DESCRIPTION
The LT
low cost N-channel power MOSFETs for high side switching
applications. It contains a completely self-contained charge
pump to fully enhance an N-channel MOSFET switch with
no external components.
When the internal drain comparator senses that the switch
current has exceeded the preset level, the switch is turned
off and a fault fl ag is asserted. The switch remains off for
a period of time set by an external timing capacitor and
then automatically attempts to restart. If the fault still
exists, this cycle repeats until the fault is removed, thus
protecting the MOSFET. The fault fl ag becomes inactive
once the switch restarts successfully.
The LT1910 has been specifi cally designed for harsh
operating environments such as industrial, avionics and
automotive applications where poor supply regulation and/
or transients may be present. The device will not sustain
damage from supply transients of –15V to 60V.
The LT1910 is available in the SO-8 package.
