SI8660EC-AS1

Digital Isolators Overview

The SI8660EC-AS1 is a six-channel digital isolator from Skyworks Solutions, designed for automotive applications. It features capacitive coupling isolation with a rated insulation voltage of 3750 Vrms. The device supports unidirectional signal transmission at data rates up to 150 Mb/s. Key electrical parameters include a propagation delay of 8 ns and a pulse width of 5 ns. It operates on a supply voltage range of 2.5 V to 5.5 V with a typical quiescent current of 8.8 mA. The component is housed in a 16-pin SOIC package and functions within a temperature range of -40°C to +125°C.

Digital Isolators Feature Summary

• Provides high-voltage galvanic isolation between circuits using capacitive coupling technology.
• Supports high-speed data transmission with low propagation delay for precise timing control.
• Engineered for automotive environments with extended operating temperature capabilities.

Digital Isolators Applications

• Automotive powertrain control systems
• Inverter gate drive isolation
• Battery management system communication interfaces

Digital Isolators Procurement Notes

Verify the specific suffix 'AS1' against the manufacturer's official datasheet to confirm the tube packaging configuration. Ensure that the AEC-Q100 qualification status aligns with project requirements. Cross-reference the pinout diagram with the target PCB footprint to prevent installation errors during assembly.

Digital Isolators Selection Notes

Select this component when six independent unidirectional channels are required for high-voltage isolation. Consider the 3750 Vrms insulation rating for safety compliance. Evaluate the 8.8 mA power consumption against thermal constraints. Compare against other Si866x variants if bidirectional signaling or different channel counts are needed.

Digital Isolators Part Context

This part belongs to the Si866x family of ultra-low-power digital isolators. It shares the same core architecture as other models in the series but differs in insulation voltage ratings and channel configurations. The EC designation typically indicates specific automotive-grade reliability standards compared to commercial variants.

Digital Isolators Replacement Considerations

SI8660ED-ASR offers similar functionality with a higher 5 kVrms insulation rating. SI8661BC-AS1 provides mixed polarity options with five forward and one reverse channel. Verify pin compatibility and insulation requirements before substituting.
