Isolated Precision Half-Bridge Driver, 4.0 A Output Data Sheet ADuM7223 FEATURES GENERAL DESCRIPTION 4.0 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 matching 3.0 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
DD1 A Version UVLO, V
only 12 ns at 12 V.
DDA and VDDB (VDD2) at 4.1 V B 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 a wide range of positive or negative switching voltages.
