Pin No. Pin Symbol Function 1 DISB Disable input. This part is disabled when this pin is brought low. 2 ISNS Current sense input. Connect this pin to the source of the external N−MOSFET, through a current−sense res- istor to ground to sense the switching current for regulation and current limiting. 3 GND Ground reference. 4 GDRV Gate driver o.
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.
Features
• Automatic Enable Below Wake Up Threshold Voltage (Factory
Programmable)
• Override Disable Function
• Boost Mode Operation at Regulation Set Point
• $2% Output Accuracy Over Temperature Range
• Peak Current Mode Control with Internal Slope Compensation
• Externally Adjustable Freq.
