NCV8871
Automotive Grade
Non-Synchronous Boost
Controller
The NCV8871 is an adjustable output nonsynchronous boost
controller which drives an external Nchannel 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 internallyset softstart, undervoltage
lockout, cyclebycycle current limiting, hiccupmode shortcircuit
protection and thermal shutdown.
Additional features include low quiescent current sleep mode and
externallysynchronizable switching frequency.
Features
Peak Current Mode Control with Internal Slope Compensation
1.2 V ±2% Reference voltage
Fixed Frequency Operation
Wide Input Voltage Range of 3.2 V to 40 Vdc, 45 V Load Dump
Input Undervoltage Lockout (UVLO)
Internal SoftStart
Low Quiescent Current in Sleep Mode
CyclebyCycle Current Limit Protection
HiccupMode Overcurrent Protection (OCP)
HiccupMode ShortCircuit Protection (SCP)
Thermal Shutdown (TSD)
