ADUM1233

Isolated, Precision Half-Bridge Driver, 0.1 A Output ADuM1233 FEATURES Isolated high-side and low-side outputs High side or low side relative to input: ±700 VPEAK High side/low side differential: 700 VPEAK 0.1 A peak output current High frequency operation: 5 MHz maximum High common-mode transient immunity: >75 kV/μs High temperature operation: 105°C Wide body, 16-lead SOIC UL1577 2500 V rms input-to-output withstand voltage GENERAL DESCRIPTION The ADuM12331 is an isolated, half-bridge gate driver that employs 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 drivers employing 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 ±700 VPEAK relative to the input, thereby supporting low-side switching to negative voltages. The differential voltage between the high side and low side can be as high as 700 VPEAK. As a result, the ADu...
