NCV8876: Automotive Grade Start-Stop Non-Synchronous Boost Controller

The NCV8876 is a Non-Synchronous Boost controller designed to supply a minimum output voltage during Start-Stop vehicle operation battery voltage sags. The controller drives an external N-channel MOSFET. The device uses peak current mode control with internal slope compensation. The IC incorporates an internal regulator that supplies charge to the gate driver. Protection features include, cycle-by-cycle current limiting, protection and thermal shutdown. Additional features include low quiescent current sleep mode operation. The NCV8876 is enabled when the supply voltage drops below 7.3 V, with boost operation initiated when the supply voltage is below 6.8 V.

Features
  • Automatic enable below 7.3 V (factory programmable)
  • -40 C to 150 C operation
  • 2 V to 45 V operation
  • Low Quiescent Current in Sleep Mode (<12 uA Typical)
  • Status monitoring
Benefits
  • Extra functionality in compact SOIC8 package
  • Automotive grade
  • Operates through cranking and load dump
  • Meets Automotive Low Iq requirements
  • Provides operating status to microcontroller
Applications
  • Start-Stop applications
