A8904SLBTR belongs to PMIC (Power Management IC), motor driver and controller. It is a versatile dual-half-bridge motor driver designed specifically to drive a wide variety of inductive loads such as large and small DC motors, stepper motors, relays and solenoids, but not limited to these.

Performance Feature

• Two supply voltages for independent control of upper and lower branches
• Internal 10V reference voltage
• 500mA low-side output current
• Operates with high power conversion efficiency

Applications

A8904SLBTR is widely used in a variety of industrial, automotive and consumer production applications, such as sweeping machines, slideway, conveyor belt, robot, electric tools, home security, automatic curtains, electric locks, transplanter and plotter.

Pin Functions

A8904SLBTR has two operating pins. The first is the EN pin, which is used to enable or disable the motor driver. The second is the PWM pin, which can be used to control the motor speed and direction. In addition, there are several other pins that can be used to configure the motor driver. These include the Input Voltage pins, the Output Voltage pins, the Clock pins and the Enable Pins.

Working Principle

A8904SLBTR works by using a PWM signal to control the voltage that is provided to the motor. A PWM signal can range from 0 to 100%. When the duty cycle is 0%, the motor will not move, and when the duty cycle is 100%, the motor will turn at its maximum speed. By changing the duty cycle, the speed and direction of the motor can be controlled. The PWM signal can be generated by a microcontroller, such as an Arduino or a Raspberry Pi.

The motor driver also needs a power source to be able to control the motor. The power source can either be an external supply, such as a battery, or it can be supplied by the A8904SLBTR itself. The A8904SLBTR is able to provide up to 500mA of current to drive the motor.

Conclusion

A8904SLBTR is a versatile dual-half-bridge motor driver that is designed specifically for driving a wide variety of inductive loads. It can be used in a variety of industrial, automotive and consumer production applications and is controlled using a PWM signal from a microcontroller. It can provide up to 500mA of current, which makes it ideal for driving larger DC motors or stepper motors.
