DESCRIPTION
NO.
Charger input voltage from ac adapter. The AC pin can be left open or can be connected to
ground if the charger is not used.
Charger input voltage from USB port. The USB pin can be left open or can be connected to
ground if the charger is not used.
External charge current setting resistor connection for use with ac adapter
Sense input for the battery voltage. Connect directly with the battery.
Power output of the battery charger. Connect directly with the battery.
Battery temperature sense input
Indicates when a valid power supply is present for the charger (open drain)
Analog ground connection. All analog ground pins are connected internally on the chip.

Open drain reset output generated by user activated HOT_RESET
Open drain system reset output, generated according to the state of the VMAIN output
voltage. If the main output is disabled, RESPWRON is active (i.e., low).
Sets the reset delay time at RESPWRON. TPOR = 0: T
n(RESPWRON)
