Charge Prequal Output. Active-low, open-drain output pulls low when the charger enters the prequal state.
See Figure 5.
DC Power Input. DC is capable of delivering up to 2A to SYS. DC supports both AC adapter and USB inputs. The
DC current limit is set with PEN1, PEN2, USUS, and R
together externally.
Charger Enable Input. Connect CEN to GND to enable battery charging when a valid source is connected at DC
or USB. Connect to VL or drive high with a logic signal to disable battery charging.
DC Input Limit Control. If PEN1 is high, the DC input current limit is 3000/R
by PEN2 and USUS. See Table 2.
