Product details
Overview
ADUM1420BRWZ from Analog Devices is a quad-channel isolated gate driver IC with independent galvanic isolation between input and each of four outputs, 0.1 A peak output current per channel, ±700 V peak input-to-output differential voltage, and 5 Mbps maximum switching frequency. It supports high-side/low-side IGBT and MOSFET driving in industrial motor inverters requiring robust common-mode transient immunity.
For engineers reviewing the ADUM1420BRWZ datasheet, ADUM1420BRWZ pinout, ADUM1420BRWZ application, or ADUM1420BRWZ equivalent, this device delivers precise timing control, channel-to-channel matching under 13 ns, and operation up to +105°C in wide-body SOIC packaging for high-voltage power stage isolation.
Technical Context
The ADUM1420BRWZ integrates iCoupler® digital isolation with independent isolated output supplies (VDDA–VDDD), enabling simultaneous high-side and low-side gate drive without level-shifting circuitry. Its error detection disable (ED DISABLE) pin allows deterministic logic propagation during fault conditions.
Each output channel features matched propagation delay (tPHL/tPLH ≤ 128 ns), pulse width distortion < 8 ns, and >75 kV/μs common-mode transient immunity across all isolation barriers - input-to-output, output-to-output, and supply-to-supply - ensuring reliable operation in noisy 600 V+ DC bus environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channels | 4 independent isolated gate drive outputs (A–D) |
| Peak Output Current | 0.1 A per channel - sufficient to drive medium-power IGBTs and MOSFETs directly |
| Input-to-Output Isolation | ±700 V peak - supports gate driving referenced to negative rails or floating topologies |
| Max Switching Frequency | 5 Mbps - enables PWM control up to 2.5 MHz with clean edge integrity |
| Propagation Delay | 99–128 ns - tight timing budget for synchronous multi-phase gate control |
| CM Transient Immunity | >75 kV/μs - maintains signal integrity during fast dV/dt transients in motor drives |
| Operating Temperature | −40°C to +105°C - qualified for industrial and automotive under-hood environments |
| Supply Voltages | VDD1 = 4.5–5.5 V; VDDA–VDDD = 12–18 V - decoupled logic and power domains |
Pinout & Package
ADUM1420BRWZ uses a wide-body 28-lead SOIC package (RW-28, JEDEC MS-013-AE), with 14 pins on each side forming two isolated domains: Pins 1–14 for input and output A/B, Pins 15–28 for outputs C/D and shared grounds. Internal connections exist between Pins 7/14 (GND1) and Pins 20/23 (GNDC); NC pins (4–6, 18–19, 24–25) must remain unconnected.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8, 9–13, 14 | Input domain (logic side) | Pins 1/14 = GND1; Pin 8 = VDD1; Pins 9–12 = VIA–VID; Pin 13 = ED DISABLE |
| 2, 3, 15–17, 21, 22, 26–28 | Output domain (isolated power side) | Per-channel VDDx/GNDA–GNDD/VOx pairs enable independent biasing of four gate drivers |
| 4–6, 18, 19, 24, 25 | No Connect | Floating pins - must be left unconnected per datasheet to avoid parasitic coupling |
Key Features
| Feature | Design Value |
|---|---|
| Galvanic isolation per channel | Eliminates need for external level shifters or bootstrap circuits in half-bridge and three-phase inverter designs |
| Channel-to-channel matching | Rising/falling edge skew ≤13 ns - enables precise dead-time control across multiple phases |
| Error detection disable (ED DISABLE) | Allows forced pass-through mode during system fault recovery without output latching |
| High CMTI (>75 kV/μs) | Prevents false triggering in high-dV/dt environments such as SiC-based motor drives |
| Wide output supply range (12–18 V) | Supports gate drive for both 15 V IGBTs and 12 V logic-level MOSFETs without external regulators |
Applications
| Industrial Motor Inverters | Plasma Display Modules |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad isolated gate driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Si8261ACD-C-ISR | Higher 4 A peak output current; 2.5 kVrms isolation rating; 10 MHz max data rate; different pinout and supply architecture (single VDDA/VDDA pair) | Better suited for direct high-current SiC MOSFET driving; less flexible for mixed-voltage gate biasing | Select when higher drive strength and faster switching are required, and layout can accommodate revised pin mapping |
| ISO5852SMDWR | Reinforced 5.7 kVrms isolation; 2.5 A peak output; integrated Miller clamp; single-input dual-output topology (not quad independent) | Optimized for half-bridge configurations with built-in protection; lacks four fully independent channels | Choose for compact half-bridge gate driving with enhanced safety certification, not for discrete quad-channel control |
Compared with Si8261ACD-C-ISR and ISO5852SMDWR, ADUM1420BRWZ provides true four-channel independence with configurable per-channel supplies and lower drive strength - ideal for applications requiring precise timing alignment across multiple isolated power domains rather than raw current delivery or integrated protection.

FAQ
What is the maximum output supply voltage supported by ADUM1420BRWZ?
The ADUM1420BRWZ supports output supply voltages from 12 V to 18 V per channel (VDDA–VDDD). Absolute maximum rating is +27 V, but operation above 18 V is not characterized and may compromise timing performance or reliability. For sustained 15 V gate drive in IGBT applications, ADUM1420BRWZ operates within its recommended range with full specification compliance.
Does ADUM1420BRWZ provide internal Miller clamp functionality?
No, ADUM1420BRWZ does not include an internal Miller clamp. It delivers standard push-pull gate drive outputs (VOA–VOD) with logic-level compatible inputs and no integrated active pull-down during switching transitions. External Miller clamps or dedicated gate driver ICs with clamp features (e.g., ISO5852S) are required if Miller-induced turn-on prevention is needed in high-dV/dt applications.
Can ADUM1420BRWZ drive both high-side and low-side switches simultaneously in a half-bridge configuration?
Yes, ADUM1420BRWZ can drive both high-side and low-side switches simultaneously in a half-bridge configuration. Its four independent isolated outputs allow assignment of VOx channels to separate high-side and low-side gates, with each output having its own isolated supply (VDDx/GNDx) - enabling true floating high-side drive without bootstrap components.
What is the purpose of the ED DISABLE pin on ADUM1420BRWZ?
The ED DISABLE pin (Pin 13) disables the internal error detection circuitry in ADUM1420BRWZ. When pulled high or left floating (NC), it forces the outputs to mirror the inputs regardless of internal refresh status, eliminating potential output glitches during power sequencing or fault recovery. This ensures deterministic behavior when system-level supervision overrides isolation monitoring.
Is ADUM1420BRWZ rated for reinforced insulation?
No, ADUM1420BRWZ is rated for basic insulation only, with UL recognition at 1667 V rms for 1 minute (UL 1577). It is not certified for reinforced insulation per IEC 60747-5-5 or VDE 0884-10. For applications requiring reinforced isolation (e.g., medical or EV charging), designers must verify system-level creepage/clearance and consider alternatives like ADUM4223 or ISO5852S with reinforced ratings.
