DESCRIPTION
The TD230 is designed to control two N-channel
MOSFETs used as power switches in circuit
breaking applications.
Its current supervision and immediate action on
the switches ensure high security for the boards
and the supplies thus protected agains short-cir-
cuit or over current.
In case of short-circuit or over current detection,
the TD230 immediately switches off the corre-
sponding MOSFET, thus disconnecting the board
from the supply. After several automatic restart at-
tempts, a definitive shutdown of the circuit is done
if the shortcuircuit or over current persists over an
externally adjustable time, until the TD230 is reset
by temporary INHIBIT signal or temporary switch-
ing off of the power supply (hot disconnection/re-
connection).
If the board is disconnected from the positive sup-
ply by the TD230 it will automatically be disjoncted
from the negative supply too.
TD230 integrates an induction step-up converter
that provides 13.5V above the positive rail to drive
the high side MOSFET.
