The LTC1255 is a dual 24V high-side MOSFET driver that 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.
The LTC1255 is a dual high‑side driver that enables the use of low‑cost N‑channel MOSFETs for high‑side switching in industrial and automotive systems. It features an internal charge pump that raises the gate drive voltage above the supply rail, short‑circuit protection, and a low standby current of 12 µA.
The device operates from 9 V to 24 V supplies and is offered in 8‑pin DIP and 8‑pin SOIC packages. Typical applications include solenoid, DC motor, stepper motor, lamp, and relay drivers, as well as low‑frequency H‑bridge implementations.
