The LTC
®
4076 is a standalone linear charger that is capable
of charging a single-cell Li-Ion battery from both wall
adapter and USB inputs. The charger 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.
Internal thermal feedback regulates the battery charge
current to maintain a constant die temperature during high
power operation or high ambient temperature conditions.
The float voltage is fixed at 4.2V and the charge current
is programmed with an external resistor. The LTC4076
terminates the charge cycle when the charge current drops
below the user programmed termination threshold after
the final float voltage is reached. The LTC4076 can be put
into shutdown mode reducing the DCIN supply current to
20µA, the USBIN supply current to 10µA, and the battery
drain current to less than 2µA even with power applied
to both inputs.
Other features include automatic recharge, undervoltage
lockout, charge status output, power present status output
to indicate the presence of wall adapter or USB power and
high power/low power mode (C/5) for USB compatible
applications.
