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 can 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.

The STDRIVE® GaN gate drivers devices are half-bridge gate drivers for Enhancement mode GaN FETs or N-channel power MOSFET.
The high-side section is designed to stand a voltage up to 600 V and is suitable for designs with bus voltage up to 500 V. The device is designed for driving high-speed GaN and Si FETs thanks to high current capability, short propagation delay and operation with supply voltage down to 5 V.
They feature UVLO protection on both the lower and upper driving sections, preventing the power switches from operating in low efficiency or dangerous conditions, and the interlocking function avoids cross-conduction conditions. The logic inputs are CMOS/TTL compatible down to 3.3 V for easy interfacing with microcontroller and DSP.

ST offers the STGAP series of isolated gate drivers for MOSFETs and IGBTs that provide galvanic isolation between the input section, which connects to the control part of the system, and the MOSFET or IGBT being driven.
Galvanic isolation is attained using a high-voltage, on-chip, micro transformer that ensures commands and diagnostic information are reliably transferred to and from the floating – with respect to ground – section of the circuit.
STGAP isolated gate drivers are extremely flexible as they provide a large number of parameters that can be adjusted to best match the selected MOSFET or IGBT and system requirements. They also provide extensive diagnostic features to help enhance system robustness and reliability. Evaluation hardware, software and technical documentation are available to help minimize time to market.
