Power management integrated circuits (PMICs) are integrated circuit chips specialized for the power management and control of various electrical systems and processes. They are used in portable and stationary electronics applications, across a wide variety of industries. The SLA7073MPRT is one such PMIC and is specifically designed to drive and control motors used in industrial, robotics and consumer applications.

The SLA7073MPRT is a 3-phase full-bridge motor driver, which features integrated temperature sensing and protection, and a low operating noise level. This device employs a paralleled upper and lower MOSFET structure, thus enabling it to perform efficiently and operate at higher speeds in order to meet the demands of certain motor control applications. It is capable of providing up to 3.2 A per phase of continuous current, and operates from a wide range of voltages up to 40 Vdc. The SLA7073MPRT also includes an anti-clockwise/clockwise direction control, as well as an overcurrent and thermal shutdown feature for operation safety.

The SLA7073MPRT’s application field includes DC and stepping motors, such as those used in robots, automated equipment and household appliances. This device enables the precise and efficient control of these motors, and its low noise output is suitable for use in audio and sound equipment. In addition the SLA7073MPRT is also capable of PWM control to enable the automated assembly and packing of materials, and is suitable for controlling fans, pumps and other equipment found in a variety of industries, where an accurate and reliable motor drive is required.

The working principle of SLA7073MPRT is relatively straightforward. At its core is an H-bridge which consists of four transistors and four diodes: two regular transistors and two transistors which are equipped with the appropriate control circuitry to act as a switch. This circuit switches two different polarities of the power rail, thus enabling the motor to be driven in either direction. This offers the advantage over single rail power sources, where it is not possible to reverse the motor’s direction without additional circuits or components. The motor can be controlled by varying the duty cycle (or pulse width modulation) of the on and off transistors, thus changing the speed of the motor.

The SLA7073MPRT also includes several essential protection features. An overcurrent protection feature monitors the current in each of the phases and trips the device to protect against overheating or short-circuits. Additionally, thermal protective circuitry is incorporated in order to protect against excessive temperature in the device. This combination of features ensures the safe operation of the device and its longevity in a wide range of industrial and commercial applications.

The SLA7073MPRT is an ideal solution for driving and controlling DC/Stepping motors in a wide range of industrial, robotics, and consumer applications. Its integrated protection features, low operating noise, and varied operating voltages make it an ideal choice for applications which require reliable and accurate motor drive and control.
