STANDALONE Li-ION SWITCH MODE BATTERY CHARGER
DESCRIPTION
FEATURES
The A4062 is a complete battery charger controller
for two (8.4V) cell lithium-ion batteries. With a 500kHz
switching frequency, the A4062 provides a small,
simple and efficient solution to fast charge Li-Ion
batteries from a wide range of supply voltages. An
external sense resistor sets the charge current. An
internal resistor divider and precision reference set
the final float voltage with ±1% accuracy.
When the input supply is removed, the A4062
automatically enters a low current sleep mode,
dropping the battery drain current to 20μA. An internal
comparator detects the near end-of-charge condition
while an internal timer sets the total charge time and
terminates the charge cycle.
Wide Input Supply Range: 8.9V to 20V
Current Mode PWM Controller DC-DC
±1% Charge Voltage Accuracy
±5% Charge Current Accuracy
End-of-Charge Current Detection Output
Charge Termination Timer
