The MC33926ESR2 is a dual full-bridge Motor Driver, a device designed to control the speed and direction of a brushed DC electric motor. It is a member of the Texas Instruments MC33926 family of integrated motor driver products. Texas Instruments is a global semiconductor company that designs, manufactures, and sells analog and embedded processing chips, digital memory chips, optoelectronic components, power management devices, and digital signal processors. The MC33926 family of products are designed to drive small electric motors between 8.0V up to 40V, providing output current up to 2A with a thermally sensitive on-chip thermal protection. As a full bridge motor driver, the MC33926ESR2 is a “gated H-bridge” with four internal power MOSFETs configured as an inverter circuit. This configuration of four MOSFETs enables the device to control the direction and speed of a DC brushed motor with external input signals.

The MC33926ESR2 is a stand-alone, self-contained motor driver with a built-in microcontroller, allowing the user to set the desired function and device parameters with simple input commands. The device is designed to be programmed and controlled via a serial or a parallel connection to the host system, such as a microcontroller. The built-in microcontroller implements the user\'s desired functions, such as controlling the speed and direction of the electric motor, as well as regargding and resetting the device after system reset.

The MC33926ESR2 also includes standard protection features for motor load protection and over temperature, along with a thermal switch for overload detection. The overload protection feature is controlled by the on-board microcontroller, monitoring the motor current and taking corrective action when needed. The over temperature protection monitors the die temperature of the motor driver and shuts it down in the event of a thermal runaway.

The MC33926ESR2 is a versatile and cost-effective motor driver for small electric motors. It can be used for applications such as automotive power steering, hand-held and robotic devices, industrial automation, and personal mobility vehicles. The MC33926ESR2 is a simple and cost-effective solution for driving small DC electric motors with a high degree of performance and accuracy.
