Pin Descriptions
VIN (Pin1)
VIN is the input power source. Connect to a wall adapter.
NC (Pin 2)
No connection for this pin.
STATUS (Pin 3)
STATUS is an open-drain output indicating charging and
inhibit states. The STATUS pin is pulled LOW when the
charger is charging a battery. It will be forced to high
impedence when the charge current drops to I
MIN
. This high
impedence mode will be latched until a recharge cycle or a
new charge cycle starts.
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.
EN (Pin 6)
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 7)
This is a 2.8V reference voltage output. This pin outputs a
2.8V voltage source when the input voltage is above POR
threshold, otherwise it outputs zero. The V2P8 pin can be
used as an indication for adapter presence.
IREF
(Pin 8)
This is the programming input for the constant charging
current. It maintains at 0.8V when the charger is in normal
operation.
VSEN (Pin 9)
VSEN is the remote voltage sense pin. Connect this pin as
close as possible to the battery pack positive connection. If
the VSEN pin is floating, its voltage drops to zero volt and
the charger operates in the trickle mode.
VBAT (Pin 10)
VBAT is the connection to the battery. Typically a 10µF
Tantalum capacitor is needed for stability when there is no
battery attached. When a battery is attached, only a 0.1µF
ceramic capacitor is required.
