Product Overview

The LT1158CSW#PBF is a Half-bridge Driver comes with 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 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.
  • Drives gate of top side MOSFET above V+
  • Adaptive non-overlap gate drives
  • Continuous current limit protection
  • Auto shutdown and retry capability
  • Internal charge pump for DC operation
  • Built-in gate voltage protection
  • Compatible with current-sensing MOSFETs
  • TTL/CMOS input levels
  • Fault output indication
