MAX20480DATEB/VY+

Supervisors Overview

The MAX20480DATEB/VY+ is a seven-input automotive power-system monitor designed for supervising system-on-chip (SoC) power rails in advanced driver-assistance systems. It operates with a supply voltage range of 2.35V to 5.5V and features a 32ms delay timer. The device utilizes an open-drain reset output and is housed in a TQFN-EP-16 package.

Supervisors Feature Summary

• Monitors up to seven independent input voltages for comprehensive power system supervision
• Includes dual undervoltage lockout mechanisms to ensure stable operation during low supply conditions
• Features a programmable delay timer for controlled reset assertion timing

Supervisors Applications

• System-on-Chip (SoC) power monitoring in automotive environments
• Advanced Driver-Assistance Systems (ADAS) power supervision
• Microcontroller unit (MCU) power rail monitoring

Supervisors Procurement Notes

Verify the specific suffix 'DATEB' against the manufacturer's current datasheet to confirm pinout and electrical characteristics, as suffixes often denote specific tape-and-reel packaging or temperature grades. Ensure compatibility with your board layout regarding the exposed pad thermal connection on the TQFN-EP-16 package.

Supervisors Selection Notes

Select this component when monitoring multiple power rails within a single automotive application. It is suitable for designs requiring integrated supervision of SoC and MCU supplies without needing separate monitors for each rail. Verify that the required number of monitored inputs does not exceed the seven available channels.

Supervisors Part Context

This part belongs to the MAX204xx family of automotive power-system monitors from Analog Devices/Maxim Integrated. These devices are engineered to provide reliable supervision for complex electronic architectures in vehicles, ensuring safety and functionality by detecting abnormal voltage conditions across critical power domains.

Supervisors Replacement Considerations

Check for other members of the MAX204xx family with fewer input channels if all seven are not required. Verify equivalent packages such as TQFN-EP-16 from other manufacturers if sourcing constraints exist, ensuring pin compatibility and electrical specifications match.
