Key synergy to improve performance

Motor drive control is the system cooperation of each control unit. In addition to the core main control chip, precise control, automation, and intelligent drive management must be realized. The drive IC and power devices play key synergistic functions, and can even help the solution system greatly improve Efficiency: Power integration technology needs to achieve high and low voltage compatibility, high performance, high efficiency and high reliability on a limited chip area. High-power integrated circuits use more hybrid integrated circuits, and medium and low-power integrated circuits use monolithic integration. The technology is complex and the reliability requirements are high; Fuhong Chuangxin's chip research and development team has been deeply involved in the fields of analog, digital and power semiconductor chips for many years. The research and development products are widely used in related fields. They are familiar with the integration of multiple chip technologies. In Fuhong Chuangxin Motor In the product ecology of drive control chips, drive ICs, MOSFETs, and IPMs occupy an important position, which play a key role in the reliability, intelligent control, system cost, performance and service life of the motor system:

Driver IC that saves energy and reduces emissions and helps improve system efficiency

HVIC (High Voltage Power Integrated Circuit) is the integration of multiple high voltage devices, low voltage analog devices and logic circuits on a single chip.

The company’s dedicated motor drive chip HVIC, gate/gate drive Stronger ability helps reduce system switching losses, reduce system heat generation, and improve system efficiency; it is extraordinary in a variety of different applications such as motor drives, DC-DC converters, DC-AC inverters, and class-D power amplifiers. which performed;

In 2020, Fuhong Chuangxin launched the first high-voltage 5A high-current driver IC in China: FD2109S, a 180V half-bridge gate driver chip, suitable for high-voltage, high-speed driving of N-type power devices, especially, built-in undervoltage, input filter , Through prevention, dead zone protection, to prevent the power tube from working under too low voltage during system operation, and to prevent damage to the half-bridge power device.

Power device realizes optimal motor drive control scheme

The contradiction between the power semiconductor power tolerance and the switching frequency is that the higher the power and the higher the withstand voltage, the lower the allowable switching frequency. The MOSFET will withstand the maximum voltage shock at the moment of turning off, and the switching frequency cannot be changed. In the case of, you can only rely on the switch performance to obtain the overall performance of the system;

Fuhong Chuangxin adopts the international leading multi-layer epitaxy + special process technology, good high-temperature leakage characteristics, and ultra-fast reverse recovery characteristics; its excellent switching performance helps to reduce the overall heating of the system and achieve high efficiency and low loss. While saving circuit board space, it can optimize the overall cost of the motor drive control scheme, with short reverse recovery time (Trr), small on-resistance, high voltage resistance, space saving, low operating temperature rise, and low switching loss, which is for consumption Provide stable, reliable and consistent high-voltage solutions in the fields of electronics and industry;

For example: FMD7N60P5 is fabricated using planar self-aligned technology, silicon-based N-channel enhancement type vertical double diffused metal oxide semiconductor field effect transistor, which reduces conduction loss, improves switching characteristics and increases avalanche energy; this transistor is available Used in various power switching circuits to achieve system miniaturization and improve efficiency.

Intelligent, precise and high-performance IPM

In addition to integrating power devices and drive circuits, IPM also integrates protection circuits such as undervoltage, input filtering, and pass-through prevention. IPM is small in size, high in reliability, and has won an increasingly large market. It is mainly used for motor control and motor drive. Ideal choice of power electronic devices in the field;
