AAT3517IGV-2.93-C-C-T1

Overview

The AAT3517IGV-2.93-C-C-T1 is a micropower supervisor IC manufactured by Skyworks Solutions Inc., designed for simple reset and power-on reset functions. It features a fixed voltage threshold of 2.93V, ensuring precise monitoring of supply rails in low-power applications. The device operates within an ambient temperature range of -40°C to +85°C, providing reliable performance across standard industrial conditions. Packaged in a compact SOT-23-5 form factor, it supports surface-mount assembly via tape and reel. This component is classified under PMIC supervisors and is currently marked as obsolete with no further manufacturing.

Feature Summary

• Provides simple reset and power-on reset functionality
• Features a fixed 2.93V voltage threshold for accurate supervision
• Designed for micropower applications to minimize energy consumption

Applications

• Portable electronic devices requiring low standby current
• Battery-powered systems needing reliable power-on reset

Procurement Notes

This component is officially listed as obsolete and is no longer manufactured by Skyworks Solutions Inc. Procurement should focus on verifying the authenticity of existing stock from authorized distributors or secondary market suppliers. Buyers must confirm the part status explicitly, as availability is limited to remaining inventory. Cross-referencing with substitute components like the TPS3820-33DBVR is recommended for new designs to ensure long-term supply chain stability.

Selection Notes

Engineers selecting this part should note its obsolete status, which may impact future production scalability. The fixed 2.93V threshold suits applications where this specific voltage level aligns with system requirements. Due to discontinuation, alternative solutions with similar pinouts and reset functionalities should be evaluated. Designers must verify that the SOT-23-5 package dimensions match their PCB layout constraints before finalizing any legacy board revisions.

Part Context

The AAT3517 series belongs to Skyworks' portfolio of power management integrated circuits, specifically categorized under PMIC supervisors. These components are engineered to monitor voltage levels and generate reset signals for digital logic. The IGV suffix indicates the specific package type and thermal characteristics, while the C-C-T1 designation refers to the commercial temperature grade and tape-and-reel packaging format used for automated assembly processes.

Replacement Considerations

The TPS3820-33DBVR from Texas Instruments is identified as a similar available substitute. Engineers should evaluate electrical compatibility, including threshold voltage differences and package pinout alignment, before implementing this replacement in existing designs.
