Pin Description
VIN (Pin 1, 15, 16)
VIN is the input power source. Connect to a wall adapter.
STAT2 (Pin 2)
STAT2 is an open-drain output to indicate the charger status.
This pin is pulled to LOW during charging and to HIGH when
not charging. When a fault situation occurs, the pin outputs a
one-speed blinking indication.
STAT1 (Pin 3)
STAT1 is an open-drain output to indicate the charger status.
The STAT1 pin is pulled LOW when the charger is charging a
battery and to HIGH when the charge finishes. This pin outputs
two different speeds of blinking signal depending on the type of
the fault case.
TIME (Pin 4)
The TIME pin determines the oscillation period by connecting a
timing capacitor between this pin and GND. The oscillator also
provides a time reference for the charger.
GND (Pin 5)
GND is the connection to system ground.
TOEN (Pin 6)
TOEN is the TIMEOUT enable input pin. Pulling this pin to
LOW disables the TIMEOUT charge-time limit for the fast
charge modes. Leaving this pin HIGH or floating enables the
TIMEOUT limit.
Typical Application
EN (Pin 7)
EN is the enable logic input. Connect the EN pin to LOW to
disable the charger or leave it floating to enable the charger.
V2P8 (Pin 8)
This is a 2.8V reference voltage output. This pin outputs a 2.8V
voltage source when the input voltage is above POR threshold
and outputs zero otherwise. The V2P8 pin can be used as an
indication for adapter presence. Use a 1F ceramic capacitor
to stabilize the internal linear regulator.
IREF (Pin 9)
This is the programming input for the constant charging
current.
IMIN (Pin 10)
IMIN is the programmable input for the end-of-charge current.
TEMP (Pin 11)
TEMP is the input for an external NTC thermistor. The TEMP
pin is also used for battery removal detection.
VBAT (Pin 12, 13, 14)
VBAT is the connection to the battery. Typically a 10F
Tantalum capacitor is needed for stability when there is no
battery attached. When a battery is attached, only a 0.1F
ceramic capacitor is required as the minimum decoupling
capacitor.
