NCV8878: Automotive Grade Start-Stop Non-Synchronous Boost Controller
The NCV8878 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 NCV8878 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.
Features- Automatic enable below 7.3 V (factory programmable)
- -40 C to 150 C operation
- Low quiescent current in Sleep mode (<12 µA typical)
- Status function
- Disable function
| Benefits- Extra functionality in compact SOIC8
- Automotive Grade
- Meets Automotive Low Iq requirements
- Provides operating status to a micro-controller
- Permits disabling by a micro-controller
