DESCRIPTION
The LTC®4096/LTC4096X are standalone linear chargers
that are capable of charging a single-cell Li-Ion or Li-Poly-
mer 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.
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 LTC4096
terminates the charge cycle when the charge current drops
below the user programmed termination threshold after
the final float voltage is reached. The LTC4096 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 trickle charge (LTC4096 only), auto-
matic recharge, undervoltage lockout, charge status output
and power present output with 120mA drive capability.
