FUNCTION
Charging-Status Output. CHG pulls low when the battery is above 2.5V and being charged with a current
greater than 6% of the current programmed with R SETI . CHG is high impedance when the charger is in
prequal, top-off, or disabled.
DC Input Source. Connect directly to a 4.5V to 6.0V charging source. Bypass DC to GND with 1μF or
greater. DC is overvoltage protected to 14V. Ensure that all DC pins are connected together.
Fault Status Output. FLT pin pulls low when the fast-charge or prequal timers expire and the battery
voltage is not above the required threshold. Clear the fault by raising EN or dropping DC to GND (remove
input power).
Exposed Pad. Connect EP to the GND plane for optimum thermal dissipation.
