ADUM3123ARZ

Isolators - Gate Drivers Overview

The ADUM3123ARZ is a single-channel, galvanically isolated precision gate driver from Analog Devices. It utilizes iCoupler technology to provide high-speed signal isolation within an SOIC-8 package. The device delivers a peak output current of 4 A and supports output voltages ranging from 4.5 V to 18 V. Key electrical parameters include rise and fall times of 12 ns, a maximum power dissipation of 1.31 W, and a quiescent supply current of 5.6 mA. It operates reliably across a temperature range of -40°C to +125°C.

Isolators - Gate Drivers Feature Summary

• Employs iCoupler technology for precise galvanic isolation without magnetic components
• Provides high-speed switching with symmetric 12 ns rise and fall times
• Features a shutdown function for controlled output disablement
• Supports inverting logic configuration for flexible circuit integration

Isolators - Gate Drivers Applications

• Driving isolated gate bipolar transistors (IGBTs)
• Switching metal-oxide-semiconductor field-effect transistors (MOSFETs)
• Power management integrated circuits requiring signal isolation
• Evaluation using the EVAL-ADUM3123EBZ reference design

Isolators - Gate Drivers Procurement Notes

Verify component authenticity through authorized Analog Devices channels or certified distributors. Confirm the specific suffix ARZ corresponds to the tube packaging variant rather than reel configurations. Ensure compliance with RoHS standards and check moisture sensitivity levels prior to surface mount assembly processes.

Isolators - Gate Drivers Selection Notes

Select this model when a minimum output voltage as low as 4.4 V is required compared to other variants in the series. Consider the SOIC-8 footprint and SMD/SMT installation style for board space constraints. Evaluate the 4 A drive capability against the target power device requirements to ensure adequate switching performance.

Isolators - Gate Drivers Part Context

This component belongs to the ADUM3123 series of isolated gate drivers. It serves as a superset within the family due to its lower minimum output voltage specification compared to the ADUM3123BRZ and ADUM3123CRZ models. The device is categorized under PMIC and Galvanically Isolated Gate Drivers.

Isolators - Gate Drivers Replacement Considerations

Public confirmed substitutes include ADUM3123BRZ and ADUM3123CRZ. Note that these alternatives have higher minimum output voltages of 7.4 V and 11.1 V respectively, which may affect compatibility with certain low-voltage gate drive applications.
