Isolated Precision Half-Bridge

Driver, 4.0 A Output

Data Sheet

ADuM7223

FEATURES

GENERAL DESCRIPTION

4.0 A peak output current

Working voltage

The ADuM7223 is a 4.0 A isolated, half-bridge gate driver that

employs Analog Devices, Inc., iCoupler® technology to provide

independent and isolated high-side and low-side outputs.

Combining high speed CMOS and monolithic transformer

technology, these isolation components provide outstanding

performance characteristics superior to alternatives such as the

combination of pulse transformers and non-isolated gate

drivers. By integrating the isolator and driver in a single

package, propagation delay is a maximum of only 64 ns, and the

propagation skew from channel to channel is a maximum of

only 12 ns at 12 V.

High-side or low-side relative to input: 565 V peak

High-side to low-side differential: 700 V peak

High frequency operation: 1 MHz maximum

Precise timing characteristics

64 ns maximum propagation delay

8.5 ns maximum channel-to-channel matching

3.0 V to 5.5 V input voltage

4.5 V to 18 V output drive

UVLO supply at 2.8 V V_DD1

A Version UVLO, V_DDAand V_DDB(V_DD2) at 4.1 V

B Version UVLO, V_DDAand V_DDBat 6.9 V

C Version UVLO, V_DDAand V_DDBat 10.5 V

CMOS input logic levels

High common-mode transient immunity: >25 kV/μs

High junction temperature operation: 125°C

Default low output

The ADuM7223 provides two independent isolation channels.

The ADuM7223 operates with an input supply ranging from 3.0 V

to 5.5 V, providing compatibility with lower voltage systems.

The outputs operate in a wide range from 4.5 V to 18 V with

three output voltage versions available. The 5 mm × 5 mm, LGA

package provides 565 V operating voltage from input to output

and 700 V from output to output.

5 mm × 5 mm, 13-terminal LGA

APPLICATIONS

In comparison to gate drivers employing high voltage level

translation methodologies, this gate driver offers the benefit of

true, galvanic isolation between the input and each output. As a

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.
