Analog Devices Inc. ADUM6132ARWZ-RL

Overview

ADUM6132ARWZ-RL from Analog Devices is an isolated half-bridge gate driver with integrated isoPower® high-side DC-DC supply, delivering 275 mW at 12.5–17 V output, supporting ±200 mA peak output current per channel, and featuring >50 kV/µs common-mode transient immunity. It drives MOSFETs/IGBTs in high-voltage motor drives and solar inverters where galvanic isolation and self-powered high-side operation are critical.

For engineers reviewing the ADUM6132ARWZ-RL datasheet, ADUM6132ARWZ-RL pinout, ADUM6132ARWZ-RL application, or ADUM6132ARWZ-RL equivalent, key selection criteria include isolated high-side supply capability, channel-to-channel timing matching (≤20 ns), reinforced insulation rating (VIORM = 560 V peak), UL/CSA/VDE safety approvals, and SOIC-16 wide-body package compatibility with 8.0 mm creepage/clearance.

Technical Context

The ADUM6132ARWZ-RL integrates iCoupler® digital isolation with an on-chip isolated DC-DC converter that powers the high-side output stage (VOA) and external buffer circuitry via VISO (12.5–17 V). Its architecture separates control-side (VDD/VDDL/VIA/VIB) and power-side (VDDA/VDDB/GNDA/GNDISO) domains with independent UVLO on all three supplies.

Timing performance is tightly controlled: propagation delay (40–100 ns), pulse width distortion ≤10 ns, and channel-to-channel matching ≤20 ns for same-edge transitions. The device supports up to 1 MHz switching frequency with 50 ns minimum pulse width and operates across −40°C to +85°C ambient temperature.

FAQ

What is the maximum continuous output current supported by the ADUM6132ARWZ-RL high-side channel?

The ADUM6132ARWZ-RL supports ±200 mA peak output current on both VOA and VOB channels for durations under 1 second. For continuous operation, average DC output current is limited to ±10 mA per channel. The integrated isolated supply delivers up to 22 mA net current (after powering VDDA), enabling external buffer circuits while maintaining thermal safety within the SOIC_W package.

Does the ADUM6132ARWZ-RL require external components to generate its isolated high-side supply?

No - the ADUM6132ARWZ-RL includes an integrated isoPower® isolated DC-DC converter that generates VISO (12.5–17 V) from the logic-side VDD supply. External components are limited to recommended bypass capacitors (0.1 µF + 10 µF on VDD/VISO), with no need for transformers, diodes, or bootstrap capacitors typically required in alternative gate driver architectures.

How does the ADUM6132ARWZ-RL handle undervoltage conditions on its power rails?

The ADUM6132ARWZ-RL implements independent undervoltage lockout (UVLO) on VDDL (3.5–3.8 V threshold), VDDA (11.0–12.3 V), and VDDB (11.0–12.3 V). When any supply falls below its UVLO threshold, the corresponding output is forced low. This prevents undefined gate states during power-up, brownout, or fault conditions - a critical safeguard in high-voltage power conversion systems.

Can the ADUM6132ARWZ-RL drive high-gate-charge SiC or GaN FETs directly?

The ADUM6132ARWZ-RL is specified for driving low-capacitance devices (≤200 pF typical), such as small IGBTs or low-V_DS MOSFETs. For high-gate-charge SiC/GaN FETs, Analog Devices recommends using the ADUM6132ARWZ-RL to drive an external buffer stage (e.g., dual MOSFET driver), leveraging its VISO supply to power that buffer - a configuration validated in Figure 16 of the datasheet.

What safety certifications apply to the ADUM6132ARWZ-RL and how do they impact system-level compliance?

The ADUM6132ARWZ-RL holds UL 1577 (3750 V rms, 1 min), CSA 60950-1 (400 V rms basic / 250 V rms reinforced), and DIN V VDE V 0884-10 (560 V peak reinforced) certifications. These allow direct use in end equipment targeting IEC 62368-1 and IEC 60747-17 without additional isolation barrier validation - reducing time-to-certification for industrial and renewable energy inverters.
