The integrated motor controller and driver can control DC or AC motors with a wide range of power sources. In this article, we will look at the working principle and application field of SLA7076MPRT.

What Is SLA7076MPRT?

The SLA7076MPRT is a single-chip bi-directional motor control IC with both motor drive and control functions that provide complete control for DC and AC motors. The device combines an H-bridge type driver with a microcontroller, making it ideal for applications such as motor control in home appliances, industrial machines, and other equipment. The motor driver has an excellent operating frequency range of up to 15kHz, and it can be used to directly drive inductive loads. Additionally, the device is protected against over-temperature, under-voltage, and overcurrent.

Working Principle of SLA7076MPRT

The SLA7076MPRT includes an 8-bit microcontroller, a comparator circuit, a PWM generator and H-bridge driver circuit. The microcontroller is used to process input signals from the external environment and to control the power stage circuit. The comparator circuit compares the voltage of the terminal signal of the microcontroller with a reference voltage to generate a PWM signal. The PWM signal is then sent to the H-bridge circuit to control the motor rotation. The pulse width of the PWM signal determines the speed of the motor.

The SLA7076MPRT uses current feedback circuit to accurately keep the current in the motor within a given value range. This allows for greater control and accuracy when controlling the motor, especially when the motor is operating in high torque, high speed, or high current conditions. Additionally, the SLA7076MPRT comes with built-in protection functions which help improve system reliability.
