High Voltage, Isolated Gate Driver with Internal Miller Clamp, 2.3 A Output Enhanced Product ADuM4121-1-EP FEATURES GENERAL DESCRIPTION 1 2.3 A peak output current (typical) The ADuM4121-1-EP is a 2.3 A isolated, single-channel driver 2.5 V to 6.5 V input that employ Analog Devices, Inc., iCoupler technology to provide 7.5 V to 35 V output precision isolation. The ADuM4121-1-EP provides 5 kV rms Undervoltage lockout (UVLO) at 2.5 V V and 7.5 V V DD1 DD2 isolation in the wide-body, 8-lead SOIC package. Combining high Precise timing characteristics speed CMOS and monolithic transformer technology, this 53 ns maximum isolator and driver propagation delay isolation component provides outstanding performance CMOS input logic levels characteristics superior to alternatives such as the combination High common-mode transient immunity: >150 kV/s of pulse transformers and gate drivers. High junction temperature operation: 125C The ADuM4121-1-EP operates with an input supply ranging Default low output from 2.5 V to 6.5 V, providing compatibility with lower voltage Internal Miller clamp systems. In comparison to gate drivers that employ high voltage Safety and regulatory approvals (pending) level translation methodologies, the ADuM4121-1-EP offers the UL recognition per UL 1577 benefit of true, galvanic isolation between the input and the output. 5 kV rms for 1-minute withstand The ADuM4121-1-EP includes an internal Miller clamp that CSA Component Acceptance Notice 5A activates at 2 V on the falling edge of the gate drive output, VDE certificate of conformity (pending) supplying the driven gate with a lower impedance path to reduce DIN V VDE V 0884-10 (VDE V 0884-10): 2006-12 the chance of Miller capacitance induced turn on. V = 849 V peak IORM Wide-body, 8-lead SOIC The ADuM4121-1-EP provides reliable control over the switching characteristics of insulated gate bipolar transistor (IGBT)/metal ENHANCED PRODUCT FEATURES oxide semiconductor field effect transistor (MOSFET) configura- Supports defense and aerospace applications (AQEC standard) tions over a wide range of switching voltages. Military temperature range (55C to +125C) Additional application and technical information can be found Controlled manufacturing baseline in the ADuM4121-1 data sheet. 1 assembly/test site 1 fabrication site Product change notification Qualification data available on request APPLICATIONS Missiles and munitions Avionics Unmanned systems Isolated IGBT/MOSFET gate drives FUNCTIONAL BLOCK DIAGRAM UVLO TSD ADuM4121-1-EP V 1 8 V DD1 DD2 DECODE AND 2 ENCODE 7 V + V OUT I LOGIC V 3 6 CLAMP I 2V 4 5 GND GND 1 UVLO 2 Figure 1. 1 Protected by U.S. Patents 5,952,849 6,873,065 and 7,075,329.
