1 / 16 page 1 LTC1154 DESCRIPTIO S FEATURE High-Side Micropower MOSFET Driver s Fully Enhances N-Channel Power MOSFETs s 8 µA IQ Standby Current s 85 µA IQ ON Current s No External Charge Pump Capacitors s 4.5V to 18V Supply Range s Short-Circuit Protection s Thermal Shutdown via PTC Thermistor s Status Output Indicates Shutdown s Available in 8-Pin SOIC The LTC1154 single high-side gate driver allows using low cost N-channel FETs for high-side 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. Micropower opera- tion, with 8 µA standby current and 85µA operating cur- rent, allows use in virtually all systems with maximum efficiency. Included on chip is programmable over-current sensing. A time delay can be added to prevent false triggering on high in-rush current loads. An active high shutdown input is also provided and interfaces directly to a standard PTC thermistor for thermal shutdown. An open-drain output is provided to report switch status to the µP. An active low enable input is provided to control multiple switches in banks. The LTC1154 is available in both 8-pin DIP and 8-pin SOIC packages.
