ソリューション概要

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.
