Power up your brushless motors with STDRIVE102 advanced gate drivers

The STDRIVE102 series integrates flexible 3-phase gate drivers for controlling six external N-channel MOSFETs, with programmable gate current for precise tuning. Its integrated analog front end, featuring operational amplifiers and comparators, enables flexible current sensing and robust overcurrent protection, now available in 5 mm × 5 mm and 6 mm × 6 mm QFN packages.

STDRIVE102 integrated 3-phase drivers for BLDC motors

Advanced 3-phase low voltage gate driver family for enhanced features, robustness, and performances

Designed for versatility and efficiency, this advanced product lineup powers applications up to 50 V. It is ideal for battery-powered tools, vacuum cleaners, e-bikes, robotics, and small appliances where every milliampere counts. The embedded analog front end supports current sensing and protection functions. The STDRIVE102BP integrates three PGAs and three comparators, while the STDRIVE102P integrates one PGA and one comparator. The PGAs amplify shunt-voltage signals from each motor phase for accurate current monitoring, while the comparators enable fast and reliable overcurrent detection. SPI connectivity supports device configuration and diagnostics.
