ADUM3221

Isolated 4 A Dual-Channel Gate Driver
Manufactured by:

Product Details

The ADuM3220/ADuM3221 are 4 A isolated, dual-channel gate drivers based on the Analog Devices, Inc., iCoupler® technology. Combining high speed CMOS and monolithic transformer technology, these isolation components provide outstanding performance characteristics superior to the alternatives, such as the combination of pulse transformers and gate drivers.

The ADuM3220/ADuM3221 isolators provide two independent isolation channels. They have a maximum propagation delay of 60 ns and 5 ns channel-to-channel matching. In comparison to gate drivers employing high voltage level translation methodologies, the ADuM3220/ADuM3221 offer the benefit of true, galvanic isolation between the input and each output, enabling voltage translation across the isolation barrier. The ADuM3220 has shoot-through protection logic, but the ADuM3221 does not have. They both offer a default output low characteristic as required for gate drive applications. The ADuM3220/ADuM3221 operate with an input supply voltage ranging from 3.0 V to 5.5 V, providing compatibility with lower voltage systems. The outputs of the ADuM3220A/ADuM3221A can be operated at supply voltages from 5 V to 18 V. The outputs of the ADuM3220B/ ADuM3221B can be operated at supply voltages from 8 V to 18 V.

The ADuM3220/ADuM3221 specify the junction temperature from −40°C to +125°C.

Applications
