The MC33689DWB is an H-Bridge integrated circuit dedicated to the needs of motor and solenoid control. It is designed to provide customers with a single package solution to all their DC motor and solenoid, or valve control needs. The device is particularly suitable for applications that have PWM inputs as well as an On/Off signal and an EmergencyStop signal.

The MC33689DWB has a number of features that make it particularly suitable for these sorts of applications. Most prominently, the device is designed to be used in a brushless motor drive and provides dual single-ended outputs. This allows for the control of two independent motors without having to use a second chip. In addition, the device also includes a slew rate controller which limits the rate at which voltage is applied to the motor, reducing motor and motor driver stress, increasing efficiency and improving motor speed accuracy. The device also includes a range of configurable protection functions, including current limit, thermal shutdown and under voltage protection.

The main advantages that the MC33689DWB offers over other DC motor and solenoid control ICs is its versatility. The device is designed with 4 DC motor and solenoid control modes, allowing for a wide range of applications including speed and torque control, direction control, and braking. In addition, the device also includes configurable digital input/outputs, allowing for a range of additional features such as motor direction control, feedback and over current protection.

The MC33689DWB is ideal for a wide range of applications, from automotive body and chassis management to home goods and accessories. It is also suitable for a wide range of industrial applications such as solenoid valves and contactors, industrial automation, and robotics.

The device is designed to be easy to configure with a number of different input and output options. This allows for a range of customisations based on individual applications. The MC33689DWB provides a full bridge H-bridge drive and PWM inputs, followed by control logic, current sensing and internal protection circuitry.

In H-bridge mode, the MC33689DWB drives two independent DC motors and solenoids in either direction. When used in PWM mode, the device will convert the PWM signal into a voltage or current proportional to the duty cycle. This allows the device to be configured to control the speed, torque and direction of the motor, as well as the current being applied to the motor.

The device also includes a range of protection features to protect both the motor and the device itself. These features include a maximum current limit, a Short Circuit Protection, a Thermal Shutdown, Under Voltage Shutdown and a Current Shutoff. The device also includes an ADC for monitoring the motor current.

In summary, the MC33689DWB is a highly versatile IC, offering a range of features and applications that make it the ideal choice for a wide range of motor control and solenoid control applications. Its versatility and configurability make it suitable for a wide range of industries and applications, making it a valuable and reliable option for many users.
