Description

General part information

MAX20478 Series

The MAX20478 is a complete ASIL D-compliant system-on-a-chip (SoC) voltage monitor with two or three voltage monitor inputs. Inputs 1 and 2 can be configured to monitor a voltage between 0.5V and 3.6875V in 12.5mV steps, while input 3 can be configured to monitor a voltage between 0.5V to 5.6V in 20mV steps. Each input has programmable OV/UV thresholds of between 2.5% and 10% with ±0.8% accuracy. The MAX20478 also contains a programmable windowed watchdog. The MAX20478 significantly reduces system size and component count, while improving reliability, compared to separate ICs or discrete components. The device is designed to operate over the ambient temperature range of -40°C to +125°C.ApplicationsAdvanced Driver-Assistance SystemsAutonomous Driving Processing SystemsPower System Supervision and Microcontroller Unit/System-on-a-Chip MonitoringRemote Sensor Modules
