DESCRIPTION
The LTC
®
4078/LTC4078X are standalone linear chargers
that are capable of charging a single-cell Li-Ion/Polymer
battery from both wall adapter and USB inputs. The chargers
can detect power at the inputs and automatically select
the appropriate power source for charging.
No external sense resistor or blocking diode is required
for charging due to the internal MOSFET architecture. The
LTC4078/LTC4078X feature a maximum 22V rating for both
wall adapter and USB inputs, although charging stops if
the selected power source exceeds the overvoltage limit.
Internal thermal feedback regulates the battery charge
current to maintain a constant die temperature during
high power operation or high ambient temperature con-
ditions. The float voltage is fixed at 4.2V and the charge
current is programmed with an external resistor. The
LTC4078/LTC4078X terminate the charge cycle when the
charge current drops below the programmed termination
threshold after the final float voltage is reached.
Other features include battery present detection, automatic
recharge, undervoltage lockout, charge status outputs, and
“power present” status outputs to indicate the presence of
wall adapter or USB power. The device is offered in a low
profile (0.75mm) 3mm
