MAX20478BATBA/VY+

Supervisors Overview

The MAX20478BATBA/VY+ is an ASIL-D qualified, 2-to-3 channel power system monitor designed for automotive applications. It operates within a supply voltage range of 2.35V to 5.50V and features multiple voltage monitoring inputs. The device integrates a windowed watchdog timer and one-time programmable (OTP) memory for configuration. It supports surface-mount installation in a TDFN-CU-10 package and functions reliably across an extended temperature range from -40°C to +125°C.

Supervisors Feature Summary

ASIL-D functional safety qualification for critical automotive power systems
Integrated windowed watchdog timer with configurable timeout
One-time programmable memory for flexible hardware configuration
Supports monitoring of two or three independent voltage rails

Supervisors Applications

Automotive battery management systems
Advanced driver-assistance systems (ADAS) power distribution
Vehicle infotainment power supervision
Electric vehicle control unit monitoring

Supervisors Procurement Notes

Verify the specific suffix VY+ against the official Analog Devices datasheet to confirm package type and temperature grade. Confirm ASIL-D compliance requirements match your system design. Check current availability status as automotive components may have restricted supply chains. Ensure ESD handling procedures are followed during SMD/SMT assembly.

Supervisors Selection Notes

Select this component when ASIL-D certification is mandatory for power monitoring circuits. Choose over lower-safety variants if system integrity requires strict fault detection. Consider the 2-to-3 channel flexibility for multi-rail architectures. Verify input voltage ranges align with the 2.35V to 5.50V operational specification.

Supervisors Part Context

Part of the MAX2047x family of automotive power monitors. Shares architectural similarities with the MAX20479AATBF/VY+. Designed specifically for high-reliability environments requiring ISO 26262 compliance. Differentiated by its specific pinout and OTP configuration options within the TDFN-CU-10 footprint.
