The MP5090GQHT-Z is a high-frequency power distribution switch, load driver and motor controller manufactured by Monolithic Power Systems (MPS). It is designed to provide efficient power distribution and control of motors, lighting and other devices in industrial and commercial applications. The MP5090GQHT-Z is capable of controlling up to three independent channels, each channel rated up to 50 watts.

Features and Benefits

The MP5090GQHT-Z provides several features and benefits to industrial and commercial applications. It offers an adjustable on/off threshold voltage obtained by setting a DAC parameter and a shutdown capability. The output voltage can also be trimmed from 5 to 24V. Additionally, the device is over-current protected and features soft-start and thermal shutdown. Its high-frequency control operation allows for faster switching times and stable operation at high frequencies. The MP5090GQHT-Z is also RoHS and WEEE compliant and features a small QFN-24 package.

Application Fields

The MP5090GQHT-Z is suitable for a wide range of applications including lighting and motor control. The device is suitable for automotive applications as it is designed to meet AEC-Q100 grade 1 specifications. It can be used in medical systems to control medical equipment requiring direct low-voltage current control. Additionally, it can be used in industrial equipment, such as CT/MRI scanners, where a high switching speed is required. The device can also be used in consumer applications, such as remote control toys and robotic systems.

Working Principle

The MP5090GQHT-Z is powered by a single 5V supply and functions as a high-frequency power distribution switch, load driver, and motor controller. The power gain is adjustable by setting the external DAC value and the device features built-in over-current protection and thermal shutdown. The device consists of three independent channels that can control up to 50 watts each. It has a very fast response time allowing for rapid switching and stable operation. Each channel has a fast-acting ON/OFF switching control signal, allowing for rapid and fine-grained control of the device. The device utilizes the monolithic PWM control technology for improved power efficiency and provides a switching frequency range of up to 1 MHz.
