The first product, STGI15C60S, is a 20A-class device with 2 control ICs, a bootstrap diode and protection circuitry, and UVLO, smart shutdown, a temperature sensor, and a comparator.
STMicroelectronics (ST) has launched a compact intelligent power module (IPM) for motor drives. On the 13th, ST unveiled a new SLLIMM (Small Low-Loss Intelligent Molded Module) compact series.
The series supports up to 20 kHz, and the new product has a 18.8×32.8 mm footprint. It also uses a package based on DBC technology to reduce package size and integrates a 600V three-phase IGBT inverter bridge.
It also incorporates key drive and protection functions for motor control. As a result, the series is designed for use in air conditioners, heat pumps, home appliances, and industrial motor drives.
The first product is the 20A-class STGI15C60S. STGI15C60S is aimed at low- and mid-power motor drive designs and is used to miniaturize power conversion and motor control circuits in air conditioners, heat pumps, home appliances, and industrial drives.
STGI15C60S is part of the STPOWER portfolio and uses a top-side cooling package to improve thermal efficiency. It is designed for hard-switching circuit topologies operating at up to 20 kHz. The product was designed to secure stable drive and reliability.
The product integrates 2 control ICs, one for high-side IGBT drive and the other for low-side IGBT drive. It also integrates a bootstrap diode and protection circuitry to reduce the number of external components and simplify power module design.
The internal IGBTs use trench gate and short-circuit withstand technologies, and freewheeling diodes are also built in. The freewheeling diodes have fast soft recovery characteristics. This configuration is intended to achieve low saturation voltage and stable dynamic performance, with a focus on reducing power loss and improving energy efficiency.
On the signal side of the dual in-line package, a high-side reference output is placed, simplifying the bootstrap circuit layout. In addition, the driver design is optimized to reduce electromagnetic interference (EMI), and the IGBTs are also optimized to reduce electromagnetic interference (EMI).
The product is configured to integrate protection functions to improve safety and system reliability. The package insulation rating is 2,000 Vrms/min, and it includes under-voltage lockout (UVLO) to prevent issues that can occur when the drive voltage is insufficient. It also includes a smart shutdown function that cuts off operation when abnormal conditions or faults are detected.
The product also includes a temperature sensor and a comparator. The comparator serves to indicate fault conditions, and designers can identify system abnormalities based on voltage signals.
ST is pursuing a direction of improving the integration of power semiconductors for motor control systems in the SLLIMM compact series and reducing package area. Accordingly, it supports miniaturization, energy efficiency, and protection functions by being applied to air conditioners, heat pumps, and other products where the power conversion circuit faces significant space constraints.
