MAX20480 Four- to Seven-Input Automotive Power- System Monitor Family General Description Benefits and Features The MAX20480 is a complete ASIL-compliant SoC pow- Small Solution ersystem monitor with up to seven voltage monitor inputs. 2.35V to 5.50V Operating Supply Voltage Each input has programmable OV/UV thresholds of be- Only One External Component Required tween 2.5% and 10% with 1% accuracy. Two of the in- 150A Operating Current puts have a separate remote ground-sense input and sup- 8A Power-Down Mode 2 port DVS through the integrated I C interface. High Precision The MAX20480 contains a programmable flexible power Selectable 102.5% to 110% OV Monitors sequence recorder (FPSR). This recorder stores power-up Selectable 97.5% to 90% UV Monitors and power-down timestamps separately, and supports on/ 1% Accuracy off and sleep/standby power sequences. The MAX20480 0.5% Step Size also contains a programmable challenge/response watch- ASIL-D Compliance 2 dog, which is accessible through the I C interface, along Highly Integrated with a configurable RESET output. Five Fixed-Voltage Monitoring Inputs The MAX20480 improves reliability while significantly re- Two Differential DVS Tracking-Voltage Monitoring ducing system size and component count, compared to Inputs with Remote-Ground Sense separate ICs or discrete components. The MAX20480 Power-Sequencing Recording meets ASIL-D reliability when used with a supervisory Simple or Challenge/Response Windowed controller. The device is designed to operate over the am- Watchdog bient temperature range of -40C to +125C.
