LT1910IS8#PBF

产品概述

The LT1910IS8#PBF is a protected high-side MOSFET Driver allows the use of 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 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 are 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 or transients may be present. The device will not sustain damage from supply transients of -15 to 60V.
