Isolated Precision Gate Driver, 4.0 A Output Data Sheet ADuM3123 FEATURES GENERAL DESCRIPTION 1 4.0 A output short-circuit pulsed current The ADuM3123 is a 4.0 A isolated, single channel driver that Isolated working voltage employs Analog Devices, Inc., iCoupler technology to provide Secondary side to input side: 537 V precision isolation. The ADuM3123 provides 3000 V rms High frequency operation: 1 MHz maximum isolation in the narrow-body, 8-lead SOIC package. Combining 3.3 V to 5 V input logic high speed CMOS and monolithic transformer technology, 4.5 V to 18 V output drive these isolation components provide outstanding performance Undervoltage lockout (UVLO): 2.8 V V DD1 characteristics superior to alternatives such as the combination Precise timing characteristics of pulse transformers and gate drivers. 64 ns maximum isolator and driver propagation delay The ADuM3123 operates with an input supply ranging from Complementary metal oxide semiconductor (CMOS) input 3.0 V to 5.5 V, providing compatibility with lower voltage logic levels systems. In comparison to gate drivers employing high voltage High common-mode transient immunity: >25 kV/s level translation methodologies, the ADuM3123 offers the High junction temperature operation: 125C benefit of true, galvanic isolation between the input and the Default low output output. The output can continuously operate up to 380 V rms Safety and regulatory approvals (pending) relative to the input. UL recognition per UL 1577 As a result, the ADuM3123 provides reliable control over the 3000 V rms for 1 minute SOIC long package switching characteristics of IGBT/MOSFET configurations over CSA Component Acceptance Notice 5A a wide range of positive and negative switching voltages.
