3.10 Battery Charger Interface
Figure 3-10-1 BATTERY CHARGER BLOCK
The MAX8922 linear battery chargers safely charges single-cell Li+ batteries.
Charging rate is optimized to accommodate the thermal characteristics of a given application.
There is no need to reduce the maximum charge current or worst-case charger power dissipation.
Charging is optimized for Li+ cells using a control algorithm that includes low-battery precharging,
voltage and current-limited fast charging, and top-off charging, while continuously monitoring for
input overvoltage and device over-temperature.
The charge current and termination threshold are programming by simple one wire serial interfaces.
The charger status is indicated by two open-drain outputs.
The AC adapter charger current is programming by external ISET1 resistor while USB charge
current is programming either 90mA or 400mA through one wire interface.
The MAX8922 is available in the tiny 10pin 2mm by 3mm TDFN package.
