DESCRIPTION
The LTC®4066/LTC4066-1 are USB power managers and Li-Ion battery chargers
designed to work in portable battery-powered applications. The parts control
the total current used by the USB peripheral for operation and battery
charging. The total input current can be limited to 100mA, 500mA or
“unlimited” (i.e., above 2A). Battery charge current is automatically reduced
such that the sum of the load current and the charge current does not exceed
the programmed input current limit.
The LTC4066/LTC4066-1 include a standalone constant current/constant-voltage
linear charger for single cell Li-ion batteries. The float voltage applied to
the battery is held to a tight 0.8% tolerance, and charge current is
programmable using an external resistor to ground. A programmable end-of-
charge status output (CHRG) indicates full charge. BAT pin charge and
discharge currents can be monitored via an analog output (ISTAT). Total charge
time is programmable by an external capacitor to ground. When the battery
drops 100mV below the float voltage, automatic recharging of the battery
occurs. Also featured is an NTC thermistor input used to monitor battery
temperature while charging.
