Note: The manufacturer provides a single datasheet file (LT1-158.pdf) that lists specifications for multiple related part numbers.

General Description

A single input pin on the LT®1158 synchronously controls two N-channel power MOSFETs in a totem pole configuration.

Unique adaptive protection against shoot-through currents eliminates all matching requirements for the two MOSFETs.

This greatly eases the design of high efficiency motor control and switching regulator systems.
