_______________General Desc ription
The MAX1647/MAX1648 provide the power control neces-
sary to charge batteries of any chemistry. In the MAX1647,
all charging functions are controlled via 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 MAX1647 func-
tions as a level 2 charger, compliant with the Duracell/Intel
Smart Battery Charger Specification. The MAX1648 omits
the SMBus serial interface, and instead sets the charge
voltage and current proportional to the voltage applied to
external control pins.
In addition to the feature set required for a level 2 charger,
the MAX1647 generates interrupts to signal the host when
power is applied to the charger or 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 batteries have completed charge without interrogating
the battery.
The MAX1647 is available in a 20-pin SSOP with a 2mm
profile height. The MAX1648 is available in a 16-pin SO
package.
