The NCV97400 is a 4−output monolithic regulator consisting of 3 buck regulators and 1 boost regulator with supervisory functions including window voltage monitoring on all outputs and a window watchdog timer. 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 input voltage for the 2 synchronous secondary buck converters and the non−synchronous secondary boost converter. Each secondary buck is adjustable and can be set from 2.5 V to 0.8 V with 2 A peak current limit and can be supplied by up to 3.6 V from a separate supply. The secondary boost output voltage 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 bootstrap circuits are used to drive high side MOSFETs. All 4 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 NCV97400 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 timer.
