Analog Devices Inc. ADUM6210BRSZ

Overview

ADuM6210BRSZ from Analog Devices is a dual-channel digital isolator with integrated isoPower® DC-to-DC converter, providing galvanic isolation and regulated 3.3 V or 5.0 V isolated supply up to 150 mW. It delivers two unidirectional signal channels (A and B), supports data rates up to 100 Mbps (NRZ), and operates across −40°C to +105°C in industrial PLCs and isolated sensor interfaces.

For engineers reviewing the ADuM6210BRSZ datasheet, ADuM6210BRSZ pinout, ADuM6210BRSZ application, or ADuM6210BRSZ equivalent, key selection criteria include its 20-lead SSOP package with 5.3 mm creepage, reinforced 3750 V_rms isolation rating, VIORM = 849 V_peak, and high common-mode transient immunity (>25 kV/µs).

Technical Context

The ADuM6210BRSZ uses iCoupler® chip-scale transformer technology for both signal isolation and power transfer, eliminating external isolated DC-DC converters. Its isoPower section employs high-frequency switching (125 MHz oscillator, 600 kHz PWM) with soft-start and thermal shutdown at 154°C.

Signal channels feature independent input/output supplies (VDD1/VDD2), programmable VISO via VSEL resistor network, and undervoltage lockout (2.65 V/2.75 V thresholds). Pin assignments are fixed: VIA/VIB inputs on Side 1; VOA/VOB outputs on Side 2 - confirming unidirectional A→A, B→B topology.

Key Specifications

Pinout & Package

ADuM6210BRSZ is housed in a 20-lead SSOP package (7.2 mm × 7.8 mm, 0.65 mm pitch) with input-side (P-side) and output-side (ISO-side) pins physically segregated to maximize creepage and minimize coupling.

Compared with ADuM6210BRSZ, ADuM6211BRSZ reassigns channel directionality - requiring PCB layout changes - while Si88220ED-IS trades programmable VISO and 150 mW power for higher isolation rating and capacitive robustness, making it suitable only where those specific trade-offs align with system constraints.

FAQ

What is the maximum output power capability of the ADuM6210BRSZ's integrated DC-DC converter?

The ADuM6210BRSZ delivers up to 150 mW of isolated output power when configured for 5 V input and 5 V output. At 3.3 V output, maximum power drops to 100 mW (5 V_IN) or 66 mW (3.3 V_IN). This is specified in Table 2 of the datasheet and verified across temperature (−40°C to +105°C) with load regulation ≤3%. The ADuM6210BRSZ must be derated above 85°C ambient per Figure 2 thermal curve.

Can the ADuM6210BRSZ support bidirectional communication protocols like I²C?

No - the ADuM6210BRSZ implements two unidirectional channels (VIA→VOA, VIB→VOB) and cannot natively support true bidirectional protocols. For I²C isolation, Analog Devices recommends the ADuM1250 or ADuM2250, which feature dedicated open-drain outputs and bus arbitration logic. Using ADuM6210BRSZ for I²C requires external pull-up resistors and careful timing analysis due to fixed directionality.

What safety certifications does the ADuM6210BRSZ hold, and what do they cover?

The ADuM6210BRSZ is UL recognized (File E214100), CSA approved (File 205078), and VDE certified (File 2471900-4880-0001) to DIN V VDE V 0884-10:2006-12. These cover reinforced insulation with 3750 V_rms withstand voltage, VIORM = 849 V_peak, and 5.3 mm creepage - validating its use in industrial equipment requiring basic or reinforced isolation per IEC 61800-5-1 and IEC 61000-4-5.

How is the isolated output voltage (VISO) programmed on the ADuM6210BRSZ?

VISO is set using an external resistor divider between VISO and GNDISO connected to the VSEL pin. For 3.3 V output, R1 = 10 kΩ and R2 = 16.9 kΩ yield 1.25 V at VSEL; for 5.0 V, R1 = 10 kΩ and R2 = 30.9 kΩ are used. The ADuM6210BRSZ's internal reference compares VSEL to 1.25 V, regulating VISO accordingly - detailed in Tables 7 and 11 of the datasheet.

Does the ADuM6210BRSZ require external bypass capacitors, and if so, where?

Yes - the ADuM6210BRSZ requires 0.1 µF || 10 µF ceramic capacitors between VISO and GNDISO (CBO), plus 0.1 µF capacitors on VDD1, VDD2, and VDDP relative to their respective grounds. These suppress high-frequency switching noise from the isoPower converter and ensure stable logic operation. Layout guidelines are specified in AN-0971 and Section 20 of the datasheet.
