NAME
FUNCTION

1, 7
BAT
Battery Connection. The IC delivers charging current and monitors battery voltage using BAT.
Bypass BAT to GND with a 2.2F or larger ceramic capacitor. Connect both BAT inputs
together externally (MAX8601). BAT is high impedance when the IC is disabled.
2
SETI
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.
3
THM
Thermistor Input. Connect a 10k
Ω 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.
4
GND
Ground
55
CT
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.
6, 7, 9
—
N.C.
No Connection. Make no external circuit connection.
88
EN
Active-Low Enable Input. Drive low or connect EN to GND to enable the charger. Drive EN
high to disable the charger.
10
POK
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.
11
CHG
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.
