ST’s high-voltage drivers are designed to optimize vector motor drive systems and feature excellent performance at high switching frequency and smart shutdown to protect the final application.

STDRIVE MOSFET and IGBT gate drivers integrate a comparator for protection, an operational amplifier for current sensing and an integrated bootstrap diode, thus reducing the number of external components required at system level.

Rugged, efficient gate drivers offer more power in small packages

ST’s new STDRIVE family of half-bridge MOSFET and IGBT gate drivers are designed to operate in harsh industrial environments withstanding high voltages up to 600 V, while maintaining good noise immunity and low switching losses. L6491, L6494, and L6498 high-voltage half-bridge gate drivers are particularly suited for medium- and high-capacity power switches thanks to their sink/source current capability up to 4 A.

The evaluation boards EVAL6494LEVAL6498L allow evaluating L6494 and L6498 high voltage, high and low-side 2 A gate drivers, designed to operate in harsh industrial environments withstanding high voltages up to 600 V, while maintaining good noise immunity and low switching losses.
