Analog Devices Inc. ADUM5200CRWZ-RL

Overview

ADUM5200CRWZ-RL from Analog Devices is a dual-channel, 2.5 kV rms digital isolator with integrated isoPower® DC-to-DC converter delivering regulated 5 V or 3.3 V isolated output up to 500 mW, supporting data rates up to 25 Mbps (NRZ), and housed in a 16-lead SOIC package with 7.6 mm creepage. It enables isolated RS-485 transceiver biasing and industrial PLC sensor interfaces without external isolated power.

For engineers reviewing the ADUM5200CRWZ-RL datasheet, ADUM5200CRWZ-RL pinout, ADUM5200CRWZ-RL application, or ADUM5200CRWZ-RL equivalent, key selection criteria include integrated 500 mW isolated power delivery, 25 Mbps signal isolation, 2.5 kV rms UL/VDE-rated insulation, −40°C to +105°C operation, and dual-channel directional configuration (VIA→VOA, VIB→VOB).

Technical Context

The ADUM5200CRWZ-RL implements iCoupler® chip-scale transformer technology for both signal isolation and magnetic energy transfer in its integrated DC-to-DC converter. Its dual independent channels are unidirectional (input-side pins 3/4 → output-side pins 14/13), with internal regulation controlled by VSEL (pin 11) and RCSEL (pin 6) to select 5 V or 3.3 V VISO output.

It features active refresh circuitry maintaining DC correctness, high common-mode transient immunity (>25 kV/µs), and thermal shutdown at 150°C. The device operates across 3.0–5.5 V primary supply and supports self-regulation or slave-mode configuration via RCIN/RCSEL pins - critical for multi-isolator power tree designs.

Key Specifications

Pinout & Package

ADUM5200CRWZ-RL uses a 16-lead SOIC wide-body (RW-16) package with gull-wing leads, 7.6 mm minimum creepage, and internal shorting of GND1 (pins 2 & 8) and GNDISO (pins 9 & 15). Pin 1 is VDD1; pin 16 is VISO. No exposed pad.

FAQ

What is the maximum continuous output current from VISO on the ADUM5200CRWZ-RL?

The ADUM5200CRWZ-RL delivers up to 100 mA from VISO when configured for 5 V output with 5 V input, and up to 60 mA when configured for 3.3 V output with 3.3 V input. At 5 V input / 3.3 V output, it supports 100 mA load. These values are specified in Tables 3, 7, and 11 of the datasheet and reflect the maximum current before VISO drops below regulation threshold. Derating applies above 85°C ambient.

Can the ADUM5200CRWZ-RL operate with a 3.3 V primary supply and deliver 5 V isolated output?

No. The ADUM5200CRWZ-RL cannot generate 5 V isolated output from a 3.3 V primary supply. Its isoPower architecture requires VDD1 ≥ VISO; VSEL selects between 3.3 V (VSEL = GNDISO) or 5 V (VSEL = VISO) output, but only when VDD1 is 4.5–5.5 V. With 3.3 V VDD1, VISO is fixed at 3.3 V regardless of VSEL state - confirmed in Table 6 and the General Description section.

What is the function of the VE2 pin on the ADUM5200CRWZ-RL?

The VE2 pin (Pin 10) is an active-high output enable for the isolated side. When VE2 is high or left floating, VOA and VOB drive their respective logic states normally. When VE2 is pulled low, both outputs enter high-impedance (high-Z) state - useful for bus arbitration, power sequencing, or disabling isolated peripherals during standby. This behavior is defined in Table 21 and Figure 1 of the datasheet.

Does the ADUM5200CRWZ-RL require external components for DC-DC regulation?

The ADUM5200CRWZ-RL requires only two external bypass capacitors: 0.1 µF and 10 µF (X7R ceramic) on VISO (Pin 16) and matching 0.1 µF on VDD1 (Pin 1), as specified in Figure 23 and the Applications Information section. No inductors, transformers, or feedback resistors are needed - regulation is fully integrated and internally compensated.

How does the ADUM5200CRWZ-RL handle undervoltage lockout conditions?

The ADUM5200CRWZ-RL implements independent undervoltage lockout (UVLO) on VDD1, VISO, and VDD1-related supplies, with positive-going threshold at 2.7 V and hysteresis of 0.3 V. If VDD1 falls below 2.4 V, all outputs disable and isoPower shuts down; recovery occurs only after VDD1 exceeds 2.7 V. This prevents metastable operation and ensures clean power-up sequencing - detailed in Table 5 and Table 9.
