FUNCTION
Battery Connection. The IC delivers charging current and monitors battery voltage using BAT. Bypass
BAT to GND with a 2.2μF or larger ceramic capacitor. Connect both BAT inputs together externally. BAT
is high impedance when the IC is disabled. Ensure that all BAT pins are connected together.
DC Charge-Current Programming Pin. Connect a resistor from SETI to GND to set the maximum charging
current (I BAT = 1500V/R SETI ), the prequal current, and the CHG done threshold. Monitor charging current
by measuring this pin voltage. SETI is high-impedance when EN is high, or DC is at GND.
Thermistor Input. Connect a 10k Ω NTC thermistor, in close proximity to the battery, from THM to ground
to monitor the battery temperature. The IC suspends charging when R THM is outside the hot and cold
limits. Disable thermistor functionality by connecting THM to GND. THM is high impedance when EN is
high or DC is at GND.
Ground
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. CT is high impedance when EN is
high or DC is at GND.
No Connection. Make no external circuit connection.
Active-Low Enable Input. Drive low or connect EN to GND to enable the charger. Drive EN high to disable
the charger. EN has an internal 470k Ω pulldown resistance to GND.
Power-OK Monitor. POK is an open-drain output that pulls low when a valid charging source is detected.
POK is high impedance when DC voltage is outside valid range. POK remains active monitoring DC with
the charger enabled or disabled.
