Renesas RTKA489000DE0000BU Manual

RTKA489000DE0000BU
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 port (OTG mode)
from 2- to 4-cell batteries that allow configurations to
support USB PD output for Programmable Power
Supply (PPS) ports. Because of the on-chip TCPC
and Renesas advanced R3™ Technology,
RAA489000 is fully compliant with USB PD Sink Fast
Role Swap (FRS) specification by monitoring CC line
and bringing VBUS voltage back to a safe range
rapidly. The RAA489000 has dual SMBus/I
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#.
The RTKA489000DE0000BU evaluation board is
designed to demonstrate the performance of the
RAA489000. From the PROG pin to GND, the resistor
can be used to program the default value numbers of
the battery in series, the switching frequency, and the
adapter current limit charging function. The default
value numbers can also be set by SMBus.
