Isolated Precision Half-BridgeDriver, 4.0 A OutputData SheetADuM7223FEATURESGENERAL DESCRIPTION4.0 A peak output current The ADuM7223 is a 4.0 A isolated, half-bridge gate driver that Working voltage employs Analog Devices, Inc., iCoupler® technology to provide High-side or low-side relative to input: 565 V peak independent and isolated high-side and low-side outputs. High-side to low-side differential: 700 V peak Combining high speed CMOS and monolithic transformer High frequency operation: 1 MHz maximum technology, these isolation components provide outstanding Precise timing characteristics performance characteristics superior to alternatives such as the 64 ns maximum propagation delay combination of pulse transformers and non-isolated gate 8.5 ns maximum channel-to-channel matching3.0 V to 5.5 V input voltage drivers. By integrating the isolator and driver in a single 4.5 V to 18 V output drive package, propagation delay is a maximum of only 64 ns, and the UVLO supply at 2.8 V V propagation skew from channel to channel is a maximum of DD1A Version UVLO, V only 12 ns at 12 V. DDA and VDDB (VDD2) at 4.1 VB Version UVLO, VDDA and VDDB at 6.9 V The ADuM7223 provides two independent isolation channels. C Version UVLO, VDDA and VDDB at 10.5 V The ADuM7223 operates with an input supply ranging from 3.0 V CMOS input logic levels to 5.5 V, providing compatibility with lower voltage systems. High common-mode transient immunity: >25 kV/μs The outputs operate in a wide range from 4.5 V to 18 V with High junction temperature operation: 125°C three output voltage versions available. The 5 mm × 5 mm, LGA Default low output 5 mm × 5 mm, 13-terminal LGA package provides 565 V operating voltage from input to output
and 700 V from output to output. APPLICATIONS In comparison to gate drivers employing high voltage level Switching power supplies translation methodologies, this gate driver offers the benefit of Isolated IGBT/MOSFET gate drives true, galvanic isolation between the input and each output. As a Industrial inverters result, this gate driver provides reliable control over the
switching characteristics of IGBT/MOSFET configurations over
