„
„
„
„
„
„
The G562 is an integrated power switch with
over-voltage and user-programmable current limit protection. The current limiting and thermal shutdown
prevent failures caused by increasing power dissipation when continuous heavy loads or short circuit occurs. The current limit is user programmable.

Protection Status Flag Output
„ TDFN2X2-8 Package
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.
