NAME
FUNCTION
12, 13
DC
DC Input Supply. Connect DC to a 4.5V to 7V charging source. Bypass DC to GND with a 1F
or larger capacitor. DC takes priority over USB when both are present (MAX8601). Both DC
inputs should be connected together externally.
14
FLT
Fault Status Output. FLT goes low when either the prequal timer or the fast-charge timers
expire and the battery voltage is not above the required threshold. Clear the fault by raising
EN or removing input power.
—
9
USB
USB Input Source. Connect to a USB port. Bypass USB to GND with a 1F or larger capacitor.
—
6
USEL
USB Charge-Select Input. Logic input that determines the maximum charge current drawn
from the USB input. IBAT = 95mA when USEL = low, and IBAT = 475mA when USEL = high.
—
EP
Exposed Pad. Connect to the GND plane for optimum thermal dissipation.
