LTC1255 - Dual 24V High-Side MOSFET Driver

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 components. 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 well suited for industrial and automotive applications. The LTC1255 is available in both an 8-pin DIP and an 8-pin SOIC.
