General Description
The RT7882 is a USB Type-C Power Delivery (USBC
PD) and PWM buck-boost controller with highly
integrated functions and flexibility for USB PD provider
applications. The IC has an embedded ARM CortexTMM0
MCU, which handles various functions of
communication protocol, smart control of the PWM
converter, firmware-based protections, and customized
functions. The IC features hardware-based protections,
such as inductor peak current limit, VBUS overvoltage
protection (VBUS OVP), VIN undervoltage protection
(VIN UVP), VIN overvoltage protection (VIN OVP), VO
undervoltage protection (VO UVP), and VCONN
current-limit protection, so that the protections have
faster responses and can still function even when the
MCU is not activated. The RT7882 can offer an
excellent USB PD solution for a USB-PD Provider
application with few external components and simple
PCB layout.
