RTKA489118DE0000BU, RTKA489118DE0010BU
The RTKA489118DE0000BU and
RTKA489118DE0010BU evaluation boards evaluate
the performance of the RAA489118. The default value
numbers of maximum and minimum output voltages,
autonomous charging mode, and the adapter current
limit charging function can be programmed by the
resistor from the PROG pin to GND. The values can
also be set by SMBus.
The
RAA489118
is a buck-boost charger supporting
30V input and 30V battery. The RAA489118 provides
charging and protection features for power tools,
portable vacuums, battery-powered lawn mowers,
power banks, and additional system bus regulation for
notebooks. It also supports any USB-C interface
platform including USB PD EPR. The advanced
Renesas R3™ technology provides highly efficient
light-load operation and fast transient response.
In Charging mode, the RAA489118 accepts input
power from a wide range of DC power sources (such
as conventional AC/DC charger adapters, USB PD
ports, and travel adapters) and safely charges battery
packs with up to 7 serially connected battery cells up
to 30V. The device can operate with only a battery,
only an adapter, or with both connected.
The RAA489118 supports reverse buck, reverse
boost, or reverse buck-boost operation to the input
port from 2-cell to 7-cell batteries.
The RAA489118 provides programming resistor
options including autonomous charging, max output
voltages, adapter current limit. Additionally, it provides
serial communication that enables programming of
many critical parameters to deliver a customized
solution.
