Overview
The STCC2540IQTR is a USB charger controller integrating a wide bandwidth data switch and a high current power switch in a single package. It emulates profiles compatible with USB Battery Charging Specification BC1.2, Chinese telecommunications standard YD/T 1591-2009, and proprietary modes. The device features an integrated VBUS power switch with low RON of 65 mΩ, adjustable current limit up to 2.8 A, and supports remote wakeup in S3 states. It operates within a temperature range of -40°C to 85°C and is housed in a VFQFPN 16L 3 x 3 x 0.8 mm package with an exposed pad.
Feature Summary
- Integrates USB charger controller, wide bandwidth data switch, and high current power switch
- Compliant with USB charging specifications BC1.2, USB 2.0, and USB 3.0 standards
- Supports remote wakeup in S3 states and charging indication output in DCP and CDP modes
- Includes constant current mode overcurrent protection, soft-start, and short-circuit protection
Applications
- Industrial applications requiring USB charging control
- Host systems needing battery consumption reduction in S4/S5 states
- Devices supporting USB 2.0 and USB 3.0 data pass-through with charging functionality
Procurement Notes
Verify the specific suffix IQTR against official STMicroelectronics documentation to confirm packaging details and reel specifications. Ensure compatibility with required USB charging standards such as BC1.2 or YD/T 1591-2009 for your design. Confirm thermal management requirements for the VFQFPN package in your application environment.
Selection Notes
Select this component when a unified solution for USB charging negotiation, data switching, and power delivery is required. It is suitable for designs prioritizing space efficiency through integration. Consider its compliance with specific regional standards like YD/T 1591-2009 if targeting those markets. Evaluate the need for S3 remote wakeup support in your system architecture.
Part Context
The STCC2540 belongs to STMicroelectronics' portfolio of USB interface and power management solutions. It addresses the need for compact, compliant USB charging controllers that also manage data connectivity. This part integrates functions typically handled by separate components, simplifying PCB layout and reducing bill of materials for modern electronic devices.
Replacement Considerations
Consult official STMicroelectronics resources for verified substitute part numbers. Ensure any replacement maintains compatibility with BC1.2, USB 2.0/3.0, and YD/T 1591-2009 standards. Verify pinout and package dimensions match the VFQFPN 16L form factor.
