ADUM1233BRWZ Datasheet PDF - ADI

●The ADUM1233BRWZ is an isolated half-bridge Gate Driver that uses the Analog Devices Inc., iCoupler® technology to provide independent and isolated high-side and low-side outputs. Combining high speed CMOS and monolithic transformer technology, this isolation component provides outstanding performance characteristics superior to optocoupler-based solutions. By avoiding the use of LEDs and photodiodes, this iCoupler gate drive device is able to provide precision timing characteristics not possible with optocouplers. Furthermore, the reliability and performance stability problems associated with optocoupler LEDs are avoided. In comparison to gate driver that uses high voltage level translation methodologies, the ADuM1233 offers the benefit of true, galvanic isolation between the input and each output. Each output can be operated up to ±700VPEAK relative to the input, thereby supporting low-side switching to negative voltages.

● Isolated high-side and low-side outputs

● High frequency operation - 5MHz maximum

● >75kV/µs High common-mode transient immunity
