19-1488; Rev 0; 7/99
Chemistry-Independent,
Level 2 Smart Battery Charger
General Description
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.
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.
The MAX1667 is available in a 20-pin SSOP with a 2mm
profile height.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
