Hybrid Power Boost (HPB) and Narrow VDC (NVDC) Combo Battery Charger

with SMBus Interface

The ISL95522 is a highly versatile combination battery

charger configurable for operating as either a Hybrid

Features

• Configurable as an HPB charger or NVDC charger

Power Boost (HPB) charger or a Narrow VDC (NVDC)

charger, supporting 2-, 3-, or 4-cell batteries. Both

configurations allow the battery to work with the adapter

to supply the system load when it exceeds the adapter

capability, referred to as system Turbo mode. The HPB

charger configuration reverse-boosts battery energy to

the system bus to help the adapter provide the system

power in Turbo mode. The NVDC charger configuration

quickly turns on BGATE, which enables the battery to

help the adapter provide the system power in Turbo

mode.

• Compliant with Intel PROCHOT# and PSYS

requirements

• Adapter current monitor and battery discharging

current monitor

• Uses NFET for all the switches

• Supports battery removal during Battery Learn

mode

• Actively controlled inrush current to prevent FET

damage

The ISL95522 uses N-channel MOSFETs (NFETs) for

all the switches to achieve the best performance and

lowest BOM cost. The internal charge pump can turn on

all the NFETs quickly or slowly, depending on the

circumstance or need. The ability to quickly turn on

NFETs prevents system bus voltage drop when the

battery is suddenly removed in Turbo mode or in Battery

Learn mode.

• SMBus programmable settings and high accuracy

• Comprehensive protection features include:

• PROCHOT# indicator for system low voltage,

adapter overcurrent, battery overcurrent, or

system overheating

• Hardware-based adapter current and battery

current limits

The ISL95522 provides many protection features,

including a PROCHOT# indicator for system low

voltage, adapter overcurrent, battery overcurrent, or

overheating, with an array of SMBus programmable

parameters for maximum flexibility. It also features a

hardware-based adapter-current limit and battery-current

limit in addition to SMBus programmable limits.

• Supports sudden battery removal in system Turbo

mode

• 16 switching frequency options from 350kHz to 1MHz

• Low quiescent current

• SMBus and auto-increment I C compatible

• Renesas Robust Ripple Regulator (R3) modulation

scheme provides excellent light-load efficiency and

fast dynamic response

The ISL95522 provides a high accuracy adapter current

monitor, battery current monitor, and system power

monitor outputs. To provide maximum flexibility for

working with high and low power systems, it provides

several configurable current-sense resistor value options

to achieve the best trade-off of current sensing accuracy

vs power loss.

• 32 Ld 4x4mm QFN package

• Pb-free (RoHS compliant)

Applications

The ISL95522 uses the Renesas Robust Ripple Regulator

(R3™) modulation scheme to provide excellent

light-load efficiency and fast dynamic response. The

• Devices with rechargeable 2-, 3-, or 4-cell batteries
