Buck-Boost Configurable Battery Charger with SMBus Interface and USB

Power Delivery

Aug 12, 2021

The ISL9241 is a digitally configurable buck-boost

battery charger that can support both Narrow Voltage

Features

• Buck-boost NVDC or hybrid power (turbo boost)

charger for 2-, 3-, or 4-cell Li-ion batteries using all

NFET transistors

Direct Charging (NVDC) and Hybrid Power Buck Boost

(HPBB/Bypass) charging and switch between the modes

using firmware control. Bypass mode is also supported

using the firmware of the controller, which allows the

adapter to provide power directly to the system. The

ISL9241 provides charging functionality, system bus

regulation, and protection features using only NFETs for

tablet, Ultrabook, and notebook platforms. The advanced

Renesas R3™ technology provides a high, light-load

efficient Charging mode. The ISL9241 takes input power

from a wide range of DC power sources (such as

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

• System/battery output voltage: 3.9V to 18.304V

• Bypass mode supported to connect system to adapter

• Autonomous charging option (automatic end of

charging)

• Adapter current and battery current monitor

(AMON/BMON)

conventional AC/DC charger adapters, USB Type-C

Power ports, and travel adapters) and safely charges

battery packs with up to 4-series cell Li-ion batteries.

• PROCHOT# open-drain output, IMVP compliant

• System power monitor PSYS output, IMVP8/9

compliant

The system power can be provided from the adapter,

battery, or a combination of both. The reconfigurable

internal registers of the charger allow the use of a smaller

inductor for the HPBB mode to achieve higher

• Internal 8-bit ADC for monitoring key parameters

• USB-C PD Fast Role Swap support and PPS support

efficiencies across multiple power levels. The ISL9241

can operate with only a battery, only an adapter, or both

connected. For Intel IMVP compliant systems, the

ISL9241 includes System Power monitor (PSYS)

functionality, which provides an analog signal

• Independent compensation pins for forward and

reverse operation (OTG) modes

• Supports supplemental power (Intel V

protection)

active

MIN

• Battery Ship mode: IC ultra-low power state

• Supports JEITA compliance using an NTC

• 4x4 32 Ld TQFN package

representing total platform power. The PSYS output

connects to a wide range of IMVP core regulators to

provide an IMVP compliant power domain function. The

ISL9241 supports reverse buck, boost, or buck-boost

operation to the adapter port (OTG mode) from 2- to

4-cell batteries. This allows configurations to support

USB-C Power Delivery (PD) output for Programmable

Power Supply (PPS) ports. The ISL9241 serial

Applications

• 2- to 4-cell tablets, notebooks, power banks, and any

USB-C interface portable device requiring batteries

communication uses SMBus/I C, which allows

programming of many key parameters to deliver a

customized solution.
