Analog Devices Inc. ADUM4223WCRWZ-RL

Overview

ADUM4223WCRWZ-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 ADUM4223WCRWZ-RL datasheet, ADUM4223WCRWZ-RL pinout, ADUM4223WCRWZ-RL application, or ADUM4223WCRWZ-RL equivalent, key selection criteria include 800 V peak high-side-to-low-side differential voltage, 54 ns max propagation delay, 7.0 V VDD2 UVLO (B-grade), 125°C junction operation, and VDE-certified 849 V_peak working voltage compliance.

Technical Context

The ADUM4223WCRWZ-RL integrates iCoupler® monolithic transformer isolation with CMOS input logic and independent high-side/low-side gate drive outputs. It supports 3.3 V to 5 V input logic and 4.5 V to 18 V output supply ranges, enabling compatibility with both low-voltage controllers and high-voltage power stages.

Its architecture delivers true galvanic isolation between input and each output channel, allowing continuous operation up to 537 V_peak relative to input ground and supporting bootstrapped or floating high-side configurations with up to 800 V_peak differential voltage across the bridge.

FAQ

What is the isolation voltage rating of the ADUM4223WCRWZ-RL?

The ADUM4223WCRWZ-RL is rated for 5000 V_rms isolation for 1 minute per UL 1577 and carries VDE certification with a maximum working insulation voltage (VIORM) of 849 V_peak. This reinforced isolation rating enables safe operation in high-voltage industrial and automotive applications where galvanic separation between control and power domains is critical. The ADUM4223WCRWZ-RL achieves this using Analog Devices' proprietary iCoupler® technology.

Does the ADUM4223WCRWZ-RL support 3.3 V microcontroller inputs?

Yes, the ADUM4223WCRWZ-RL accepts 3.3 V CMOS input logic levels with VIH = 0.7 × VDD1 and VIL = 0.3 × VDD1, supporting VDD1 supply voltages from 3.0 V to 5.5 V. When VDD1 = 3.3 V, the input high threshold is 2.31 V and low threshold is 0.99 V - fully compatible with standard 3.3 V microcontrollers and FPGAs. The ADUM4223WCRWZ-RL maintains full timing and drive performance across this input range.

What is the purpose of the DISABLE pin on the ADUM4223WCRWZ-RL?

Pin 9 (DISABLE) on the ADUM4223WCRWZ-RL provides a hardware fault-shutdown function: when driven low, it forces both VOA and VOB outputs to logic low regardless of input states, ensuring safe turn-off of the power stage during overcurrent, overtemperature, or system fault conditions. This feature is essential for functional safety compliance in automotive and industrial inverters. The ADUM4223WCRWZ-RL implements this with internal logic that overrides normal operation without requiring external pull-down resistors.

How does the ADUM4223WCRWZ-RL handle undervoltage conditions on its output supply rails?

The ADUM4223WCRWZ-RL includes programmable VDD2 undervoltage lockout (UVLO) with three grade options: A (4.1 V), B (6.9 V), and C (10.5 V). The ADUM4223WCRWZ-RL is a B-grade part, meaning it asserts UVLO when VDDA or VDDB falls below 6.9 V (rising edge) and releases above 7.4 V, with 0.7 V hysteresis. This prevents unreliable gate drive during insufficient gate supply voltage - critical for preventing partial turn-on and shoot-through in high-power bridges.

Can the ADUM4223WCRWZ-RL drive SiC MOSFETs directly?

Yes, the ADUM4223WCRWZ-RL delivers 4 A peak source/sink current with <12 ns rise/fall times into a 2 nF load, making it suitable for direct driving of medium-power SiC MOSFETs (e.g., up to 1200 V/50 A devices with Qg < 100 nC). Its 800 V_peak high-side-to-low-side differential rating and >25 kV/µs CMTI further support fast-switching SiC topologies. The ADUM4223WCRWZ-RL's thermal shutdown at 150°C also protects against gate driver overheating during high-frequency SiC operation.
