MAX20481 Automotive Power System Monitor

Analog Devices MAX20481 Automotive Power System Monitor is a complete ASIL-compliant power system SoC (System-on-a-Chip) with up to seven voltage monitor inputs. Each input has programmable OV/UV thresholds of between 2.5% and 10% with ±1% accuracy. Two of the inputs have a separate remote ground-sense input for use with high-current SoC supplies. The MAX20481 contains a factory-programmable windowed watchdog with digital input pins to refresh and disable the watchdog. The active-low RESET pin of the device can be set at the factory to assert under various conditions. The MAX20481 significantly reduces system size and component count while improving reliability compared to separate ICs or discrete components. The MAX20481 meets ASIL B reliability levels in a standalone application. The device is designed to operate from -40°C to +125°C ambient temperature.
