The LTC
1155 dual high side gate driver allows using low
cost N-channel FETs for high side switching applications.
An internal charge pump boosts the gate above the posi-
tive rail, fully enhancing an N-channel MOSFET with no
external components. Micropower operation, with 8
μ
A
standby current and 85
μ
A operating current, allows use in
virtually all systems with maximum efficiency.
Included on-chip is overcurrent sensing to provide auto-
matic shutdown in case of short circuits. A time delay can
be added in series with the current sense to prevent false
triggering on high in-rush loads such as capacitors and
incandescent lamps.
The LTC1155 operates off of a 4.5V to 18V supply input
and safely drives the gates of virtually all FETs. The
LTC1155 is well suited for low voltage (battery-powered)
applications, particularly where micropower “sleep” op-
eration is required.
The LTC1155 is available in both 8-pin PDIP and 8-pin SO
packages.
