Pin No. Pin Symbol Function 1 STATUS This is an open−drain diagnostic. IC status operation flag indicator. This output is a logic low when IC VOUT is below the wake up threshold voltage (Thic,en) and device is active. A pull−up resistor of around 80 kW should be connected between STATUS and a microcontroller reference. This output is a logic high when.
include, cycle-by-cycle current limiting 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.
