Like other 8-bit MCUs from Holtek, this product has industrial specifications and high noise immunity.
