TABLE 1. LM3658 Pin Description
Description
AC wall adapter input pin.
USB power input pin.
Power and signal ground pin.
Pulling this pin low limits the USB charge current to 100 mA. Pulling this pin high limits the USB
charge current to 500 mA.
Pulling this pin low enables the charger. Pulling this pin high disables the charger.
Active low open-drain output. Indicates charger status. This pin is capable of driving an LED as well
as GPIOs. See Operation Description section for more detail.
Active low open-drain output. Indicates charger status. This pin is capable of driving an LED as well
as GPIO. See Operation Description section for more detail.
A resistor is connected between this pin and GND. The resistor value determines the full-rate charge
current when using the AC source.
Battery temperature sense pin. This pin must be connected to battery pack’s temperature sense
output pin. See Operation Description section for more detail.
Positive battery terminal connection.
