It can be used for automotive, industrial, and commercial applications. In motor control applications, the MIC23030-FYMT-TR can be used to drive the power FET in brushless DC (BLDC) motor control systems and in variable speed DC brush motor drives. In IoT applications, it can be used to power DC fan, DC blower, and other DC motor-driven products. In power tool applications, it can be used for variable speed motor control of power tools.

Working Principle

The MIC23030-FYMT-TR operates on two different principles: pulse width modulation (PWM) and pulse frequency modulation (PFM). PWM is the process of controlling the duty cycle of a pulse train that is applied to the motor’s windings. The frequency of the pulses determines the speed of the motor. PFM is the process of controlling the frequency of the pulse train that is applied to the motor’s windings. The higher the frequency of the pulses, the faster the motor will spin. Both PWM and PFM are commonly used for motor control applications.

The MIC23030-FYMT-TR operates by detecting the voltage level at its output and adjusting the output voltage accordingly. The internal circuitry of the device adjusts the duty cycle based on the voltage level of the output. When the output voltage rises above the set point, the duty cycle is reduced, and when it drops below the set point, the duty cycle is increased. By adjusting the duty cycle in this way, the MIC23030-FYMT-TR is able to maintain the output voltage at the set point.

Conclusion

The MIC23030-FYMT-TR is a fast-mode switching regulator driver with a logic-level control interface. It belongs to the category of PMIC – Voltage Regulators – DC DC Switching Regulators. This integrated circuit can be used for a variety of applications including motor control, IoT, power tools, and motor driven products. Its features include an operating frequency range from 800kHz to 2Mhz, integrated bootstrap voltage generation circuit, PFM and PWM modes, undervoltage lockout, overvoltage lockout, and protection from destructive shoot-through conditions.
