ISL9238C

Buck-Boost Narrow VDC Battery Charger with SMBus Interface and USB OTG

The ISL9238C is a buck-boost Narrow Output Voltage

DC (NVDC) charger. The ISL9238C provides NVDC

Features

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

batteries

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.

• Input voltage range: 3.9V to 23.4V (no dead zone)

• System output voltage: 2.4V to 18.304V

• Autonomous charging option (automatic completion

of charging)

In Charging mode, the ISL9238C 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 ISL9238C 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 ISL9238C can operate with only a

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

Intel IMVP8 compliant systems, the ISL9238C

includes PSYS (system power monitor) functionality,

which provides an analog signal representing total

platform power. 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

• Allows 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

• 100% 2-FET Buck only mode option

• Battery Ship mode option

The ISL9238C supports reverse buck, boost, or

buck-boost operation to the input port from 2- to 4-cell

batteries.

• SMBus and auto-increment I C compatible

• 4x4 32 Ld TQFN package

The ISL9238C provides SMBus/I C serial

communication that allows programming of many

critical parameters to deliver a customized solution.

Applications

• 2- to 4-cell tablets, Ultrabooks, notebooks, power

banks, and any USB-C interface portable device

requiring batteries
