MAX8600A

19-3205; Rev 1; 1/09 KIT ATION EVALU E L B A IL AVA Single-Input 1-Cell Li+ Charger with OVP Protection and Programmable Charge Timer General Description The MAX8600A single-input linear battery charger safely charges single-cell Li+ batteries. Charging is optimized for Li+ cells using a control algorithm that includes low-battery precharging, voltage and currentlimited fast-charging, and top-off charging, while continuously monitoring the battery for overvoltage, over/under temperature, and charging time. Charger timeout protection is programmable, and the status is indicated by three open-drain outputs. The MAX8600A linear charger optimizes charging time by adjusting the charge rate to accommodate the thermal characteristics of a given application. There is no need to reduce the maximum charge current to accommodate worst-case charger power dissipation. The MAX8600A is a variation of the MAX8600 with improved dropout and other spec changes. See Maxim’s website for an outline of MAX8600/MAX8600A differences. The MAX8600A is available in a 3mm x 3mm powerenhanced TDFN package. ♦ Low Dropout -0.188V at 0.75A ♦ Up to 1A Programmable Fast-Charge ♦ 5% Charge-Current Accuracy ♦ Logic-Low Enable Input ♦ 14V Input Overvoltage Protection ♦ Programmable On-Chip Charge Timer ♦ Battery Thermistor Input ♦ Three Charger-Status Outputs ♦ Thermally Optimized Charge Rate ♦ 14-Pin, 3mm x 3mm TDFN Package Features MAX8600A Ordering Information PART TEMP RANGE PIN-PACKAGE 14 TDFN-EP* (3mm ...
