Hi in-charge persn!

According to the specification sheet, we need to connect TS pin to GND when disabling charging operation.

Please let me know TS pin current when the TS pin is connected to GND.

Also, please provide document (block diagram, etc.) showing TS pin internal structure.

Regards

    The current is 38uA.

    When TS pin goes below 50mV (connected to GND), unit will shutdown.  Every 2 sec it will power back on and check TS pin, if it is still low unit will power back down.  Current to pin during shutdown is 0uA.
