4 / 16 page 4 FN9215.1 March 20, 2007 Pin Description Typical Application PIN # PIN NAME DESCRIPTION 1, 15, 16 VIN VIN is the input power source. It is recommended to have a 1 Ω resistor in series with the input decoupling capacitor to prevent an over-shoot voltage when the input cable is plugged in. 2GRN Open-drain LED drive pin. This pin sinks a constant-current 10mA to drive a green LED in a bi-color LED pack. 3RED 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. 7EN 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. 9IREF 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.
