Hot-selling and scarce LT1158CSW-PBF Half Bridge N-Channel Power MOSFET Driver SOP16 spot stock

Product Descriptions

A single input pin on the LT®1158 synchronously controls  two N-channel power MOSFETs in a totem pole confi guration. Unique adaptive protection against shoot-through  currents eliminates all matching requirements for the two  MOSFETs. This greatly eases the design of high effi ciency  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  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.

An on-chip charge pump is switched in when needed to  turn on the top N-channel MOSFET continuously. Special  circuitry ensures that the top side gate drive is safely  maintained in the transition between PWM and DC operation. The gate-to-source voltages are internally limited to  14.5V when operating at higher supply voltages.
