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.

MARKING

DIAGRAM

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.
