Product details
Overview
ADUM1233BRWZ-RL from Analog Devices is an isolated, precision half-bridge gate driver IC with independent high-side and low-side outputs, ±700 VPEAK input-to-output isolation voltage, 0.1 A peak output current, 5 MHz maximum switching frequency, and >75 kV/µs common-mode transient immunity-designed for reliable IGBT/MOSFET control in industrial inverters and switching power supplies.
For engineers reviewing the ADUM1233BRWZ-RL datasheet, ADUM1233BRWZ-RL pinout, ADUM1233BRWZ-RL application, or ADUM1233BRWZ-RL equivalent, this page delivers verified specifications, functional pin mapping, real-world use cases, and validated alternative options for gate drive isolation in high-voltage, high-noise environments.
Technical Context
The ADUM1233BRWZ-RL integrates iCoupler® monolithic transformer isolation to replace optocouplers, delivering precise timing with <124 ns propagation delay and <8 ns pulse width distortion. Its dual-channel architecture supports independent logic inputs (VIA/VIB) and separate high-side (VOA/VDDA/GNDA) and low-side (VOB/VDDB/GNDB) output domains.
Each output channel operates up to ±700 VPEAK relative to input ground (GND1), enabling negative low-side switching; differential high-side/low-side voltage withstand is rated at 700 VPEAK. The device features a dedicated DISABLE pin that forces both outputs low, and uses 4.5–5.5 V input supply (VDD1) with 12–18 V output supplies (VDDA/VDDB).

Pinout & Package
ADUM1233BRWZ-RL is housed in a wide-body 16-lead SOIC package (JEDEC MS-013-AA, RW-16), with 3.5 mm minimum creepage and clearance between input and output sides. Input side (Pins 1–8) and output side (Pins 9–16) are galvanically isolated; Pins 3 & 8 are internally connected to VDD1; Pins 6, 7, 12, 13 are no-connect.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIA (Pin 1) | Logic Input A | Controls high-side output VOA; accepts 5 V CMOS-level signals |
| VIB (Pin 2) | Logic Input B | Controls low-side output VOB; independent of VIA for half-bridge dead-time control |
| VDD1 (Pins 3, 8) | Input Supply | 4.5–5.5 V power for input logic and isolation interface; dual-pin connection improves noise immunity |
| GND1 (Pin 4) | Input Ground | Reference for VIA, VIB, and DISABLE; must be separated from output grounds |
| DISABLE (Pin 5) | Active-Low Enable | Pulls both VOA and VOB low when asserted; used for fault shutdown or safe startup sequencing |
| VDDA (Pin 16) | High-Side Output Supply | 12–18 V supply for VOA; referenced to GNDA; powers gate drive stage |
| VOA (Pin 15) | High-Side Output | Drives IGBT/MOSFET gate referenced to GNDA; capable of sourcing/sinking 0.1 A peak |
| GNDA (Pin 14) | High-Side Ground | Return path for VDDA and VOA; floats up to ±700 VPEAK relative to GND1 |
| VDDB (Pin 11) | Low-Side Output Supply | 12–18 V supply for VOB; referenced to GNDB; electrically isolated from VDDA |
| VOB (Pin 10) | Low-Side Output | Drives complementary switch; operates with independent ground GNDB |
| GNDB (Pin 9) | Low-Side Ground | Return path for VDDB and VOB; may be tied to system ground or biased negative |

Equivalent & Alternatives
The following parts are listed as comparable options for similar isolated half-bridge gate drive applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Si8233BD-D-IS | Capable of 0.6 A peak output current; uses capacitive isolation; higher drive strength but larger propagation delay (150 ns typical) | Better suited for driving high-gate-charge SiC MOSFETs; less optimal for ultra-fast timing-critical topologies | Select when higher output current is required and timing skew tolerance exceeds 15 ns |
| ISO5852SMDWR | Reinforced isolation (5000 Vrms), 2.5 A peak output, integrated Miller clamp; requires external bootstrap or isolated supply for high-side | Targets high-power traction inverters; includes protection features not present in ADUM1233BRWZ-RL | Choose for automotive-grade systems needing active Miller clamping and higher drive capability |
Compared with Si8233BD-D-IS and ISO5852SMDWR, the ADUM1233BRWZ-RL offers superior timing precision (≤8 ns PWD) and lower drive current in a compact SOIC_W package-making it ideal for space-constrained industrial inverters where timing accuracy outweighs raw drive strength.

FAQ
What is the maximum recommended output supply voltage for ADUM1233BRWZ-RL?
The ADUM1233BRWZ-RL specifies a recommended operating range of 12 V to 18 V for both VDDA and VDDB. Absolute maximum rating is 27 V, but sustained operation above 18 V risks exceeding thermal limits and degrading long-term reliability. Designers should maintain VDDA/VDDB within 15 ± 1.5 V for optimal timing performance and safety margin.
Does ADUM1233BRWZ-RL support negative voltage on the low-side ground (GNDB)?
Yes. The ADUM1233BRWZ-RL allows GNDB to operate at voltages up to −700 VPEAK relative to GND1, enabling configurations such as negative-bias gate driving for enhanced turn-off robustness in high-side IGBT applications. This is explicitly confirmed in the Absolute Maximum Ratings table and General Description section of the datasheet.
Can ADUM1233BRWZ-RL drive SiC MOSFETs directly?
The ADUM1233BRWZ-RL provides 0.1 A peak output current and 25 ns rise/fall times-sufficient for low-to-medium gate charge SiC MOSFETs (Qg < 20 nC) in sub-10 kW applications. For higher Qg devices or faster switching (>200 kHz), external gate resistors or buffer stages are recommended to ensure adequate dV/dt control and minimize ringing.
What is the purpose of the DISABLE pin on ADUM1233BRWZ-RL?
The DISABLE pin (Pin 5) is an active-low control that forces both VOA and VOB outputs into a low state regardless of VIA/VIB inputs. It is used for system-level fault handling, safe startup sequencing, or emergency shutdown-ensuring both switches remain off during controller reset or overcurrent events without relying on upstream logic states.
Is ADUM1233BRWZ-RL pin-compatible with other ADuM123x variants?
Yes. ADUM1233BRWZ-RL shares identical pinout, package (RW-16), and functional block diagram with ADUM1230/ADUM1231/ADUM1232 in the same family. Differences lie in truth table behavior (e.g., ADUM1230 has non-inverting outputs, ADUM1233 uses positive logic per Table 9), but PCB layout and footprint are fully interchangeable.
