The MAX20484 is a complete ASIL D compliant SoC power system monitor with up to five voltage monitor inputs. Each input has programmable OV/UV thresholds of between 2.5% and 10% with ±0.8% accuracy.
The MAX20484 contains a programmable flexible power sequence recorder (FPSR). This recorder stores power-up and power-down timestamps separately, and supports on/off and sleep/standby power sequences. The MAX20484 also contains a programmable challenge/response watchdog, which is accessible through the I2C interface, and an external clock/fault monitor along with two configurable active-low RESET outputs.
The MAX20484 significantly reduces system size and component count while improving reliability, as compared to separate ICs or discrete components. The MAX20484 meets ASIL D reliability when used with a supervisory controller. The device is designed to operate over the ambient temperature range of -40°C to +125°C.
Applications
- ADAS
 - Autonomous Driving Processing Systems
 - Power System Supervision and MCU/SoC Monitoring
 - Remote Sensor Modules
