The two companies are developing and will jointly market 650V/50A and 1200V/10A industrial modules, which according to the companies, simplify design challenges and shrink the bill of materials for HVAC systems, industrial servo drives, industrial washing machines, and general-purpose inverters over 3 kW. The ST/Sanken IPM product roadmap will continue with 650V/50A automotive-grade modules for high-voltage compressors, pumps, and cooling fans.
The new IPMs integrate a complete inverter stage including six short-circuit rugged IGBTs with freewheeling diodes, associated high-side and low-side gate drivers in a single package designed optimally for thermal efficiency. Ready to operate in hard switching up to 20 kHz, the modules also contain built-in features for protection and control. These include bootstrap diodes, short-circuit protection, under-voltage lockout protection for gate drivers, a 100 kΩ thermistor for temperature monitoring, and a comparator for fault protection.
Additional benefits include:
- 3.3V/5V TTL/CMOS-compatible inputs with hysteresis
- Shutdown input and Fault output
- Separate open-emitter outputs
- Soft-recovery diodes
- Fully isolated package with isolation rating of 2500Vrms/min
Engineering samples of the industrial IPMs will be available in March 2021 and production will begin soon afterwards. Samples of the automotive-grade devices will be available in second half of 2021.
