Chemistry-Independent,

Level 2 Smart Battery Charger

General Description

____________________________Features

The MAX1667 provides the power control necessary to

charge batteries of any chemistry. All charging functions

are controlled through the Intel System Management Bus

(SMBus™) interface. The SMBus 2-wire serial interface

sets the charge voltage and current and provides thermal

status information. The MAX1667 functions as a Level 2

charger, compliant with the Duracell/Intel Smart Battery

Charger Specification.

ꢀ Charges Any Battery Chemistry: Li+, NiCd,

NiMH, Lead Acid, etc.

ꢀ SMBus 2-Wire Serial Interface

ꢀ Compliant with Duracell/Intel Smart Battery

Charger Specification Rev. 1.0

ꢀ 4A, 3A, or 1A (max) Battery Charge Current

ꢀ 5-Bit Control of Charge Current

ꢀ Up to 18.4V Battery Voltage

In addition to the feature set required for a Level 2 charg-

er, the MAX1667 generates interrupts to signal the host

when power is applied to the charger or when a battery is

installed or removed. Additional status bits allow the host

to check whether the charger has enough input voltage,

and whether the voltage on or current into the battery is

being regulated. This allows the host to determine when

lithium-ion (Li+) batteries have completed the charge with-

out interrogating the battery.

ꢀ 11-Bit Control of Voltage

ꢀ

1% Voltage Accuracy

ꢀ Up to +28V Input Voltage

ꢀ Battery Thermistor Fail-Safe Protection

ꢀ Greater than 95% Efficiency

ꢀ Synchronous Rectifier

The MAX1667 is available in a 20-pin SSOP with a 2mm

profile height.
