Isolated, Precision Half-Bridge Driver, 0.1 A Output Data Sheet ADuM1233 FEATURES GENERAL DESCRIPTION Isolated high-side and low-side outputs
The ADuM12331 is an isolated, half-bridge gate driver that
High side or low side relative to input: ±700 VPEAK
uses the Analog Devices, Inc., iCoupler® technology to provide
High-side/low-side differential: 700 VPEAK
independent and isolated high-side and low-side outputs.
0.1 A peak output current
Combining high speed CMOS and monolithic transformer
High frequency operation: 5 MHz maximum
technology, this isolation component provides outstanding
High common-mode transient immunity: >75 kV/µs
performance characteristics superior to optocoupler-based
High temperature operation: 105°C
solutions.
Wide body, 16-lead SOIC
By avoiding the use of LEDs and photodiodes, this iCoupler gate

between the high side and low side can be as high as 700 VPEAK.
Switching power supplies
As a result, the ADuM1233 provides reliable control over the switching characteristics of IGBT/MOSFET configurations over a wide range of positive or negative switching voltages.
