  ADuM1234It is an isolated half-bridge gatedrive, using Analog DevicesiCoupler® technology that provides independent and isolated high-side and low-side outputs. This isolation device combines high-speed CMOS with monolithic transformer technology to provide superior performance characteristics over optocoupler solutions.

  This oneiCoupler gate driver devices do not require LEDs and photodiodes, providing precision timing characteristics not available with optocouplers. In addition, it does not have the reliability and performance stability issues associated with optocoupler LEDs.

  Compared to gate drivers using high voltage level shifting, the ADuM1234 offers true galvanic isolation between input and output. Each output can operate at voltages up to ±700 V relative to the inputs_PEAK , thus allowing low-side switching to negative voltage. Differential voltages between the high and low sides can be up to 700 V_PEAK。

  As a result, the ADuM1234 can reliably control the switching characteristics of IGBT/MOSFET configurations over a wide range of positive or negative switching voltages.
