DESCRIPTIO

The LT

of low cost N-channel power MOSFETs for high side

switching applications. It contains a completely self-con-

tained 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 flag 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 flag becomes inactive

once the switch restarts successfully.

The LT1910 has been specifically 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.
