STMicroelectronics is aiming at all-n-channel three-phase bridges with a 600V six-channel gate driver IC. Called STDRIVE601, it is intended to operate with mosfets or IGBTs and is protected against negative voltage spikes down to -100V, and responds to logic inputs in 85ns. It has what the firm describes as smart-shutdown circuitry, turning off “the gate-driver outputs immediately ...
