The ADuM3220/ADuM32211 are isolated, 4A dual-channel gate drivers based on the Analog Devices, Inc., iCoupler®technology. Combining high speed CMOS and monolithic transformer technology, these isolation components provide outstandingperformance characteristics superior to the alternatives, such as the combination of pulse transformers and gate drivers.
The ADuM3220/ADuM3221 provide digital isolation in two independent isolation channels. They have a maximum propagationdelay of 60 ns and 5 ns channel-to-channel matching. In comparison to gate drivers that employ high voltage level translationmethodologies, 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, which preventsboth outputs from being on at the same time, whereas the ADuM3221 allows both outputs to be on at the same time. Both partsoffer 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 lowervoltage systems. The outputs of the ADuM3220A/ADuM3221A can be operated at supply voltages from 4.5 V to 18 V. The outputs ofthe ADuM3220B/ADuM3221B can be operated at supply voltages from 7.6 V to 18 V.
The junction temperature of the ADuM3220/ADuM3221 is specified from −40°C to +125°C.
Applications
- Isolated synchronous dc-to-dc converters
- MOSFET/IGBT gate drivers
