be preserved until the part is shut down using the
EN_HOLD (going low) or if the BAT and CHGIN supply
are removed.
(and not through EN_KEY), then when the CHGIN is
removed, the part will shut down and all I

back to what it was before. For example, if the ISET
code is set to 010 and USE_USB=H and the part was
turned on with EN_KEY, then when CHGIN is discon-
nected then reconnected, the charger will be set to
100mA. Then if any other command is sent, the ISET
code will remain 010.
