George Hariman Principal Engineer George Hariman is currently a Systems Architect at ROHM Semiconductor, where he works to design-in the company’s broad portfolio of analog and power products into end-customer applications. His previous power-management and power-electronics experience includes design of integrated circuits for point-of-load voltage regulators, LED drivers for display, lighting and camera flash products, and other power-management circuits. He holds a Bachelor of Science in Electrical and Computer Engineering from the University of California, San Diego, and a Master of Science in Electrical Engineering from Stanford University.

ROHM Stand-alone USB-PD Solutions: BD93F10MWV, BD93E11GWL, & BD91N01NUX

In partnership with ROHM Semiconductor

In this presentation, we will review ICs that are members of ROHM’s proven full-feature USB Type-C Power Delivery (PD) controller portfolio. They provide for quick and easy design and implementation of USB Type-C PD for sink applications (UFP). Supporting the full suite of UFP features, they are verified as compliant, and do not need an external MCU. They handle all functions required by UFP, including dead battery, plug-in, and detach detection. The devices provide control of the required power path NMOS FETs which provide power isolation and reverse current protection. The voltage range and sink power settings are selectable by GPIOs. Applications and products that require a USB-PD interface for charging can readily use these ICs without the need for any firmware development, making them ready for compliance testing.
