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 acmodate the thermal characteristics of a given application. There is no need to reduce the maximum charge current to acmodate 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 Ordering Information PART TEMP RANGE PIN-PACKAGE 14 TDFN-EP- (3mm x 3mm) (T1433-2) TOP MARK AEF Applications Cell Phones Digital Cameras PDAs GPS Portable Media Players MP3 Players Wireless Appliances MAX8600AETD+ -40°C to +85°C - EP = Exposed pad. +Denotes a lead(Pb)-free/Ro HS-pliant package.
