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
μ
A standby current and 85
μ
A 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
μ
P. 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.
