The NCV887103D1R2G is an automotive-grade, adjustable output non-synchronous boost controller designed to drive an external N-channel MOSFET. It operates using peak current mode control with internal slope compensation and features an internal regulator for gate driver supply. The device supports a wide input voltage range from 3.2 V to 40 V DC, with a maximum load dump voltage of 45 V. Key protection features include undervoltage lockout, cycle-by-cycle current limiting, hiccup-mode short-circuit protection, and thermal shutdown. The controller also incorporates an internally-set soft-start mechanism and a low quiescent current sleep mode. The switching frequency is externally synchronizable, and the device is AEC-Q100 qualified, making it suitable for automotive applications. The NCV887103D1R2G is packaged in a Pb-free SOIC-8 format and is capable of sourcing and sinking gate drive currents of 575 mA and 350 mA, respectively.
