Isolated Precision Gate Driver,

4.0 A Output

Data Sheet

ADuM3123

FEATURES

GENERAL DESCRIPTION

4.0 A output short-circuit pulsed current

Isolated working voltage

Secondary side to input side: 537 V

High frequency operation: 1 MHz maximum

3.3 V to 5 V input logic

4.5 V to 18 V output drive

Undervoltage lockout (UVLO): 2.8 V V_DD1

Precise timing characteristics

The ADuM3123¹is a 4.0 A isolated, single channel driver that

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

precision isolation. The ADuM3123 provides 3000 V rms

isolation in the narrow-body, 8-lead SOIC package. 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 gate drivers.

64 ns maximum isolator and driver propagation delay

Complementary metal oxide semiconductor (CMOS) input

logic levels

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

High junction temperature operation: 125°C

Default low output

The ADuM3123 operates 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 ADuM3123 offers the

benefit of true, galvanic isolation between the input and the

output. The output can continuously operate up to 380 V rms

relative to the input.

Safety and regulatory approvals (pending)

UL recognition per UL 1577

As a result, the ADuM3123 provides reliable control over the

switching characteristics of IGBT/MOSFET configurations over

a wide range of positive and negative switching voltages.

3000 V rms for 1 minute SOIC long package

CSA Component Acceptance Notice 5A

VDE certificate of conformity (pending)

DIN V VDE V 0884-10 (VDE V 0884-10):2006-12

Maximum working insulation voltage (V_IORM) = 560 V peak

Narrow body, 8-lead SOIC

APPLICATIONS

Switching power supplies

Isolated gate bipolar transistors (IGBT)/MOSFET gate drives

Industrial inverters
