DESCRIPTION

NAME

OUT

NO.

Battery connection. System load may be connected in parallel to battery. Bypass OUT with at least

a 1-μF capacitor to GND, place close to the IC.

Input power, connected to external DC supply. Bypass IN with at least a 1-μF capacitor to GND,

place close to the IC.

Temperature qualification voltage input. Connect a negative temperature coefficient (NTC)

thermistor directly from TS to GND (AT103-2 recommended). Charge suspends when TS < V_HOTor

TS > V_COLD. Charge at 20% of ISET when V_COLD> TS > V_COOL. If TS function is not needed,

connect an external 10-kΩresistor from this pin to GND. Pulling TS < V_{TS_ENZ}disables the charger.

ISET

STAT

GND

Programs the device fast-charge current. An external resistor from ISET to GND defines fast charge

current value. Expected range is 30 kΩ (10 mA) to 375 Ω (800 mA). ICHG = K_ISET/ R_ISET

Precharge current is defined as 20% of ICHG. Termination current is defined as 10% of ICHG.

–

Open drain charger status indication output. Connect to pull-up rail via 10-kΩresistor.

LOW indicates charge in progress. HIGH indicates charge complete or charge disabled. When a

fault condition is detected, the STAT pin blinks at 1 Hz. If unsued, this pin can be left floating.
