Product details

Overview

SI86S600AE-IS4R from Skyworks Solutions is a bidirectional I²C isolator with two independent galvanically isolated I²C channels (SDA and SCL), rated for 5.0 kV_RMS isolation, operating from 3.0–5.5 V supply, supporting up to 1.7 MHz I²C bus speed, and featuring open-drain outputs with 35 mA sink capability - deployed in isolated battery management systems and PoE-powered controllers.

For engineers reviewing the SI86S600AE-IS4R datasheet, SI86S600AE-IS4R pinout, SI86S600AE-IS4R application, or SI86S600AE-IS4R equivalent, this page delivers verified electrical specs, automotive-grade AEC-Q100 qualification status, SOIC-16 wide-body package mapping, anti-latch I²C operation details, and real-world design constraints for ground-loop-free serial communication in high-reliability industrial and automotive subsystems.

Technical Context

The SI86S600AE-IS4R implements RF-based semiconductor isolation with on/off keying modulation across a robust dielectric barrier, enabling bidirectional SDA/SCL signal transfer without external anti-latch circuitry. Its side-A logic levels (V_OL = 0.54–0.8 V, V_IL = 0.41 V min) are engineered to prevent bus latching by maintaining ≥50 mV margin between output low and input threshold.

It features independent undervoltage lockout (UVLO) per side (AVDD/BVDD), hot-swap protection during live insertion, and supports I²C clock stretching. The device operates across –40 °C to +125 °C and meets reinforced insulation requirements per IEC 60950-1, UL 1577, and VDE 0884-10.

Key Features

Feature	Design Value
Bidirectional I²C channel pair	Single-chip SDA+SCL isolation eliminates need for dual unidirectional isolators and external latch prevention logic.

Equivalent & Alternatives

The following parts are listed as comparable options for similar bidirectional I²C isolation applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
ADUM1250ARZ	2.5 kV_RMS isolation rating; 1 Mbps max I²C speed; CMOS input thresholds; no side-A anti-latch optimization.	Suitable for non-automotive, lower-voltage (<250 V) industrial I²C links where full 5.0 kV_RMS and 1.7 MHz are not required.	Select ADUM1250ARZ only if system-level safety certification allows reduced isolation and timing margins.
ISO1540DR	3.75 kV_RMS isolation; 1 MHz max I²C speed; requires external pull-ups on both sides; no AEC-Q100 qualification.	Fits cost-sensitive consumer or white-goods applications with moderate noise immunity needs and no automotive qualification mandate.	Choose ISO1540DR when automotive traceability, extended temperature range, or 1.7 MHz operation is unnecessary.

Compared with ADUM1250ARZ and ISO1540DR, SI86S600AE-IS4R delivers higher isolation (5.0 kV_RMS), faster timing (1.7 MHz), built-in anti-latch behavior, and full AEC-Q100 qualification - making it the only option qualified for functional safety–relevant battery monitoring and traction inverter subsystems.

FAQ

What is the isolation voltage rating of SI86S600AE-IS4R and which safety standards does it meet?

SI86S600AE-IS4R is rated for 5.0 kV_RMS isolation per UL 1577 and certified to reinforced insulation standards including IEC 60950-1, IEC 60601-1, and VDE 0884-10. It meets creepage and clearance requirements for 8.3 mm minimum spacing in wide-body SOIC packaging, enabling use in medical and automotive high-voltage subsystems where reinforced insulation is mandated.

Does SI86S600AE-IS4R support I²C clock stretching, and how is it implemented?

Yes, SI86S600AE-IS4R fully supports I²C clock stretching on both SDA and SCL lines. Its bidirectional architecture preserves the open-drain nature and timing semantics of native I²C, allowing slave devices to hold SCL low without disrupting arbitration or causing bus lockup - confirmed by design validation in Figures 4.2–4.6 of the Si860x datasheet.

What is the purpose of the side-A anti-latch feature in SI86S600AE-IS4R?

The side-A anti-latch feature in SI86S600AE-IS4R ensures that V_OL(A) (output low voltage) remains ≥50 mV above V_IL(A) (input low threshold), preventing positive feedback that would otherwise latch the I²C bus in a permanent low state. This eliminates the need for external circuitry and is validated per Table 3.1 and Figure 3.1 in the Si860x datasheet.

Can SI86S600AE-IS4R operate with different supply voltages on each side (e.g., 3.3 V on Side A and 5 V on Side B)?

Yes, SI86S600AE-IS4R supports independent supply domains: AVDD and BVDD each operate from 3.0 V to 5.5 V, enabling mixed-voltage I²C interfacing - for example, connecting a 3.3 V microcontroller (Side A) to a 5 V isolated sensor node (Side B) without external level shifters, as specified in Table 5.1 and Section 4.2 of the datasheet.

Is SI86S600AE-IS4R qualified for automotive applications, and what documentation is available?

Yes, SI86S600AE-IS4R is an automotive-grade part (denoted by "-A" suffix), qualified to AEC-Q100 Rev G, with AIAG-compliant PPAP documentation, IMDS and CAMDS material declarations, and zero-defect manufacturing controls - all explicitly stated in Table 1.1 and Section 1 of the Si860x datasheet.
