The MP6509GF-Z is a high-performance, energy-efficient pulse-width modulation (PWM) controller/driver, designed to control direct current (DC) brushless or stepper motors. It offers several advantages such as over-temperature protection, short-circuit protection, and adjustable dead-time control. This converter is suitable for both industrial and consumer applications that demand superior performance and reliability.

The design of the MP6509GF-Z includes two sets of half-bridge drivers for the three phases of the controlled motor. The output transistors have a low-going switch voltage combined with a maximum peak switch current supply of 9 A and an adjustable dead-time control that allows users to tailor the converter’s dead-time to their specific application. In addition, the pulse-width modulation (PWM) controller offers protection features such as over-temperature shutdown and a high-side switch current limit.

The MP6509GF-Z works in conjunction with other products that are compatible with power management integrated circuits (PMICs) to create a complete power supply solution. The required external components to control a motor in this manner include an inductor, several capacitors, voltage references and a pull-up or pull-down resistor. The half-bridge outputs can be controlled by either a low-speed or high-speed PWM input.

The nominal operating voltage of the MP6509GF-Z is between 6 V and 20 V, making the converter suitable for a wide range of applications. The IC is equipped with an adjustable dead-time control and an over-temperature protection circuit that prevents damage to components that may occur if the temperature exceeds a certain level.

The MP6509GF-Z is designed to control both brushed and brushless motors. Brushless motors require three-phase control, but the MP6509GF-Z can be used for two-phase control of brushed motors, allowing for more flexibility in motor control applications. The controller has a low-going switch voltage that reduces electromagnetic interference and increases motor lifetime.

The MP6509GF-Z features adjustable dead-time control and an adjustable over-temperature protection circuit for more safety. Additionally, the PWM controller includes a high-side switch current limit, which provides protection against overloads and shorts. It also has a very low stand-by current, making it suitable for battery-powered applications.

In conclusion, the MP6509GF-Z offers performance and reliability that is especially suited to industrial or consumer applications. It is a high-performance, energy-efficient pulse-width modulation (PWM) controller/driver that is capable of controlling direct current (DC) brushless or stepper motors. It includes two sets of half-bridge drivers for the three phases of the controlled motor, adjustable dead-time control, over-temperature protection and high-side switch current limit, making it an ideal choice for safety-sensitive applications.
