LT1089

High Side Switch

FEATURES

DESCRIPTIO

The LT^®1089 is a logic driven, high current, high side

switch utilizing bipolar technology. The device is capable

of driving loads up to 7.5A with a low series drop of only

1.5V, and the series drop is specified over the full range of

switch currents. The device has internal current limiting

and thermal overload protection. The input logic is

designed so that the output can drive loads referenced

either above or below the device ground pin. Either

positive or negative logic can be used to drive the input.

The device is available in both TO-3 metal can and TO-220

plastic packages.
