SYNCHRONOUS SWITCHMODE, LI-ION AND LI-POL CHARGE MANAGEMENT

IC WITH INTEGRATED POWERFETS (bqSWITCHERE)

FEATURES

DESCRIPTION

Ideal For High-Efficient Charger Designs For

Single-, Two- or Three-Cell Li-Ion and Li-Pol

Battery Packs

The bqSWITCHER™ series are highly integrated

Li-ion and Li-polymer switch-mode charge

management devices targeted at a wide range of

portable applications. The bqSWITCHER™ series

offers integrated synchronous PWM controller

and power FETs, high-accuracy current and

voltage regulation, charge preconditioning,

charge status, and charge termination, in a small,

thermally enhanced QFN package. The

system-controlled version provides additional

inputs for full charge management under system

control.

Integrated Synchronous Fixed-Frequency

PWM Controller Operating at 1.1 MHz with 0

to 100% Duty Cycle

Integrated PowerFETs For Up To 2-A Charge

Rate

High-Accuracy Voltage and Current

Regulation

Available In Both Stand-Alone (Built-In

Charge Management and Control) and

System-Controlled (Under System

Command) Versions

The bqSWITCHER charges the battery in three

phases: conditioning, constant current, and

constant voltage. Charge is terminated based on

Charge Completion, Fault, and AC-Adapter

Present Conditions

user-selectable minimum current level.

programmable charge timer provides a safety

backup for charge termination. The

bqSWITCHER automatically re-starts the charge

cycle if the battery voltage falls below an internal

threshold. The bqSWITCHER automatically

enters sleep mode when V supply is removed.

Optional Battery Temperature Monitoring

APPLICATIONS

Automatic Sleep Mode for Low Power

Consumption

Handheld Products

System-Controlled Version Can Be Used In

NiMH and NiCd Applications

Portable Media Players

Industrial and Medical Equipment
