V
internal undervoltage lockout enables the main switch that
connects V
capacitor and a 1Ω resistor in series or use a 10µF
capacitor with at least 1Ω minimum ESR. This minimizes
the voltage transient that can occur when the input is hot
switched.
GND (Pin 2): Signal Ground for the LTC4410.
MODE (Pin 3): Mode Select Input. This pin selects the
maximum USB port current of either 100mA or 500mA.
When MODE is high, the current out of CHP will be I
1000. When MODE is low, the current out of CHP will be

CHP (Pin 5): Charger Program Output. This pin sources a
current that is used by the battery charger to control
charge current.
