POWER STATUS INDICATORS
The STAT pin is designed to source or sink current. LEDs
can be configured to indicate charging or battery full. The
battery full indicator can be connected to DCOK rather than
GND to insure it is off when the input power is removed
and the STAT pin and DCOK pin go to a high impedance
state.

INPUT POWER SOURCE DETECTION
In order to detect when the input power source has been
removed, the LX2206 requires that a small current (up to
200uA) momentarily flow out of the IN pin (in the reverse
direction). Once detected, the reverse IN current is shut off
(the IN pin becomes a very high impedance until an input
power source is later reapplied). In most applications, there
is sufficient loading on the IN pin from external circuitry to
accomplish this, which includes the “Full” and/or “Power
On” LED loads and the TFB resistor string. If there is no
external load on the IN pin, then it is recommended to
provide a 15k resistor from IN to GND as shown below.
