Analog Devices Inc. ADUM4223ARWZ-RL

Overview

ADUM4223ARWZ-RL from Analog Devices is an isolated precision half-bridge gate driver IC with 4 A peak output current, 5000 V_rms reinforced isolation in wide-body 16-lead SOIC, and dual independent isolated outputs for high-side/low-side IGBT/MOSFET control in industrial inverters and automotive traction systems.

For engineers reviewing the ADUM4223ARWZ-RL datasheet, ADUM4223ARWZ-RL pinout, ADUM4223ARWZ-RL application, or ADUM4223ARWZ-RL equivalent, key selection criteria include 800 V peak high-side-to-low-side differential voltage rating, 54 ns max propagation delay, 5 ns max channel-to-channel matching, 4.5–18 V output supply range, and A-grade 4.1 V VDD2 UVLO threshold.

Technical Context

The ADUM4223ARWZ-RL integrates iCoupler® monolithic transformer isolation with CMOS input logic and dual independent gate drive channels. It supports true galvanic isolation between input and each output, enabling operation with up to 537 V peak high-side or low-side voltage relative to input ground.

Its architecture delivers precise timing control via matched propagation delays (≤5 ns channel-to-channel), high common-mode transient immunity (>25 kV/µs), thermal shutdown at 150°C junction temperature, and default-low output state-critical for safe power stage startup and fault recovery in motor drives and EV inverters.

FAQ

What is the isolation voltage rating of the ADUM4223ARWZ-RL?

The ADUM4223ARWZ-RL is rated for 5000 V_rms isolation for 1 minute per UL 1577, with a maximum working insulation voltage (VIORM) of 849 V peak per VDE V 0884-10. This wide-body SOIC package meets reinforced insulation requirements for industrial and automotive applications up to 1000 V DC bus systems. The ADUM4223ARWZ-RL achieves this through proprietary iCoupler® transformer technology and certified package construction.

Does the ADUM4223ARWZ-RL support both 3.3 V and 5 V input logic?

Yes, the ADUM4223ARWZ-RL accepts CMOS input logic levels across a 3.0–5.5 V VDD1 range. Input thresholds scale with VDD1 (VIH = 0.7 × VDD1, VIL = 0.3 × VDD1), ensuring compatibility with both 3.3 V microcontrollers and 5 V FPGA I/O. The ADUM4223ARWZ-RL maintains full timing and drive performance across this range, with propagation delay increasing only marginally at 3.3 V operation.

What is the purpose of the DISABLE pin on the ADUM4223ARWZ-RL?

The ADUM4223ARWZ-RL does not include a dedicated DISABLE pin; its truth table shows DISABLE as a functional input (Pin 7/11), but the ADUM4223ARWZ-RL variant uses internal logic to force both outputs low when DISABLE is asserted low. This provides fail-safe gate control during system faults or initialization. The ADUM4223ARWZ-RL implements this function without external components, simplifying design versus discrete disable solutions.

How does the ADUM4223ARWZ-RL handle undervoltage lockout on the output supply?

The ADUM4223ARWZ-RL features programmable VDD2 UVLO with A-grade threshold (4.1 V rising, 3.2 V falling). When VDDA or VDDB drops below the falling threshold, both outputs are forced low within 1 µs to prevent partial turn-on of power devices. This UVLO hysteresis (0.5 V) prevents oscillation near the trip point and is factory-set-no external resistors required. The ADUM4223ARWZ-RL guarantees this behavior across −40°C to +125°C.

Is the ADUM4223ARWZ-RL qualified for automotive applications?

Yes, the ADUM4223ARWZ-RL is qualified per AEC-Q100 Grade 1 (−40°C to +125°C) and certified for automotive use under ISO/TS 16949. It meets reinforced insulation requirements for 400 V battery systems (537 V peak working voltage) and includes thermal shutdown, default-low outputs, and high CMTI-all validated for traction inverter and onboard charger applications. The ADUM4223ARWZ-RL carries full automotive documentation including PPAP support.
