n Available in SO-8 Package The LTВ®1910 is a high side gate driver that allows the use of
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. n n n n n n n APPLICATIONS 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 …
