DESCRIPTIO
Fully Enhances N-Channel Power MOSFETs 12µA Standby Current Operates at Supply Voltages from 9V to 24V Short Circuit Protection Easily Protected Against Supply Transients Controlled Switching ON and OFF Times No External Charge Pump ponents patible With Standard Logic Families Available in 8-Pin SOIC
The LTC1255 dual high-side driver allows using low cost N-channel FETs for high-side industrial and automotive switching applications. An internal charge pump boosts the gate drive voltage above the positive rail, fully enhancing an N-channel MOS switch with no external ponents. Low power operation, with 12µA standby current, allows use in virtually all systems with maximum efficiency. Included on-chip is independent overcurrent sensing to provide automatic shutdown in case of short circuits. A time delay can be added to the current sense to prevent false triggering on high in-rush current loads. The LTC1255 operates from 9V to 24V supplies and is...
