RT1730WSC

Overview

The RT1730WSC is a programmable USB Type-C Power Delivery controller manufactured by Richtek USA Inc. It operates within a supply voltage range of 2.7 V to 5.5 V and supports low-speed communication at 300 kb/s. The component utilizes an I²C interface for configuration and control. It is housed in a compact 9-WLCSP package with dimensions of 1.38x1.34 mm, designed for surface mount installation. The device functions reliably across an operating temperature range of -40°C to +85°C.

Feature Summary

• Supports USB Type-C Power Delivery standards for programmable power negotiation
• Utilizes I²C interface for system integration and control
• Compact 9-WLCSP package design suitable for space-constrained applications

Applications

• USB Type-C port controllers
• Power delivery adapters
• Portable electronic devices requiring USB-C connectivity

Procurement Notes

Verify the specific datasheet version and RoHS compliance status directly with Richtek or authorized distributors before procurement. Ensure that the 9-WLCSP footprint matches the target PCB layout constraints. Confirm that the I²C address settings align with the host system requirements to prevent bus conflicts during implementation.

Selection Notes

Select this component when a small form factor USB-C PD controller is required. The 9-WLCSP package offers significant size reduction compared to larger BGA or QFN options. Consider the 2.7 V minimum supply voltage for compatibility with single-cell battery systems. Verify thermal performance within the specified -40°C to +85°C range for the intended environment.

Part Context

The RT1730WSC belongs to Richtek's specialized interface integrated circuit portfolio focused on USB Type-C technology. It complements other models in the series by providing dedicated power delivery control capabilities. The component is part of the broader ecosystem of USB interface solutions designed to facilitate modern charging and data transfer protocols in consumer electronics.

Replacement Considerations

Consult official substitution lists from Richtek for verified alternatives. Cross-reference pinout compatibility and electrical specifications if considering similar packages from other manufacturers. Ensure any substitute maintains support for USB Type-C PD standards and I²C communication interfaces.
