FUNCTION
Input Supply Voltage. Bypass IN to GND with a 1μF or larger ceramic capacitor to improve line
noise and input transient rejection.
Internally Generated Logic Supply for IC. Bypass VL to GND with a 0.47μF ceramic capacitor.
Ground. Connect GND and exposed pad to a large copper ground plane for maximum power
dissipation. Connect GND to the exposed paddle directly under the IC.
Charge-Current Program and Fast-Charge Current Monitor. Output current from ISET is 1.08mA
per amp of battery charging current. Set the charging current by connecting a resistor from ISET
to GND. Fast-charge current = 1302V / R ISET ? .
Charging Indicator. CHG is an open-drain output that goes low (LED capable) when charging
begins. CHG is high impedance when the battery current drops below 10% of the fast-charging
current, or when the IC is disabled. Connect a pullup resistor to the μP’s I/O voltage when
interfacing with a μP logic input.
Logic-Level Enable Input. Drive EN high to disable charger. Pull EN low or leave unconnected for
normal operation. EN has an internal 200k ? pulldown resistor.
Logic-Level Enable Input. Drive EN low to disable charger. Pull EN high for normal operation. EN
has no internal pullup or pulldown resistor.
Input Status Indicator. ACOK is an open-drain output that asserts low when V IN < +7V and (V IN –
V BATT ) ≥ 40mV. ACOK requires an external 100k ? pullup resistor. ACOK is high impedance
during shutdown.
Li+ Battery Connection. Bypass BATT to GND with a ceramic capacitor of at least 2.2μF per
ampere of charge current.
Exposed Paddle. Connect the exposed paddle to a large ground plane for maximum power
dissipation. Connect GND to the exposed paddle directly under the IC.
