Analog Devices Inc. ADUM152N0BRZ-RL7

Overview

ADUM152N0BRZ-RL7 from Analog Devices is a 5-channel, 3.0 kV_RMS reinforced digital isolator based on iCoupler® transformer technology, featuring 150 Mbps guaranteed data rate, 13 ns max propagation delay at 5 V, and 1.8 V to 5.5 V dual-supply operation with level translation. It supports fail-safe high output state and operates across −40°C to +125°C for industrial motor control and isolated SPI interfaces.

For engineers reviewing the ADUM152N0BRZ-RL7 datasheet, ADUM152N0BRZ-RL7 pinout, ADUM152N0BRZ-RL7 application, or ADUM152N0BRZ-RL7 equivalent, key selection criteria include reinforced insulation rating (VIORM = 565 V_peak), channel-to-channel delay matching (≤4.0 ns), common-mode transient immunity (100 kV/µs), and SOIC_N-16 package compatibility with PCB creepage ≥4.0 mm.

Technical Context

The ADUM152N0BRZ-RL7 implements five independent unidirectional CMOS-isolated channels using monolithic air-core transformers, enabling dc-correct signal transmission without input transitions. Its architecture ensures deterministic timing behavior with pulse width distortion <4.5 ns and jitter as low as 70 ps_rms at 5 V operation.

It features dual independent supply domains (VDD1/VDD2), each supporting 1.7 V to 5.5 V, allowing bidirectional voltage translation across the isolation barrier. Fail-safe logic is implemented via internal circuitry that forces outputs high when either side's supply is absent - a defined behavior confirmed for the N0 variant in the Ordering Guide.

Key Specifications

Pinout & Package

ADUM152N0BRZ-RL7 is housed in a RoHS-compliant, narrow-body 16-lead SOIC (SOIC_N) package with 7.5 mm body width and 1.27 mm pitch. Input and output sides are physically separated by a 4.5 mm minimum PCB clearance gap.

FAQ

What is the fail-safe output behavior of ADUM152N0BRZ-RL7?

The ADUM152N0BRZ-RL7 is the N0 variant, meaning all five outputs default to logic high when either VDD1 or VDD2 is unpowered or below UVLO threshold (1.5 V). This behavior is internally implemented and does not require external pull-up resistors, ensuring predictable state during power sequencing or fault conditions in the ADUM152N0BRZ-RL7.

Does ADUM152N0BRZ-RL7 support bidirectional data flow?

No - ADUM152N0BRZ-RL7 provides five unidirectional channels (A–E) with fixed input-to-output directionality: Pins 1–5 are inputs (VDD1 side), Pins 9–13 are outputs (VDD2 side). For bidirectional protocols like I²C, separate isolators or alternative parts such as ADUM1250 must be used; the ADUM152N0BRZ-RL7 is optimized for SPI, PWM, and status signaling.

What safety certifications apply to ADUM152N0BRZ-RL7?

ADUM152N0BRZ-RL7 is certified to UL 1577 (3000 V_RMS), DIN EN IEC 60747-17 (VDE 0884-17) reinforced insulation (VIORM = 565 V_peak), IEC/CSA 62368-1, IEC/CSA 60601-1 (1 MOPP), and IEC/CSA 61010-1. These approvals are explicitly listed in Table 11 of the ADUM152N0BRZ-RL7 datasheet Rev. B and apply to the SOIC_N-16 package.

Can ADUM152N0BRZ-RL7 operate with mismatched supply voltages?

Yes - ADUM152N0BRZ-RL7 supports independent VDD1 and VDD2 supplies ranging from 1.7 V to 5.5 V each, enabling true level translation. For example, VDD1 = 1.8 V (microcontroller side) and VDD2 = 5 V (actuator side) is fully supported, with input thresholds scaling to 0.7×VDD1 and output drive capability defined relative to VDD2 - a core feature of the ADUM152N0BRZ-RL7.

What is the maximum continuous working voltage for ADUM152N0BRZ-RL7?

The maximum continuous working voltage for ADUM152N0BRZ-RL7 is 565 V_peak (reinforced insulation per VDE 0884-17) or 400 V_rms (basic insulation per IEC 62368-1). This value is specified in Table 15 and validated by partial discharge testing at 1059 V_peak; design margins must account for pollution degree 2 and altitudes ≤2000 m as defined in the ADUM152N0BRZ-RL7 regulatory documentation.
