The MAX20481 is a complete ASIL-compliant SoC power system monitor with up to seven voltage-monitor inputs. Each input has factory OTP 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 for both refreshing and disabling the watchdog. The active-low RESET pin of the device can be set at the factory to assert under a variety of 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.
Applications
- Automotive ADAS Systems
- Autonomous Driving Processing Systems
