LTC1156

Quad High Side

Micropower MOSFET Driver

with Internal Charge Pump

DESCRIPTIO

EATURE

■

No External Charge Pump Components

Fully Enhances N-Channel Power MOSFETs

16 Microamps Standby Current

The LTC1156 quad 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 16µA standby current and 95µA operating

current, allows use in virtually all systems with maximum

efficiency.

95 Microamps ON Current

Wide Power Supply Range 4.5V to 18V

Controlled Switching ON and OFF Times

Replaces P-Channel High Side Switches

Compatible with Standard Logic Families

Available in 16-pin SOL Package

Included on chip is independent over-current sensing to

provide automatic shutdown in case of short circuits. A

time delay can be added to the current sense to prevent

false triggering on high in-rush current loads.

Battery Charging and Management

Low Frequency H-Bridge Driver

Stepper Motor and DC Motor Control

The LTC1156 operates off of a 4.5V to 18V supply and is

well suited for battery-powered applications, particularly

where micropower “sleep” operation is required.

The LTC1156 is available in both 16-pin DIP and 16-pin

SOL packages.
