STUSBCD01BJR

Specialized Overview

The STUSBCD01BJR is a USB charger detection interface integrated circuit manufactured by STMicroelectronics. It identifies dedicated USB chargers, Host/Hub chargers, or standard host ports connected to the USB DP/DM data lines. The device operates with a VBAT supply voltage ranging from 2.2 V to 4.5 V and supports an interface voltage range of 1.6 V to 2.8 V (VIO). It features low DP-DM input capacitance and includes a VBUS voltage clamping circuit that prevents voltages from exceeding 6 V typical. The component functions within an ambient temperature range of -40°C to +85°C and consumes 5 uA during operation. It is housed in a Flip-Chip-12 package.

Specialized Feature Summary

• Implements dual detection methods to distinguish between dedicated chargers and Host/Hub chargers using current sink and dedicated techniques.
• Provides an active high open drain hardware detection output pin for direct status signaling.
• Integrates an internal regulator to supply 1.8 V to internal blocks and state machines while protecting against overvoltage.

Specialized Applications

• Detecting dedicated USB chargers in mobile devices
• Identifying Host/Hub chargers in portable electronics
• Differentiating standard host ports in consumer appliances

Specialized Procurement Notes

Verify the specific suffix 'JR' against the manufacturer's official documentation to confirm package type and reel specifications. Ensure compatibility with the required operating temperature range and voltage levels before integration. Cross-reference the RoHS compliance status with the latest environmental declarations provided by the supplier.

Specialized Selection Notes

Select this component when distinguishing between dedicated and host chargers via DP/DM lines is required. Ensure the system design accommodates the 2.2 V to 4.5 V supply range and the 1.6 V to 2.8 V I/O voltage. Verify that the Flip-Chip-12 package fits the PCB layout constraints and thermal requirements.
