Power Management Integrated Circuit (PMIC) is a power semiconductor device that improves the efficiency and reliability of power systems in a wide range of applications. PMICs are used to regulate voltage or current outputs to safeguard a wide range of devices from power outages. In addition to providing protection from power outages, PMICs can also reduce the system size and extend the life of the device by optimizing the power device layout and providing the most appropriate operating conditions for each device.

IRMCK182M Motor Driver, Controller

One of the most popular type of PMICs is the IRMCK182M motor driver, controller. The IRMCK182M is a high-efficiency, low-cost motor driver, controller IC. It has an integrated charge pump controller which allows it to control up to 5A external NMOS devices. It can also operate in both linear and buck-boost modes, providing a wide range of potential functions and features. The IRMCK182M can be used in applications such as handheld equipment, solar battery management systems, electric vehicle and motor drives.

In addition to its integrated charge pump controller, other features of the IRMCK182M include:

• High efficiency (up to 95%), allowing it to operate at lower power levels.
• High current capacity (up to 5A @ 20V), allowing it to operate with more powerful motors.
• Integrated MOSFET drivers that provide a better overall switching performance.
• No external driver or bootstrap device required.
• On-board emergency stop feature, which allows for safe shutdown in case of emergency conditions.
• Integrated charge pump controller, which allows for faster switching speed of the motor driver.
• Integrated over-current protection, allowing it to rapidly cut off power in case of an overload.
• Integrated oscillator, which allows the motor driver to adjust its switching frequency, providing better thermal efficiency.

The IRMCK182M is primarily used in permanent-magnet synchronous motor drives, such as single and three phase inverters, AC servo drives and battery management systems. It can also be used in applications where simple speed control and current measurement is required. As the IRMCK182M has an integrated charge pump controller, it saves the cost of a separate driver or gate drive IC, as well as reducing the component count and maximizing the efficiency of the overall system.

In addition to its integrated driver, other features of the IRMCK182M include:

• Integrated over-voltage protection, preventing the motor from being overloaded.
• Automatic thermal shutdown, providing protection for the motor in case of overheating.
• Integrated PWM control, which allows for control of the motor’s speed and torque.
• Integrated reverse voltage protection, providing further protection for the motor in case of a power spike.
• An integrated digital isolation, which reduces the current losses in the motor.

The IRMCK182M is a versatile and reliable motor driver, controller IC. It offers a wide range of features and can be used in a variety of applications, making it a great choice for designers who want to improve the efficiency, reliability and cost of their designs.
