Product details
Overview
ADUM7223CCCZ from Analog Devices is a 4.0 A isolated half-bridge gate driver with independent high-side and low-side outputs, 64 ns max propagation delay, 8.5 ns max channel-to-channel matching, and 565 V peak working voltage from input to output. It drives IGBTs and MOSFETs in high-voltage switching power supplies requiring galvanic isolation and precise timing.
For engineers reviewing the ADUM7223CCCZ datasheet, ADUM7223CCCZ pinout, ADUM7223CCCZ application, or ADUM7223CCCZ equivalent, this page delivers verified technical context, real-world design meaning of key specs, validated pin functions, confirmed alternatives, and supply support for industrial power conversion designs.
Technical Context
The ADUM7223CCCZ integrates iCoupler® monolithic transformer isolation with CMOS input logic and dual independent gate drive channels. It supports 3.0 V–5.5 V input supply and 4.5 V–18 V output drive, with C-grade UVLO thresholds at 10.5 V (rising) and 9.0 V (falling) on VDDA/VDDB.
It delivers true galvanic isolation between input and each output, enabling reliable control across ±700 V differential output voltage. Its 25 kV/μs common-mode transient immunity and 125°C junction temperature operation suit harsh industrial environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Output Current | 4.0 A - sufficient to directly drive high-Ciss IGBTs and fast-switching SiC MOSFETs without external buffers |
| Propagation Delay | 64 ns max - enables stable operation up to 1 MHz switching frequency with tight timing control |
| Channel-to-Channel Matching | 8.5 ns max - ensures symmetrical high-side/low-side turn-on/turn-off critical for shoot-through prevention |
| Input Voltage Range | 3.0 V to 5.5 V - compatible with 3.3 V and 5 V microcontrollers and FPGA I/O |
| VDDA/VDDB UVLO Threshold | 10.5 V (rising), 9.0 V (falling) - prevents erratic gate drive during brown-out conditions in 12 V–15 V gate supply rails |
| Isolation Working Voltage | 565 V peak (input-to-output), 700 V peak (output-to-output) - meets reinforced insulation requirements for 400 V AC and 600 V DC bus systems |
| Common-Mode Transient Immunity | >25 kV/μs - maintains signal integrity during fast dV/dt events in motor drives and inverters |
Pinout & Package
ADUM7223CCCZ uses a 5 mm × 5 mm, 13-terminal LGA package with exposed thermal pad (not electrically connected). Pin layout supports compact, high-density PCB routing while maintaining creepage/clearance ≥3.5 mm per safety standards.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 GND1 | Input-side ground reference | Return path for VIA/VIB logic inputs; must be separated from output grounds to preserve isolation barrier integrity |
| 2 VIA | High-side gate input | CMOS-compatible logic input controlling VOA output; referenced to GND1 |
| 3 VIB | Low-side gate input | CMOS-compatible logic input controlling VOB output; referenced to GND1 |
| 4, 6 NC | No connect | Not internally bonded; must remain unconnected and unstubbed on PCB |
| 5 DISABLE | Global output disable | Active-high signal forcing both VOA and VOB to logic low within 3 µs; used for fault shutdown and soft-start sequencing |
| 7 VDD1 | Input-side supply | Powers internal isolator logic; UVLO triggers at 2.8 V rising edge to prevent metastable behavior |
| 8 GNDB | Low-side output ground | Return path for VOB; electrically isolated from GND1 and GNDA |
| 9 VOB | Low-side gate output | Drives MOSFET/IGBT gate with 4.5 V–18 V swing; sink/source capable up to 4.0 A peak |
| 10 VDDB | Low-side output supply | Provides gate drive voltage for VOB; C-grade UVLO at 10.5 V ensures robust operation under load transients |
| 11 GNDA | High-side output ground | Return path for VOA; isolated from GND1 and GNDB; forms floating high-side reference |
| 12 VOA | High-side gate output | Drives high-side switch with same current capability and timing as VOB; referenced to GNDA |
| 13 VDDA | High-side output supply | Provides gate drive voltage for VOA; shares C-grade UVLO thresholds with VDDB |
Key Features
| Feature | Design Value |
|---|---|
| Galvanic isolation between input and outputs | Enables safe, noise-immune control of high-side switches referenced to floating potentials up to 700 V differential |
| Default-low output state | Ensures MOSFET/IGBT remains off during power-up, brown-out, or communication loss - critical for system safety |
| Thermal shutdown protection | Automatically disables outputs at 150°C junction temperature and recovers at ~140°C, preventing device destruction under overload |
| Refresh-based DC correctness | Maintains correct output logic state during static input conditions via periodic refresh pulses - no data loss over indefinite DC periods |
| Independent VDDA/VDDB UVLO | Allows asymmetric gate supply monitoring: high-side and low-side supplies can be independently validated before enabling drive |

Equivalent & Alternatives
The following parts are listed as comparable options for similar isolated half-bridge gate driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Si8233BD-D-IS | 3.3 A peak output, 120 ns max propagation delay, 20 kV/μs CMTI, SOIC-16 package | Limited to lower-power 400 V systems; lacks C-grade UVLO and tighter timing specs | Choose for cost-sensitive 3.3 A applications where 120 ns delay is acceptable and SOIC-16 layout is preferred |
| UCC21520CDW | 4.0 A peak, 35 ns max propagation delay, 150 V/ns CMTI, 16-pin SOIC with integrated Miller clamp | Higher CMTI but no C-grade UVLO; requires external bootstrap or isolated bias for high-side | Choose when ultra-low propagation delay and Miller clamping are required, and dual isolated supplies are available |
Compared with Si8233BD-D-IS and UCC21520CDW, ADUM7223CCCZ uniquely combines C-grade UVLO (10.5 V), 64 ns timing, and true dual isolated supplies in a compact LGA - making it optimal for high-reliability 600 V+ industrial inverters where supply margin and timing precision are critical.

FAQ
What is the UVLO threshold for VDDA and VDDB on ADUM7223CCCZ?
The ADUM7223CCCZ is the C-grade variant, with VDDA/VDDB undervoltage lockout thresholds of 10.5 V (rising edge) and 9.0 V (falling edge). This ensures gate drive remains disabled during brown-out conditions typical in 12 V–15 V auxiliary supplies feeding high-side and low-side drivers, preventing partial turn-on of power switches. The 0.9 V hysteresis provides noise margin against supply ripple.
Does ADUM7223CCCZ support independent high-side and low-side supply voltages?
Yes, ADUM7223CCCZ supports fully independent VDDA and VDDB supplies, each with its own C-grade UVLO (10.5 V rising, 9.0 V falling). This allows asymmetric gate drive configurations - for example, 15 V for high-side IGBTs and 12 V for low-side MOSFETs - while maintaining independent fault detection and safe shutdown per channel.
What is the maximum switching frequency supported by ADUM7223CCCZ?
ADUM7223CCCZ supports up to 1 MHz maximum data rate, validated at CL = 2 nF and VDD2 = 12 V. Its 64 ns max propagation delay and 8.5 ns max channel-to-channel matching enable stable PWM operation at 500 kHz–1 MHz in resonant converters and high-frequency inverters, provided layout minimizes parasitic inductance and gate loop area.
How does the DISABLE pin function on ADUM7223CCCZ?
The DISABLE pin on ADUM7223CCCZ is active-high: when asserted, it forces both VOA and VOB outputs to logic low within 3 µs, overriding input states. This provides hardware-level fault shutdown for overcurrent, overtemperature, or DC-link overvoltage events. During normal operation, DISABLE must be tied high (via pull-up) or driven actively to enable gate drive functionality.
What thermal derating applies to ADUM7223CCCZ at elevated ambient temperatures?
ADUM7223CCCZ has a junction-to-ambient thermal resistance (θJA) of 96.3°C/W. At 100°C ambient, with 1 W dissipation, junction temperature reaches ~200°C - exceeding the 150°C shutdown limit. Therefore, derating is essential: maximum safe power dissipation drops to ~0.52 W at 100°C ambient. Layout with thermal vias to inner ground planes and minimizing output trace inductance significantly improves real-world thermal performance.
