描述
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 charger, 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 without interrogating the battery.
The MAX1667 is available in a 20-pin SSOP with a 2mm profile height.
