Figure 1 –
Typical Application – 750mA adapter charge current and 500mA or 100mA maximum
USB charge currents. A grounded spare pin in the USB power cable can be used to sense when
the 500mA USB current power source is being used. This application also uses three LED
indicators for Power attached, Battery Charging and Battery full. This configuration also
implements circuitry to lockout battery charging if the battery is less than 0C or greater than 60C.
