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.
