IL24E31W012D is an integrated power module (IPM) for an inverter bridge circuit, which is applicable to 3-phase AC motors such as fish finder motors, air conditioning motors, refrigerator motors, and so on. The wide voltage range of the IPM module covers 4.5V to 58V requirements, from a single phase supply up to a 3-phase motor up to two motor phases. This advanced module is designed with a wafer-level integrated power stage IC, featuring integrated gate-driver and a wide frequency range between 0.1kHz to 10kHz, making it suitable for various applications.

In addition to the standard inverter bridge circuit, the IL24E31W012D also supports other functions, such as frequency modulation, dedicated fault protection reactions, thermal shutdown, etc. Furthermore, the wide frequency ranges of the IL24E31W012D IPM enables easy and faster design of motor applications.

Application Field

The IL24E31W012D IPM module has been designed for a variety of applications, such as: air-conditioners, fan speed regulation, pumps, compressors, and motor speed control. It is especially beneficial to applications that require a fast frequency response, since it can switch frequencies up to 10kHz, which is the highest achievable data rate in IPMs.

Moreover, the module is suitable for operating various types of motors, such as induction, BLDC, stepper, and ultrasound motors. The operating voltages range from 4.5V to 58V, ensuring that it can handle motors and power supplies of all kinds, without sacrificing performance.

The module also contains additional protection and fault management features which provide extra protection against over-currents, under-voltage, over-voltage, over-temperature or any other abnormal situations. It is capable of ensuring protection to the system by shutting down and notifying the system manager when a fault is detected.

Working Principle

The IL24E31W012D IPM module utilizes a wafer-level integrated power stage IC that is controlled by logic inputs and circuit protection features. It has an in-built high-side driver for the six power stage FET switch, four split anode/cathode output pins, and an integrated gate driver and fault protection triggering. This integration allows for an improved system design as all the components are on a single integrated circuit.

The module also features a low-side gate driver, that powers the FET switches on the negative side of the motor. The low-side driver is designed to operate at high frequencies to ensure reliable power flow. The onboard power MOSFETs are responsible for conducting the energy flow to the motor coils. When the MOSFETs are activated, they produce a magnetic field which interacts with the rotor of the motor, producing the repelling and attracting forces required to rotate.

To control the motor, the IL24E31W012D IPM module uses a set of signals to trigger the high and low sides MOSFETs in a repetitive fashion. This switching can be either direct current or alternating current depending on the type of motor control desired. Depending on the desired frequency, this signal will repeat itself multiplied by the number of MOSFETs. This is how power is transferred to the motor to produce motion.

Conclusion

The IL24E31W012D integrated power module is an advanced IPM device that is ideal for a variety of applications. It offers a wide voltage range, capable of powering up to two motor phases, and a wide frequency range of up to 10kHz, making it suitable for multiple types of motors. Furthermore, it features easy to use protection features and fault tolerance that provide extra security to the system.
