The MC33926PNB is a Pulse Width Modulated (PWM) motor controller capable of running one motor in both forward and reverse directions. It is designed specifically for applications requiring high-current drive capability and single package integration of motor controls, protection, and I/O. This device is the perfect choice for high-performance motor control applications, such as running one motor with only one IC, while at the same time providing a highly efficient, safe and reliable system.

The MC33926PNB combines high-current Motor Driver ICs with an optimized output stage that ensures an efficient drive current for a given motor load. This combination of two components in a single package makes the MC33926PNB a great choice for applications that require single package integration of motor drive, protection and I/O.

MC33926PNB has comprehensive on-chip protection features,including over current, over voltage and ground fault protection,which protect the MC33926PNB from damage and maintain the operational safety of the circuit.

The MC33926PNB can be applied to various motor driving applications, including variable speed drives, position control, dynamic braking, and motor fault detection. This chip can also be used as part of a subsystem where motor control, protection, and I/O are needed.

The MC33926PNB works by using a Pulse Width Modulation (PWM)input signal to feedback an analog voltage to the motor driver. The PWM signal is generated by an external voltage controlled oscillator (VCO). The amplified PWM signal is sent to the output stage, which converts it into a current that is supplied to the motor. The control voltage, which is generated according to the PWM signal’s duty cycle, determines the speed at which the motor runs. The MC33926PNB supports a PWM frequency range of 2.5 kHz to 20 kHz, making it suitable for use in a wide range of applications.

The main feature of the MC33926PNB is its ability to drive a single-phase brushless DC motor in both forward and reverse directions. The MC33926PNB includes on-chip driver circuits for producing drive voltages to the motor depending on the rotation direction and the available supply voltages. This feature greatly simplifies system control and reduces overall system complexity.

The MC33926PNB can operate with an input voltage range of 4.5 V to 32 V. An on-board switch-mode power conversion circuit provides a regulated 5-V logic supply rail, making it compatible with a wide range of external logic and microcontroller devices. The output current of MC33926PNB is as high as 11 A continuous and 22 A for short duration. An enable and fault signal is also available for diagnostic and protection purposes.

In summary, the MC33926PNB is a motor driver IC that provides both motor drive and protection in a single package. This device is capable of producing both forward and reverse drive current and can operate with an input voltage range of 4.5 V to 32 V. It also has on-chip protection features and a regulated 5-V logic supply rail, making it suitable for various applications.
