RTKA489110DE0000BU
The
RAA489110
is a configurable buck-boost Narrow
Output Voltage DC (NVDC) and Hybrid Power
Buck-Boost (HPBB/Bypass) combo charger that uses
the advanced Renesas R3™ Technology to provide
high light-load efficiency, fast transient response, and
seamless DCM/CCM transitions for a variety of
mobile and industrial applications.
In Charge mode, the RAA489110 takes input power
from a wide range (4V to 30V) of DC power sources
(such as conventional AC/DC charger adapters, USB
PD ports, travel adapters) and safely charges battery
packs with up to four cells in a series configuration.
The RAA489110 supports On-the-Go (OTG)
functionality from 2-cell and 4-cell battery
applications. When OTG function is enabled, the
RAA489110 operates in Reverse Buck mode to
provide 5V at the USB port.
Serial communication through SMBus/I
programming of many critical parameters to deliver a
customized solution. These programming parameters
include, but are not limited to, adapter current limit,
charger current limit, system voltage setting, and
trickle charging current limit.
The RTKA489110DE0000BU evaluation board
demonstrates the performance of the RAA489110.
From the PROG pin to GND, a 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.

    Pin # Pin Name Layout Guidelines Connect this ground pad to the ground plane through a low impedance path. Renesas recommends Bottom using at least five vias to connect to ground planes in the PCB to ensure sufficient thermal dissipation directly under the IC.
  • Page 15 PHASE1 Run these two traces in parallel fashion with sufficient width. Avoid any sensitive analog signal trace from crossing over or getting close. Renesas recommends routing the PHASE1 trace to the high-side MOSFET drain pin instead of general copper. Place the IC close to the switching MOSFETs gate terminals and keep the gate drive signal traces short for a clean MOSFET drive.
