Connect to a wall adapter. FAULT (Pin 2) FAULT is an open-drai
17、n output indicating fault status. This pin is pulled to LOW under any fault conditions. Any time a FAULT condition happens, it will reset the counter of the charger. STATUS (Pin 3) STATUS is an open-drain output indicating charging and inhibit states. The STATUS pin is pulled LOW when the charger is
18、 charging a battery. It will be forced to high impedence when the charge current drops to IMIN. 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
19、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 volt
20、age 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 cha
21、rger 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 connectio
22、n 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.

The actual charge current may be affected by the thermal foldback function if the thermal dissipation capability is not enough or by the on resistance of the power MOSFET if the charger input voltage is too close to the output voltage. 4.
