XC8107
Series
85mΩ High Function Power Switch
ETR33003-004
■GENERAL
DESCRIPTION
The XC8107 series is a P-channel MOSFET power switch IC with a low ON resistance. A current limit, reverse current
prevention (prevents reverse current from V
OUT
to V
IN
), soft start, thermal shutdown, and an under voltage lockout (UVLO) are
incorporated as protective functions. A flag function monitors the power switch status. The flag output has N-channel open
drain configuration, and it outputs Low level signal when over-current or overheating is detected, or when the reverse current
prevention is operated. The voltage level which is fed to CE pin determines the status of XC8107. The logic level of CE pin is
selectable between either one of active high or active low.
