STMicroelectronics Adds Two 600V Three-Phase Gate Drivers: Priced From 1.49 Dollars per 1,000 Pieces and Now in Production
STMicroelectronics extended its STDRIVE family of three-phase gate drivers on November 12, 2026, in a company release issued from Geneva, Switzerland, with two new 600V devices, the STDRIVE631P and the STDRIVE631N, that let motor drives and inverters operate directly from a high-voltage bus. The two devices integrate three half-bridge drivers for N-channel power MOSFETs or IGBTs in a compact SO-28 package, for applications such as fans, pumps and compressors for white goods.
The company said both devices use its BCD6-OFFLINE technology, with outputs capable of sourcing 1.0A and sinking 0.85A and robustness to below-ground spikes of up to 100V. Each output integrates a zero-drop bootstrap diode, and propagation delays are matched for all channels. The STDRIVE631P uses positive, active-high input logic, while the STDRIVE631N uses negative, active-low logic. Protection includes an integrated comparator with smart shutdown for faults such as overcurrent and overtemperature, interlocking and deadtime control to prevent cross conduction, and under-voltage lock-out for the low-side and high-side driving sections.
The company said the devices provide plus or minus 50V per nanosecond of dV/dt transient immunity and protection against electrostatic discharge events of up to 2kV under the human body model. Evaluation boards EVLSTDRIVE631P and EVLSTDRIVE631N are also available, each containing a complete three-phase inverter built with STGD6M65DF2 IGBTs, with selectable single- or three-shunt current sensing and a 34-pin motor-control connector for STM32 microcontrollers. Both devices are in production now, rated for minus 40 degrees Celsius to 125 degrees Celsius, with pricing starting from 1.49 dollars for orders of 1,000 pieces.
