The RAA489000 is a digitally configurable buck-boost battery charger with USB-C® Port Controller (TCPC). The battery charging function supports Narrow Voltage Direct Charging (NVDC) and USB Power Delivery (PD) programmable power supply output supplies. The TCPC controller integrates TCPC PHY, CC-Logic, and VCONN switches. All RAA489000 blocks connected to the adapter/USB pin (CC1, CC2, VBUS) are protected from input overvoltage events up to 28V. The back-to-back NFET driver and VBUS self-discharge control further simplify the USB PD designs. The RAA489000 supports reverse buck, boost, or buck-boost operation to the adapter/USB port from 2- to 4-cell batteries to allow configurations to support USB PD output for Programmable Power Supply (PPS) ports. Thanks to the on-chip TCPC and Renesas advanced R3™ Technology, RAA489000 is fully compliant with USB PD Sink Fast Role Swap (FRS) spec by monitoring CC line and bringing VBUS voltage back to a safe range rapidly.

The RAA489000 has dual SMBus/I2C ports supporting simultaneous direct charger function programming and CC line traffic through TCPCI when operating with a USB-C Port Manager (TCPM) such as the Renesas R9A02G015 to form a complete USB PD compliant solution for single-port or multi-port applications. The RAA489000 battery charger supports all NFETs solution and supports system power from the adapter, battery, or a combination of both. The on-chip ADC monitors the charging input voltage/current, battery voltage, charging/discharging current, and the battery temperature. For Intel™ IMVP compliant systems, the RAA489000 includes PROCHOT#.
