TTL/CMOS Input Levels
Fault Output Indication 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.
A continuous current limit loop in the LT1158 regulates
short-circuit current in the top power MOSFET. Higher
start-up currents are allowed as long as the MOSFET VDS
does not exceed 1.2V. By returning the FAULT output to …
