Automotive Multi-Output Power Management IC (PMIC) for Safety Applications

Favorite

Overview

The NCV97200 is a 2−output monolithic regulator consisting of 1 buck regulator and 1 boost regulator with supervisory functions including window voltage monitoring on all outputs and a window watchdog. This product is ideal for ADAS (Advanced Driver Assistance Systems) applications and utilizes an independent voltage reference and an adjustable independent oscillator to realize the supervisory features.A 40 V non−synchronous buck regulator converts the battery supply voltage to a 3.3 V output, and delivers up to 3 A (peak). This output rail may be used as the low voltage input voltage for the non−synchronous secondary boost converter. The secondary boost is fixed and is intended to supply a low current 5.0 V rail for In−Vehicle Networking circuits (IVN).All internal MOSFETs are N−channel devices, and a bootstrap circuit is used to drive the buck high−side MOSFET. Both SMPS outputs use peak current mode control with internal slope compensation. The IC incorporates an internal regulator that supplies charge to the low−voltage gate drivers.The NCV97200 is a functional safety solution that reduces the time required to develop safety systems that comply with the International Standards Organization (ISO) 26262. The device includes a range of integrated safety features such as dedicated feedback references, output voltage monitoring, and window watchdog.
