LTC1155  
Dual High Side  
Micropower MOSFET Driver  
FEATURES  
DESCRIPTION  
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 8µA  
standby current and 85µA operating current, allows use  
in virtually all systems with maximum efficiency.

Replaces P-Channel High Side MOSFETs  
Included on-chip is overcurrent sensing to provide au-  
tomatic 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.

Compatible with Standard Logic Families

Available in 8-Pin SO Package  
APPLICATIONS  
TheLTC1155operatesoffofa4.5Vto18Vsupplyinputand  
safely drives the gates of virtually all FETs. The LTC1155  
is well suited for low voltage (battery-powered) applica-  
tions, particularly where micropower “sleep” operation  
is required.
