Precise timing characteristics

GENERAL DESCRIPTION

The ADuM3223/ADuM4223¹are 4 A isolated, half-bridge

gate drivers that employ the Analog Devices, Inc., iCoupler®

technology to provide independent and isolated high-side

and low-side outputs. The ADuM3223 provides 3000 V rms

isolation in the narrow body, 16-lead SOIC package, and the

ADuM4223 provides 5000 V rms isolation in the wide body,

16-lead SOIC package. Combining high speed CMOS and

monolithic transformer technology, these isolation components

provide outstanding performance characteristics superior to the

alternatives, such as the combination of pulse transformers and

gate drivers.

49 ns maximum isolator and driver propagation delay

5 ns maximum channel-to-channel matching

CMOS input logic levels

The ADuM3223/ADuM4223 isolators each provide two

independent isolated channels. They operate with an input

supply ranging from 3.0 V to 5.5 V, providing compatibility

with lower voltage systems. In comparison to gate drivers

employing high voltage level translation methodologies, the

ADuM3223/ADuM4223 offer the benefit of true, galvanic

isolation between the input and each output. Each output may

be continuously operated up to 560 V_PEAKrelative to the input,

thereby supporting low-side switching to negative voltages. The

differential voltage between the high-side and low-side may be

High common-mode transient immunity: >50 kV/µs

Enhanced system-level ESD performance per IEC 61000-4-x

High junction temperature operation: 125°C

Default low output

Safety and regulatory approvals (pending)

ADuM3223 narrow body, 16-lead SOIC

UL 1577 3000 V rms input-to-output withstand voltage

ADuM4223 wide body, 16-lead SOIC

UL 1577 5000 V rms input-to-output withstand voltage

as high as 700 V_PEAK.

As a result, the ADuM3223/ADuM4223 provide reliable

control over the switching characteristics of IGBT/MOSFET

configurations over a wide range of positive or negative

switching voltages.

APPLICATIONS

Switching power supplies

Isolated IGBT/MOSFET gate drives
