General Description
The G562 is an integrated power switch with
over-voltage and user-programmable current limit pro-
tection. The current limiting and thermal shutdown
prevent failures caused by increasing power dissipa-
tion when continuous heavy loads or short circuit oc-
curs. The current limit is user programmable.
It disconnect power from output rapidly if over voltage
is detected. In the case of an overcurrent condition, it
limits the system current at the threshold value, and if
the over current persists, switches the pass element
OFF after a blanking period. A built-in charge pump is
used to drive the N-channel MOSFET.
Other features include under-voltage lockout, battery
over-voltage lockout, and fault FLAG output that indi-
cate fault events.
The G562 is available in TDFN2X2-8 Package.
