STCC5021IQTR

Overview

The STCC5021IQTR is a USB charging controller IC designed for attach detection and power management in portable devices. It supports USB 2.0 SDP and CDP data pass-through with S3 remote wakeup, as well as permanent USB 3.0 SuperSpeed data pass-through. The device handles DCP modes including BC1.2, divider, and auto-detect, providing charging indication after negotiation. It features attach and charging/end-of-charging detection, along with resistor-programmable precise current limiting and short-circuit protection.

Feature Summary

Supports USB 2.0 SDP and CDP data pass-through with S3 remote wakeup or automatic charging capabilities
Enables permanent USB 3.0 SuperSpeed data pass-through between input and output connectors
Provides DCP mode operation with charging indication for BC1.2, divider, and auto-detect configurations
Includes attach and charging/end-of-charging detection with resistor-programmable current limiting

Applications

Evaluation of STCC5021 parameters and operating modes using STEVAL-ISB018V1 board
USB charging controller implementation in portable electronic devices
Systems requiring USB 3.0 SuperSpeed data pass-through with charging detection

Procurement Notes

Verify the specific suffix IQTR against official STMicroelectronics documentation to confirm package type, temperature range, and tape-and-reel specifications. Confirm NRND status if applicable, as this may impact long-term availability. Ensure compatibility with required USB standards and voltage levels before procurement.

Selection Notes

Select this component when USB 3.0 SuperSpeed data integrity must be maintained alongside charging detection functions. It is suitable for designs requiring programmable current limiting and support for multiple DCP modes including BC1.2. Evaluate thermal performance and interface requirements against the specific application constraints.

Part Context

The STCC5021 belongs to STMicroelectronics' family of USB charging controllers. It is often evaluated using dedicated boards like the STEVAL-ISB018V1 to verify functionality across various USB charging protocols and data transmission modes.
