Chemistry-Independent Battery Chargers
_______________General Description
The MAX1647/MAX1648 provide the power control neces-
sary to charge batteries of any chemistry. In the MAX1647,
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
MAX1647 functions 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.
