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 up to 5 MHz bandwidth, over 75 kV/μs common-mode transient immunity, and operation up to 105°C.
The ADuM1233 isolated half‑bridge driver provides independent high‑side and low‑side outputs with up to ±700 V differential voltage and 0.1 A peak output current. It uses Analog Devices' Coupler™ technology for high‑speed CMOS operation and superior isolation compared to optocoupler solutions.
The device is supplied in a 16‑lead SOIC package, rated for UL1577 2500 V rms isolation, operating temperatures from –40 °C to +105 °C, and supports switching frequencies up to 10 Mbps. Detailed electrical characteristics, pin functions, and typical performance graphs are provided for design integration.
