LTC1156 - Quad High Side Micropower MOSFET Driver with Internal Charge Pump
Included on chip is independent over-current 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 LTC1156 operates off of a 4.5V to 18V supply and is well suited for battery-powered applications, particularly where micropower "sleep" operation is required.
The LTC1156 is available in both 16-pin DIP and 16-pin SOL packages.
