Pin Description
Typical Application
PIN #
PIN NAME
DESCRIPTION
1, 15, 16
VIN
VIN is the input power source. VIN can withstand up to 28V input.
2
GRN
Open-drain LED drive pin. This pin sinks a constant-current 10mA to drive a
green
LED in a bi-color LED pack.
3
RED
Open-drain LED drive pin. This pin sinks a constant-current 10mA to drive a
red
LED in a bi-color LED pack.
4
TIME
Timer Programming Input. The TIME pin determines the oscillation period by connecting a timing capacitor between this
pin and GND. The oscillator provides a time reference for the charger.
5
GND
GND is the connection to system ground.
6
DT
Delta Temperature Setting Input. This pin sets the temperature difference before and after the charging starts. This pin can
also be used as an indication whether or not the charger is charging.
7
EN
Enable Input. Connect EN LOW to enable the charger. Pull it HIGH or leave it floating to disable the charger. This pin is
pulled up to 2.9V when left floating.
8
V2P9
Untrimmed 2.9V voltage output. This pin outputs a 2.9V voltage source when the input voltage is above POR threshold,
independent on the EN pin input. The V2P9 output is used to power the LEDs, the NTC circuit, or for other functions. The
maximum output current is 30mA. This output can also be used as an indication for adapter presence.
9
IREF
This is the programming input for the constant charging current in a linear charger. In the typical application of a dual-mode
charger, the IREF pin programs the trickle charge current as well as the protection current level.
10
IMIN
IMIN is the programmable input for the end-of-charge current.
11
TEMP
Temperature setting input. An external NTC thermistor is connected to this pin for ambient temperature sensing.
12
VSEN
Battery remote voltage sensing feedback pin. This pin allows remote sense of the battery pack voltage. Connect this pin
as close as possible to the battery positive terminal with a separate trace to minimize the impact of parasitic resistance.
This pin also serves the function of compensating for voltage drop caused by the connector contact resistance.
13, 14
BAT
BAT is the charger output.
-
EPAD
Exposed Pad. This pad is internally connected to GND. Connect as much copper as possible to this pad on the component
or other layers through thermal vias to maximize the thermal performance.
