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.

Fully Enhances N-Channel Power MOSFETs

8µA Standby Current

85µA ON Current

Short-Circuit Protection

Wide Power Supply Range: 4.5V to 18V

Controlled Switching ON and OFF Times

No External Charge Pump Components

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.

Laptop Power Bus Switching

SCSI Termination Power Switching

Cellular Phone Power Management

P-Channel Switch Replacement

Relay and Solenoid Drivers

The LTC1155 is available in both 8-pin PDIP and 8-pin

SO packages.

Low Frequency Half H-Bridge
