I/O DESCRIPTION AND REQUIRED COMPONENTS NAME bq24060/64 bq24061 bq24063 Charge Input Voltage and internal supply. Connect a 1- µF (minimum) IN 1 1 1 I capacitor from IN to VSS. CIN≥ COUT 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- µF 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 µF (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. 6 Submit Documentation Feedback |
