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.

Battery Connection. The IC delivers charging current and monitors battery voltage using BAT.
Bypass BAT to GND with a 2.2µF or larger ceramic capacitor. Connect both BAT inputs
together externally (MAX8601). BAT is high impedance when the IC is disabled.
DC Charge-Current Programming Input. Connect a resistor from SETI to GND to set the
maximum charging current when using the DC input, the prequal current from either input,
and the CHG turn-off threshold.
Thermistor Input. Connect a 10kΩ NTC thermistor, in close proximity to the battery, from THM
to ground to monitor the battery temperature. Connect THM to GND to disable the thermistor
functionality. The IC suspends charging when RTHM is outside the hot and cold limits.
Ground
Timing Capacitor Input. Connect a capacitor from CT to GND to set the precharge timeout,
top-off time, and fast-charge timeout. Connect CT to GND to disable the timers.
No Connection. Make no external circuit connection.
Active-Low Enable Input. Drive low or connect EN to GND to enable the charger. Drive EN
high to disable the charger.
Power-OK Monitor. POK is an open-drain output that pulls low when a valid charging source is
detected at either DC or USB (MAX8601). POK is high impedance when EN is high.
Charging-Status Output. CHG goes low when the battery is above 3V and being charged with
a current greater than 7.5% of the current programmed with RSETI. CHG is high impedance
when the charger is in prequal, top-off, or disabled.
