Solution Description
The STDRIVE601 is a high voltage device manufactured with BCD6s offline technology. It is a single-chip with three half-bridge gate drivers for N-channel power MOSFETs or IGBTs suitable for 3-phase applications.
This device embeds everything what is needed to build a complete power stage, including:
- Three half-bridge gate drivers
- Smart protections
- Signal conditioning
All the STDRIVE601 outputs can sink and source 350 mA and 200 mA respectively. Prevention from cross conduction is ensured by interlocking and deadtime function.
Key target applications:
- Home and Industrial refrigerators compressors
- Industrial drives, pumps, fans
- Air conditioning compressors & fans
- Corded power tools, garden tools
- Home appliances
The device has dedicated input pins for each output and a shutdown pin. The logic inputs are CMOS/TTL compatible down to 3.3 V for easy interfacing with control devices. Matched delays between low-side and high-side sections guarantee no cycle distortion and allow high frequency operation.
ST offer includes a full ecosystem with software libraries, tools, GUI as well as high voltage power MOSFETs or IGBTs.
