High Voltage, Isolated Gate Driver with Internal Miller Clamp, 2 A Output Data Sheet ADuM4121/ADuM4121-1 FEATURES GENERAL DESCRIPTION 1 2 A peak output current (<2 R ) The ADuM4121/ADuM4121-1 are 2 A isolated, single-channel DSON 2.5 V to 6.5 V input drivers that employ Analog Devices, Inc.s iCoupler technology 4.5 V to 35 V output to provide precision isolation. The ADuM4121/ADuM4121-1 Undervoltage lockout (UVLO) at 2.5 V V DD1 provide 5 kV rms isolation in the wide-body, 8-lead SOIC package. Multiple UVLO options on V DD2 Combining high speed CMOS and monolithic transformer Grade A: 4.4 V (typical) UVLO on V DD2 technology, these isolation components provide outstanding Grade B: 7.3 V (typical) UVLO on V DD2 performance characteristics superior to alternatives such as the Grade C: 11.3 V (typical) UVLO on V DD2 combination of pulse transformers and gate drivers. Precise timing characteristics The ADuM4121/ADuM4121-1 operate with an input supply 53 ns maximum isolator and driver propagation delay ranging from 2.5 V to 6.5 V, providing compatibility with lower CMOS input logic levels voltage systems. In comparison to gate drivers that employ high High common-mode transient immunity: >150 kV/s voltage level translation methodologies, the ADuM4121/ High junction temperature operation: 125C ADuM4121-1 offer the benefit of true, galvanic isolation Default low output between the input and the output. Internal Miller clamp The ADuM4121/ADuM4121-1 include an internal Miller clamp Safety and regulatory approvals (pending) that activates at 2 V on the falling edge of the gate drive output, UL recognition per UL 1577 supplying the driven gate with a lower impedance path to reduce 5 kV rms for 1-minute withstand the chance of Miller capacitance induced turn on. CSA Component Acceptance Notice 5A VDE certificate of conformity (pending) Options exists to allow the thermal shutdown to be enabled or DIN V VDE V 0884-10 (VDE V 0884-10): 2006-12 disabled. As a result, the ADuM4121/ADuM4121-1 provide V = 849 V peak IORM reliable control over the switching characteristics of insulated Wide-body, 8-lead SOIC gate bipolar transistor (IGBT)/metal oxide semiconductor field, effect transistor (MOSFET) configurations over a wide range of APPLICATIONS switching voltages.
