RAA489108

Buck-Boost Narrow VDC Battery Charger with SMBus Interface Supporting USB PD EPR

The RAA489108 is a buck-boost Narrow Output

Voltage DC (NVDC) charger. The RAA489108

Features

▪ Buck-boost NVDC charger for 2, 3, or 4-cell Li-ion

provides NVDC charging, system bus regulation, and

protection features for tablets, Ultrabooks, notebooks,

power banks, and any USB-C interface platform. The

advanced Renesas R3™ technology provides high

light-load efficiency and fast transient response.

batteries

▪ Input voltage range: 3.9V to 30V (no dead zone)

▪ System output voltage: 2.4V to 18.304V

▪ Autonomous charging option (automatic

completion of charging)

In Charging mode, the RAA489108 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 4-series cell Li-ion batteries.

▪ Pass-Through mode in forward direction

▪ System power monitor PSYS output, IMVP

compliant

▪ Up to 1MHz switching frequency

As an NVDC topology charger, the RAA489108 also

regulates the system output to a narrow DC range for

stable system bus voltage. System power can be

provided from the adapter, battery, or a combination

of both. The RAA489108 can operate with only a

battery, only an adapter, or with both connected. For

Intel IMVP8 compliant systems, the RAA489108

includes PSYS (system power monitor) functionality,

which provides an analog signal representing total

platform power consumption. The PSYS output

connects to a wide range of Renesas IMVP8 core

regulators to provide an IMVP8 compliant power

domain function.

▪ Adapter current and battery current monitor

(AMON/BMON)

▪ PROCHOT# open-drain output, IMVP compliant

▪ Trickle charging of depleted battery

▪ Ideal diode control in Turbo mode

▪ Reverse buck, boost, and buck-boost operation

from battery

▪ Two-level adapter current limit available

▪ Battery Ship mode option

▪ SMBus and auto-increment I C compatible

▪ 4×4 32 Ld TQFN package compatible with the

ISL9238 family of parts

The RAA489108 supports reverse buck, reverse

boost, or reverse buck-boost operation to the input

port from 2-cell to 4-cell batteries.

Applications

▪ 2-cell to 4-cell tablets, Ultrabooks, notebooks,

power banks, and any USB-C interface portable

device requiring batteries

The RAA489108 provides SMBus/I C serial

communication that enables programming of many

critical parameters to deliver a customized solution.
