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.
