Linear Technology LT1158
the LT1158 regulates short-circuit current in the top power MOSFET. By returning the FAULT output to the enable input, the LT1158 will automatically shut down in the event of a fault and retry when an internal pull-up current has recharged the enable capacitor.| Part No. | LT1158 |

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.
