Product details
Overview
ADuM5202CRWZ from Analog Devices is a dual-channel, 2.5 kV rms digital isolator with integrated isoPower® DC-to-DC converter delivering regulated 3.3 V or 5.0 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 compact isolated power + signal transfer in RS-485 transceivers and industrial PLCs.
For engineers reviewing the ADuM5202CRWZ datasheet, ADuM5202CRWZ pinout, ADuM5202CRWZ application, or ADuM5202CRWZ equivalent, key selection criteria include isolated supply voltage configuration (3.3 V/5.0 V), channel directionality (VOA/VIB input-side vs. VOA/VOB output-side), propagation delay skew ≤15 ns (C grade), common-mode transient immunity >25 kV/µs, and UL/VDE-reinforced insulation compliance.
Technical Context
The ADuM5202CRWZ implements iCoupler® chip-scale transformer technology for both signal isolation and magnetic power transfer, eliminating external isolated DC-DC converters. Its isoPower core operates at 180 MHz switching frequency with 625 kHz PWM modulation, enabling up to 500 mW output while maintaining <75 mVp-p ripple at full load.
It features two independent unidirectional channels with fixed input-to-output directionality (VIA→VOA, VIB→VOB), undervoltage lockout (2.4 V–2.7 V thresholds), and thermal shutdown at 150°C. Pin configuration supports self-regulation (RCSEL = high) or slave-mode operation (RCSEL = low), with VSEL selecting 3.3 V (GNDISO) or 5.0 V (VISO) isolated output.

Pinout & Package
ADuM5202CRWZ uses a 16-lead wide-body SOIC package (SOIC_W) with creepage ≥7.6 mm and air gap ≥8.0 mm, certified for reinforced insulation per IEC 60747-5-2 and UL 1577.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD1 | Primary-side power supply input | Accepts 3.0–5.5 V; powers input-side logic and isoPower oscillator; must be decoupled near Pin 1 |
| GND1 (Pins 2, 8) | Primary-side ground reference | Internally shorted; both pins must connect to same low-impedance ground plane to minimize noise coupling |
| VIA, VIB | Input-side logic signal inputs | CMOS-compatible; VIH = 0.7×VDD1, VIL = 0.3×VDD1; drive internal transformers directly |
| VOA, VOB | Output-side logic signal outputs | Unidirectional outputs (VIA→VOA, VIB→VOB); VOH ≥ VISO − 0.5 V @ 4 mA; VOL ≤ 0.4 V @ 4 mA |
| VISO | Isolated secondary supply output | Regulated 3.3 V or 5.0 V output; supplies output-side logic and external loads up to 100 mA (5 V mode) |
| GNDISO (Pins 9, 15) | Secondary-side ground reference | Internally shorted; separate from GND1; forms isolation barrier return path for VISO and output logic |
| VSEL | Isolated supply voltage select | Tied to VISO → 5.0 V output; tied to GNDISO → 3.3 V output; no function in slave regulation mode |
| RCSEL | Regulation mode control | High → self-regulation; low → slave mode (requires external master regulator); weak internal pull-up |
| VE2 | Output enable | High or floating → outputs active; low → VOA/VOB enter high-Z state - enables power sequencing |
| RCIN | Regulation control input | In slave mode only; connects to RCOUT of master isoPower device; must not be high when RCSEL = low |
| NC (Pins 7, 12) | No internal connection | Not bonded; leave unconnected and unpopulated on PCB; avoid routing traces beneath |
Key Features
| Feature | Design Value |
|---|---|
| Integrated isoPower DC-DC converter | Eliminates need for external isolated power supply; reduces BOM count and board area in space-constrained designs |
| Reinforced insulation certification | UL 1577 (2500 V rms), VDE 0884-2 (VIORM = 560 VPEAK), CSA - enables single-component safety compliance in medical/industrial systems |
| High CMTI (>25 kV/µs) | Prevents data corruption during fast transients from motor drives or inverters - critical for reliable fieldbus communication |
| Configurable isolated output voltage | VSEL pin selects 3.3 V or 5.0 V output without external components - simplifies design reuse across voltage domains |
| Thermal shutdown with hysteresis | Triggers at 150°C (TSSD), resets at 130°C (TSSD-HYS) - protects against sustained overload or poor heatsinking |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel isolated power + signal applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADuM5201CRWZ | Swapped channel directionality: VIA→VOB, VIB→VOA (cross-coupled vs. ADuM5202's direct-coupled VOA/VIB) | Requires PCB layout revision to match signal routing; unsuitable where strict input→output pin alignment is required | Select ADuM5201CRWZ only when cross-channel mapping matches system-level signal flow (e.g., differential pair inversion) |
| Si88220ED-IS | Capacitive isolation; 5000 V rms rating; 100 Mbps data rate; no integrated DC-DC (requires external isolated supply) | Higher isolation voltage but adds external DC-DC complexity; better for ultra-high-speed links where power integration is secondary | Choose Si88220ED-IS when >25 Mbps speed or >2500 V rms isolation is mandatory, and board space allows discrete power solution |
Compared with ADuM5202CRWZ, ADuM5201CRWZ offers identical specs except inverted channel mapping-requiring layout changes-while Si88220ED-IS trades integrated power for higher speed and isolation voltage, increasing BOM and design effort.

FAQ
What is the maximum isolated output current supported by the ADuM5202CRWZ?
The ADuM5202CRWZ delivers up to 100 mA at 5.0 V output (VSEL = VISO) or 60 mA at 3.3 V output (VSEL = GNDISO), as specified in Table 1 and confirmed in Tables 3, 7, and 11 of the Rev. B datasheet. Current capability is derated above 85°C per the thermal derating curve in Figure 5. The ADuM5202CRWZ must not exceed these limits to maintain regulation and avoid thermal shutdown.
Can the ADuM5202CRWZ operate with a 3.3 V primary supply and 5.0 V isolated output?
No. The ADuM5202CRWZ does not support 3.3 V input with 5.0 V isolated output. Per Tables 1, 6, and 10, valid configurations are: (1) 5.0 V VDD1 → 5.0 V VISO, (2) 5.0 V VDD1 → 3.3 V VISO, or (3) 3.3 V VDD1 → 3.3 V VISO. Attempting 3.3 V VDD1 with VSEL = VISO violates the minimum VDD1 requirement of 4.5 V for 5.0 V VISO mode and will cause undervoltage lockout.
How does the RCSEL pin affect ADuM5202CRWZ operation?
When RCSEL is high, the ADuM5202CRWZ operates in self-regulation mode and controls its own VISO output. When RCSEL is low, it enters slave mode and requires an external master isoPower device (e.g., ADuM5020) to regulate VISO via the RCIN pin. The ADuM5202CRWZ datasheet explicitly warns that tying RCIN high while RCSEL is low causes overvoltage damage - a critical constraint in system-level power architecture design.
What is the purpose of the VE2 pin on the ADuM5202CRWZ?
The VE2 pin enables output-state control: when high or floating, VOA and VOB drive actively; when low, both outputs enter high-impedance (high-Z) state. This allows safe power sequencing - for example, holding outputs inactive until VISO reaches regulation - and supports hot-swap or fault-isolation scenarios. Unlike enable pins on many isolators, VE2 affects only the output drivers, not the internal isoPower or input receivers.
Does the ADuM5202CRWZ require external filtering components on the VISO output?
Yes. The ADuM5202CRWZ requires a minimum 0.1 µF ceramic capacitor in parallel with a 10 µF bulk capacitor (e.g., tantalum or aluminum electrolytic) at the VISO pin, as specified in Tables 2, 6, and 10 for ripple/noise testing. Omitting this filter increases output ripple beyond 75 mVp-p (5 V mode) and risks violating noise-sensitive downstream logic thresholds. Layout must minimize loop inductance with short, wide traces to both capacitors.
