      The SDH2138 is high voltage high speed power MOSFET and IGBT three-phase gate driver, including three independent half bridge drivers. Built-in dead time avoids the simultaneous conduction of both high side and low side MOSFETs, and built-in input filtering is used for avoiding noise interference. External enable control is available for turning off six channel outputs simultaneously. Meanwhile, it features undervoltage protection and overcurrent protection for turning off six channel output if any abnormality.
