Working Principles

The MC33025DWR2 operates as a closed-loop motor controller. It uses an error amplifier to compare the actual motor current with a reference value. The error signal is then fed into a pulse-width modulation (PWM) circuit, which controls the output driver stage. The PWM frequency can be adjusted using external timing components. The IC also incorporates various protection features such as overcurrent detection, undervoltage lockout, and overtemperature shutdown.
