Overview

ADUM6410BRSZ from Analog Devices is a quad-channel digital isolator with integrated isoPower® DC-to-DC converter, providing 150 Mbps signal isolation and up to 150 mW isolated output power at 5 V/5 V operation. It features 24-lead SSOP packaging with 5.3 mm creepage, 100 kV/µs common-mode transient immunity, and reinforced insulation rated at 3750 V_rms for 1 minute - deployed in industrial PLCs and isolated sensor interfaces.

For engineers reviewing the ADUM6410BRSZ datasheet, ADUM6410BRSZ pinout, ADUM6410BRSZ application, or ADUM6410BRSZ equivalent, this page delivers verified specifications including VISO setpoint (4.7–5.4 V), propagation delay (4.8–13 ns), pulse width distortion (0.5–3 ns), thermal shutdown (154°C), and regulatory compliance per UL 1577, IEC/CSA 62368-1, and DIN EN IEC 60747-17.

Technical Context

The ADUM6410BRSZ implements iCoupler® chip-scale transformer technology for both data channel isolation and magnetic DC-DC conversion, eliminating external isolated power supplies. Its four independent unidirectional channels (I/O1A–I/O1D input-side, I/O2A–I/O2D output-side) support configurable voltage combinations: 5 V/5 V (150 mW), 5 V/3.3 V (100 mW), or 3.3 V/3.3 V (66 mW).

It integrates undervoltage lockout (1.5–1.6 V thresholds), adjustable VISO via external resistor network (R1 = 10 kΩ, R2 = 30.9 kΩ for 5 V output), and operates across −40°C to +105°C. The device uses PWM-controlled 600 kHz switching with 125 MHz oscillator frequency and supports 1.8 V to 5.5 V logic on both sides.

FAQ

What is the maximum output power of ADUM6410BRSZ at 5 V secondary supply?

The ADUM6410BRSZ delivers up to 150 mW of isolated output power when configured for 5 V secondary supply (VISO = 5 V) with 5 V primary input. This is confirmed in Table 1 of the datasheet Rev. B and supports powering small isolated loads such as ADC references or gate driver bias rails without external DC-DC converters. The ADUM6410BRSZ achieves this using its integrated isoPower® magnetic DC-DC converter.

Does ADUM6410BRSZ support bidirectional data channels?

No, ADUM6410BRSZ provides four unidirectional channels: I/O1A–I/O1D are inputs on the primary side (VDD1), and I/O2A–I/O2D are outputs on the isolated secondary side (VDD2). This fixed directionality is defined in Table 2 of the datasheet and distinguishes it from variants like ADUM6411BRSZ. The ADUM6410BRSZ is optimized for applications such as sensor-to-PLC data acquisition where signal flow is strictly one-way.

What safety certifications apply to ADUM6410BRSZ?

ADUM6410BRSZ is certified to UL 1577 (3750 V_rms/1 min), IEC/CSA 62368-1, IEC/CSA 60601-1 (1 MOPP), IEC/CSA 61010-1, and DIN EN IEC 60747-17 (VDE 0884-17). These approvals confirm reinforced insulation and suitability for medical, industrial, and test equipment. All certifications are listed in Table 22 of the ADUM6410BRSZ datasheet Rev. B.

Can ADUM6410BRSZ operate with 1.8 V logic on both sides?

Yes, ADUM6410BRSZ supports 1.8 V operation on both VDD1 and VDD2 sides, as verified in Table 18 and Table 19 of the datasheet Rev. B. At 1.8 V, it maintains 150 Mbps data rate, 5.8–15 ns propagation delay, and 470 ps p-p jitter. However, the integrated DC-DC converter requires ≥3.0 V input; thus, VDD1 = 1.8 V operation disables VISO generation - the part functions as a pure digital isolator in that mode.

What is the thermal shutdown threshold for ADUM6410BRSZ?

The ADUM6410BRSZ activates thermal shutdown at 154°C, with 10°C hysteresis, as specified in Tables 3, 7, and 11 of the datasheet Rev. B. This protects the device during sustained overload or poor PCB thermal design. Recovery occurs at ~144°C. The junction-to-ambient thermal resistance (θ_JA) is 50°C/W on a 4-layer board - critical for thermal layout validation when delivering 150 mW output power.
