Isolated, 4 A Dual-Channel Gate Driver Data Sheet ADuM3220/ADuM3221 FEATURES GENERAL DESCRIPTION 4 A peak output current The ADuM3220/ADuM32211 are isolated, 4 A dual-channel gate Precise timing characteristics drivers based on the Analog Devices, Inc., iCoupler® technology. 60 ns maximum isolator and driver propagation delay Combining high speed CMOS and monolithic transformer technol- 5 ns maximum channel-to-channel matching ogy, these isolation components provide outstanding performance High junction temperature operation: 125°C characteristics superior to the alternatives, such as the combination 3.3 V to 5 V input logic of pulse transformers and gate drivers. 4.5 V to 18 V output drive The ADuM3220/ADuM3221 provide digital isolation in two UVLO at 2.5 V V DD1 independent isolation channels. They have a maximum propagation ADuM3220A/ADuM3221A UVLO at 4.1 V V DD2 delay of 60 ns and 5 ns channel-to-channel matching. In comparison ADuM3220B/ADuM3221B UVLO at 7.0 V V DD2 to gate drivers that employ high voltage level translation method- Thermal shutdown protection at >150°C ologies, the ADuM3220/ADuM3221 offer the benefit of true, Output shoot-through logic protection on the ADuM3220 galvanic isolation between the input and each output, enabling Default low output voltage translation across the isolation barrier. The ADuM3220 High frequency operation: dc to 1 MHz has shoot-through protection logic, which prevents both outputs CMOS input logic levels from being on at the same time, whereas the ADuM3221 allows High common-mode transient immunity: >25 kV/μs both outputs to be on at the same time. Both parts offer a default Enhanced system-level ESD performance per IEC 61000-4-x output low characteristic as required for gate drive applications. Safety and regulatory approvals UL recognition The ADuM3220/ADuM3221 operate with an input supply voltage 2500 V rms for 1 minute per UL 1577 ranging from 3.0 V to 5.5 V, providing compatibility with lower CSA Component Acceptance Notice #5A voltage systems. The outputs of the ADuM3220A/ADuM3221A VDE certificate of conformity can be operated at supply voltages from 4.5 V to 18 V. The outputs DIN V VDE V 0884-10 (VDE V 0884-10):2006-12 of the ADuM3220B/ADuM3221B can be operated at supply V = 560 V peak voltages from 7.6 V to 18 V.
