The FD3H0485G is a three-phase digital drive integrated circuit developed by Fairchild Semiconductor. The integrated circuit is designed to provide a robust microcontroller-based control logic for three-phase brushless DC (BLDC) motor applications. The integral microcontroller is programmed to provide high-performance motor control, monitoring, and protection for the user\'s application. This article provides an overview of the FD3H0485G motor control integrated circuit, as well as an introduction to the application field and working principle of this device.

The FD3H0485G integrated circuit is based on an 8-bit, highly integrated flash microcontroller from Freescale, making it ideal for motor control applications. The device offers a range of features to help improve motor performance, such as advanced anti-crossover protection, over-current protection, 3-wire serial or 4-wire serial bus control, temperature sensing, and programmable current control. The device operates with 3.3V or 5V logic level, has a complete 8-bit microcontroller core with up to 16 Kbytes of on-chip Flash/EEPROM memory and 5 Kbytes of SRAM for program execution. It also has onboard PWM generator, comparator, input watcher and clock generator.

The FD3H0485G\'s application fields include consumer and industrial products such as exhaust fans, washing machines, refrigeration and air conditioning (HVAC) controls, dishwashers, compressors, power tools, and other motor-driven applications. The integrated circuit features a pre-programmed motor control system that allows users to easily configure the IC for their specific use. The IC also provides advanced algorithm tuning capabilities for optimized motor performance. The device is designed to be used in a low-cost environment with minimal external components, allowing for an easy integration and enhanced motor performance. It is also RoHS compliant, making it an ideal choice for eco-friendly designs.

The FD3H0485G\'s working principle is based on Freescale\'s S08 MCU architecture. The principle is to generate a PWM signal to control the motor\'s speed. The PWM consists of two pulse trains with complementary output signals that are inverted each period. The period of the PWM is determined by a prescaler, and the PWM based logic is used to control the motor to a specific speed. The device also features a boot loader and application boot modes to allow the user to program their own algorithms. The user can adjust the duty cycle of the PWM to control the motor\'s speed. The internal control logic can detect over-current or over-temperature conditions and activate the current protection.

In conclusion, the FD3H0485G is an ideal choice for a wide range of motor control applications, providing high performance control, monitoring, and protection functions in a low-cost and easy to integrate package. The integrated Flash/EEPROM memory, SRAM, and versatile PWM generator combine to provide optimized motor control algorithms for improved motor performance. Additionally, the PWM based control logic, current protection, and temperature sensing give users complete control and protection over their motor operation. Therefore, the FD3H0485G is a great choice for consumer and industrial motor control applications.
