Single-/Dual-Input 1-Cell Li+ Chargers with
OVP Protection and Programmable Charge Timer
General Description
The MAX8600/MAX8601 single-/dual-input linear bat-
tery chargers safely charge single-cell Li+ batteries.
The 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 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/undertemperature, and charging time. The charg-
er timeout protection is programmable. The charger
status is indicated by three open-drain outputs.
The MAX8601 automatically selects between either a
USB or AC adapter input source. The AC adapter
charge current is programmable, while USB charge
current is set not to exceed either 100mA or 500mA,
depending on the USEL input. The MAX8600 is a sin-
gle-input charger with no USB source input.
The MAX8600/MAX8601 are available in a 3mm x 3mm
power-enhanced TDFN package.
