The RTQ7882 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 features an embedded ARM Cortex-M0 MCU, which handles various functions such as communication protocol, smart control of the PWM converter, firmware-based protections, and customized functions. The IC also 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 overcurrent protection, so that the protections have faster responses and can still function even when the MCU is not activated. The RTQ7882 provides an excellent USB PD solution for USB-PD provider applications with minimal external components and a simple PCB layout.The recommended junction temperature range is -40°C to 125°C, and the ambient temperature range is -40°C to 105°C.
