POWER MANAGEMENT
Pin Descriptions (Cont.)
Pin
Pin Name
Pin Function
1
VCC
Supply pin – connect to adapter power
2
VCCIL
Adapter input voltage – this pin provides a bias voltage approximately equal to the adapter
input voltage. When charging, the output current will be reduced by the load current on
VCCIL.
3
VOUT
Charger output – connect to battery
4
IPRGM
Current limit program pin for charge and LDO-mode – requires a resistor to ground to
program fast-charge current.
5
ITERM
Selection for current termination and pre-charge current – requires a resistor to ground to
program pre-charge and termination current.
6
GND
Ground
7
EN/NTC
Combined device enable/disable and NTC input pin – logic low disables the device.
Analog voltages between 0.3VCC and 0.75VCC enable the NTC function. Voltages above
95% of VCC force the NOBAT output high.
8
NOBAT
Battery Present Indicator – this output goes high when the NTC voltage exceeds 95% of
VCC indicating the battery and NTC have been removed.
9
RTIME
Charge time programming resistor – connect a resistor between RTIME and GND to
program the charge time. Force the pin to GND to disable the timer. Force the pin to VCC
to select LDO-mode.
10
CHRGB
Output status indicator designed to drive two LEDs. Connect cathode of the ‘charging’
LED to this pin to indicate charge in progress. Connect the anode of the ‘charge’
completed to this pin to indicate charge complete.
T
Thermal Pad
Pad is for heatsinking purposes
–
not connected internally. Connect exposed pad to
ground plane with thermal vias directly under pad.
