MAX20480BATEJ/VY+T

Supervisors Overview

The MAX20480BATEJ/VY+T is a seven-channel automotive system monitor manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates within an extended temperature range of -40°C to +125°C and holds AEC-Q100 qualification for automotive reliability. The device features seven independently monitored voltage inputs with selectable threshold combinations. It provides open-drain or open-collector outputs and includes a reset timeout of at least 28.8ms. The component is housed in a compact 16-SW-TQFN (3x3) package designed for surface-mount assembly with wettable flanks.

Supervisors Feature Summary

• Seven independent voltage monitoring channels with configurable threshold options
• Automotive-grade qualification compliant with AEC-Q100 standards
• Open-drain or open-collector output configuration for flexible interfacing
• Extended operating temperature range suitable for harsh environments

Supervisors Applications

• Automotive electronic control units
• Multi-rail power distribution systems
• Safety-critical vehicle subsystems
• Industrial monitoring applications requiring high reliability

Supervisors Procurement Notes

Verify the specific suffix BATEJ against official datasheets to confirm exact threshold configurations and package variants. Ensure compatibility with existing board layouts regarding the 16-SW-TQFN footprint. Confirm AEC-Q100 certification requirements are met for the target automotive application. Check for any specific ordering restrictions or limited availability status from authorized distributors before finalizing procurement plans.

Supervisors Selection Notes

Select this component when designing systems requiring simultaneous monitoring of multiple voltage rails in automotive environments. The seven-channel capacity reduces bill-of-materials count compared to single-channel monitors. Consider the open-drain output capability for wired-OR logic implementations. Verify that the 28.8ms minimum reset timeout aligns with system startup timing requirements. Evaluate the 3x3mm package size constraints against available PCB real estate.

Supervisors Part Context

This part belongs to the MAX20480 family of system supervisors designed for complex embedded systems. It complements other Maxim Integrated PMIC solutions by providing comprehensive fault detection without requiring external comparators. The series supports various automotive protocols and interfaces, ensuring seamless integration into modern vehicle architectures while maintaining strict compliance with industry safety and quality standards.

Supervisors Replacement Considerations

Check for pin-compatible alternatives within the MAX20480 series offering different channel counts or threshold sets. Verify that substitute components maintain identical AEC-Q100 ratings and thermal specifications. Ensure replacement packages match the 16-SW-TQFN dimensions and wettable flank requirements for automated assembly compatibility.
