SIM6822M Overview

The SIM6822M is a high-performance inverter power module (IPM) from the SIM6800M Series, engineered for precise and efficient control of 3-phase motor inverter systems and variable-speed drives. It supports up to 5 A continuous output current and withstands voltages of up to 600 V (IGBT breakdown voltage), making it suitable for demanding residential and commercial motor control applications.

This module integrates all power and driver components, including six IGBTs, six freewheeling diodes, two pre-driver ICs, and three bootstrap diodes. The internal design features high-side and low-side drivers with under-voltage lockout, over-current protection, over-current limiting, and thermal shutdown for safe, reliable operation. Its high integration reduces the number of external components required, saving PCB space and improving system reliability.

SIM6822M Block Diagram

The SIM6822M functional block diagram illustrates the internal structure and signal flow of the integrated power module. At the top, the high-side level shift driver controls the upper IGBTs for each motor phase (U, V, W), receiving signals from the high-side input logic. This section also includes multiple under-voltage lockout (UVLO) circuits to protect against insufficient supply voltage, ensuring stable operation.

The lower portion features the low-side driver, which operates the lower IGBTs, coordinated by the low-side input logic. This part incorporates over-current protection (OCP), over-current limiting (OCL), and thermal shutdown functions to safeguard the device and connected load. Feedback signals such as fault output (FO) allow system-level monitoring.

Together, the high-side and low-side stages form a complete three-phase inverter bridge, enabling efficient motor control with integrated protection features, reducing the need for many external components.
