FSBB30CH60C: Efficient and Reliable Intelligent Power Module to Drive the Future of Motor Control

As the demand for efficient, compact and reliable motor drive solutions for household appliances and industrial equipment continues to grow, Intelligent Power Modules (IPMs) are an important part of the push for technological advancement. the FSBB30CH60C, a Motion SPM® 3 series product from onSEMI, stands out for its superior performance and integrated design, making it the ideal choice for low-power motor drive applications. The FSBB30CH60C is ideal for low-power motor drive applications.

All-in-one design simplifies system architecture

The FSBB30CH60C is a highly integrated three-phase inverter module that combines a 600V, 30A IGBT power device with gate drive circuitry, protection features, and bootstrap diodes in a compact package. Its features include:

- Three-phase IGBT inverter bridge: supports efficient DC to AC power conversion.

- Built-in bootstrap diode: simplifies PCB layout and reduces external components.

- Separate negative DC link terminals: Supports independent detection of each phase's current for enhanced control flexibility.

This integrated design significantly reduces design complexity and cost, enabling developers to quickly build high-performance inverter systems.

Efficient Heat Dissipation for Enhanced Reliability

The FSBB30CH60C uses an Aluminium Nitride (AlN) Direct Bonded Copper (DBC) substrate, which has extremely low thermal resistance and high thermal conductivity. Compared to traditional aluminium oxide (Al2O3) substrates, the AlN substrate is able to conduct heat more efficiently from the internal devices to the heat sink, thus ensuring stable operation of the module under high power density conditions. In addition, it has a rated power dissipation of 106W and an operating junction temperature range of -40°C to +150°C, enabling it to be used in harsh environments. This excellent thermal management performance not only extends module life, but also improves overall system reliability.

Comprehensive Protection Features for System Safety

The FSBB30CH60C has a variety of built-in protection features, including:

- Under Voltage Lockout (UVLO): Prevents unstable operation due to insufficient voltage;

- Short circuit protection (SCP): for low-side IGBTs, triggering shutdown operation when a short circuit is detected;

- Fault Signal Output: provides fault information via an open collector output, requiring an external pull-up resistor (4.7kΩ recommended).

These protection mechanisms enable real-time monitoring of the module's operating status and rapid response in abnormal situations, thus effectively protecting the system from damage and improving overall safety.

High-performance driver for diverse applications

The FSBB30CH60C supports a wide range of motor types, including:

- AC induction motors (ACIM)

- Brushless DC motors (BLDC)

- Permanent magnet synchronous motors (PMSM)

Its 600V withstand voltage and 30A continuous current capability make it ideal for low power inverter applications in household appliances (e.g. air conditioners, washing machines, refrigerators, etc.) as well as small industrial equipment. The module supports a single grounded power supply design, eliminating the need for optocoupler isolation, greatly simplifying control system design while improving signal transmission stability.

Economical and efficient, reducing overall costs

Thanks to its highly integrated design, the FSBB30CH60C significantly reduces external component requirements and PCB area, resulting in lower bill of materials (BOM) costs. In addition, its built-in high-voltage integrated circuit (HVIC) enables optocoupler isolation, significantly reducing the overall system size. This not only saves manufacturers development time and production costs, but also provides end-users with a more energy-efficient, lower operating cost solution.

Summary: Ideal for driving the future

The FSBB30CH60C offers a cost-effective and reliable solution for low-power motor drive applications thanks to its compact all-in-one design, efficient heat dissipation capabilities, comprehensive protection mechanisms and broad applicability. Whether for household appliances or industrial equipment, the module helps manufacturers achieve more efficient, safer and competitive product designs. Driven by the trend of energy saving, emission reduction and intelligence, intelligent power modules like the FSBB30CH60C will continue to lead the way in technological innovation, bringing users around the world an even better experience.
