I/O DESCRIPTION AND REQUIRED COMPONENTS
NAME bq24060/64 bq24061 bq24063
Charge Input Voltage and internal supply. Connect a 1- µ F (minimum)
IN 1 1 1 I
capacitor from IN to VSS. C
IN
≥ C
OUT
Safety Timer Program Input, timer disabled if floating. Connect a resistor to
TMR 2 2 2 I
VSS pin to program safety timer timeout value
STAT1 3 3 3 O Charge Status Output 1 (open-collector, seeTable 3 )
STAT2 4 4 4 O Charge Status Output 2 (open-collector, see Table 3 )
VSS 5 5 5 I Ground
Charge current set point, resistor connected from ISET to VSS sets charge
ISET 6 6 6 O
current value. Connect a 0.47- µ F capaciator from BAT to ISET.
PG 7 7 — O Power Good status output (open-collector), active low
CE — 8 7 I Charge enable Input. CE = LO enables charger. CE = HI disables charger.
Termination enable Input. TE = LO enables termination detection and battery
TE — — 8 I absent detection. TE = HI disables termination detection and battery absent
detection.
Temperature Sense Input, connect to battery pack thermistor. Connect an
TS 8 — — I
external resistive divider to program temperature thresholds.
Battery Voltage Sense Input. Connect to the battery positive terminal. Connect
BAT 9 9 9 I
a 200- Ω resistor from BAT to OUT.
Charge current output. Connect to the battery positive terminal. Connect a 1-
OUT 10 10 10 O
µ F (minimum) capacitor from OUT to VSS.
There is an internal electrical connection between the exposed thermal pad
Exposed and Vss pin of the IC. The exposed thermal pad must be connected to the
Thermal Pad Pad Pad same potential as the VSS pin on the printed circuit board. Do not use the
Pad thermal pad as the primary ground input for the IC. VSS pin must be
connected to ground at all times.
