Holtek introduced the Flash version of MCU HT66FM5240 for DC-FAN fans in the field of brushless DC motor control. HT66FM5240 supports three-phase BLDC motor application and single-phase BLDC motor application, and the control scheme can fully support square wave scheme and chord wave scheme, among which square wave control can support Hall Sensor scheme and Sensor-less scheme. It is equipped with three pairs of 10-bit PWM pulse width modulation control outputs, with complementary and Dead Time PWM outputs and polarity adjustment with Polarity IO. In view of the control of brushless DC motor, it is necessary to have a feedback signal to detect overcurrent and overvoltage protection mechanism. HT66FM5240 integrates OCP circuit with ADC, which can control the smooth operation of the motor and achieve the function of protecting the DC motor.
HT66FM5240 has 4K x 16 Flash Program ROM, 256 Byte Data RAM, 64 Byte Data EEPROM, working voltage of 4.5V~5.5V, system frequency of 20MHz, and built-in precision RC Oscillator (HIRC). Built-in 8-channel 12-bit fast ADC, 2 10-bit PTM Timer, 2 16-bit PTM Timer and 1 16-bit CAPTURE Timer can be used for constant speed…

I’d say "deadband" is the more end-user term, and "hysteresis" more of a engineering term. Engineers will understand deadband in this context, but Joe Sixpack or even a electrician installing a thermostat may not understand what "hysteresis" means.
I disagree that these words apply to more complex processes. What is going on in a simple thermostat is exactly hysteresis, which is fine to express as deadband to laymen. You are overthinking this. The more precise meaning of deadband is actually different from hysteresis. A deadband is a region where the system doesn’t…

Unless you are lucky enough to live and work in a tropical location, it’s a pretty safe bet that your application will require additional heating. The enclosures that house your delicate and essential electrical equipme nt need a little extra help staying warm during frigid winter months.
Temperatures as low as negative 60 degrees Fahrenheit are recorded on a regular basis. In fact, most states located in the United States reach lows well below manufacturer’s optimal temperature levels for electrical equipment. When the temperature inside the enclosure increases or decreases it can negatively affect the electrical components within. The optimal operating…
