NCV8877  
Automotive Grade  
Start-Stop Non-Synchronous  
Boost Controller  
The NCV8877 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 and  
thermal shutdown.  
Additional features include low quiescent current sleep mode  
operation. The NCV8877 is enabled when the supply voltage drops  
below the wake up threshold. Boost Operation is initiated when the  
supply voltage drops below the regulation set point.
