Single-Input 1-Cell Li+ Charger with
OVP Protection and Programmable Charge Timer
General Description
The MAX8600A single-input linear battery charger safe-
ly charges single-cell Li+ batteries. Charging is opti-
mized for Li+ cells using a control algorithm that
includes low-battery precharging, voltage and current-
limited fast-charging, and top-off charging, while con-
tinuously 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 ther-
mal characteristics of a given application. There is no
need to reduce the maximum charge current to accom-
modate 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 power-
enhanced TDFN package.
