ISL88694IH5-TK

Overview

The ISL88694IH5-TK is a high-performance SMBus Accelerator (SMA) manufactured by Renesas Electronics, originally developed under the Intersil brand. This component integrates an SMBus interface with advanced power management capabilities, designed to simplify system control and monitoring in complex electronic architectures. It features a compact HTSSOP-20 package, ensuring efficient space utilization on printed circuit boards. The device supports standard SMBus protocols for communication, enabling seamless integration with host controllers for real-time data exchange and configuration management in industrial and computing applications.

Feature Summary

• Integrates SMBus interface functionality for streamlined system communication
• Provides advanced power management acceleration capabilities
• Utilizes compact HTSSOP-20 packaging for dense board layouts

Applications

• Industrial control systems requiring SMBus monitoring
• Server and workstation power management interfaces
• Embedded computing platforms needing accelerated SMBus transactions

Procurement Notes

Verify the manufacturer designation as Renesas Electronics Corporation, as Intersil operations were acquired. Confirm the specific suffix TK indicates tape and reel packaging if required for automated assembly. Check current product status, as legacy components may have end-of-life notifications or replacement recommendations from the manufacturer. Ensure compatibility with existing SMBus voltage levels and protocol requirements before procurement.

Selection Notes

Select this component when an integrated SMBus accelerator is needed to reduce host processor load. Verify that the HTSSOP-20 package fits the available footprint. Compare performance against standalone SMBus controllers if additional I/O expansion is required. Ensure the operating temperature range meets the specific application environment constraints.

Part Context

This part belongs to the ISL88694 family of SMBus accelerators. The IH5 suffix typically denotes the package type and temperature grade, while TK specifies the tape and reel shipping format. These devices are designed to offload SMBus tasks from main processors, improving system efficiency and response times in multi-device environments.

Replacement Considerations

Check for direct pin-to-pin replacements within the Renesas portfolio. Verify if newer revisions of the ISL88694 series offer improved features or updated packaging options. Consult manufacturer documentation for any recommended upgrades or alternative components with similar SMBus acceleration capabilities.
