threshold. The 1.5ms filter time (t TERM ) on the internal
comparator ensures that transient loads of this nature do
not result in premature charge cycle termination. Once the
average charge current drops below I DETECT , the charger
terminates the charge cycle.
The CHRG output is in a pull-down state while charging
and in a high impedance state once charging has stopped.
Figure 4 describes the operation of the LTC4062 charger
when charge current termination is used.
When the charger is set for charge current termination and
the battery is removed from the charger, a sawtooth
waveform of several hundred mV will appear at the charger
output. This is caused by the repeated cycling between
termination and recharge events. This cycling results in
pulsing at the CHRG output. If an LED is connected to this
pin, it will exhibit a pulsing pattern, indicating to the user
that a battery is not present. The frequency of the sawtooth
is dependent on the amount of output capacitance.
