4A Dual-Channel Gate Driver
The new ADuM3220 is a 4 A isolated, dual-channel gate driver combining high speed CMOS and monolithic transformer technology. This isolation component provides outstanding performance characteristics superior to the alternatives, such as the combination of pulse transformers and gate drivers. In comparison to gate drivers employing high voltage level translation methodologies, the ADuM3220 offers the benefit of true, galvanic isolation between the input and each output, enabling voltage translation across the isolation barrier.
AEC-Q100 Qualified Hot-Swappable I2C Digital Isolator
The ADuM1250W is the industry's first automotive grade product to provide true bidirectional isolation for the I2C serial bus. The ADuM1250W reduces board space by as much as 80% and greatly reduces the system cost as well by eliminating optocouplers and support circuitry previously required in isolated I2C interfaces.
