MAX6422XS16+T

Supervisors Overview

The MAX6422XS16+T is a low-power supervisor circuit designed for embedded microprocessor applications. It monitors a single voltage supply with a fixed threshold of 1.575V. The device features a capacitor-adjustable reset timeout delay, allowing customization of the reset pulse width. It utilizes a push-pull, totem pole output configuration and operates within an ambient temperature range of -40°C to +125°C. Packaged in a compact SC-70-4 (SOT-343) case, it supports lead-free assembly.

Supervisors Feature Summary

• Capacitor-adjustable reset timeout delay for flexible timing control
• Push-pull totem pole output driver for robust signal integrity
• Fixed voltage monitoring threshold at 1.575V
• Extended industrial operating temperature range

Supervisors Applications

• Embedded microprocessor power supply supervision
• Edge computing system reset circuits
• Battery-powered device voltage monitoring

Supervisors Procurement Notes

Verify the exact suffix 'XS16' corresponds to the 1.575V threshold and SC-70-4 package variant. Confirm lead-free status (+ symbol) matches environmental compliance requirements. Ensure the open-drain/open-collector vs. push-pull specification aligns with the specific datasheet revision, as some sources indicate configurable outputs while others specify push-pull. Validate manufacturer source as Analog Devices Inc./Maxim Integrated.

Supervisors Selection Notes

Select this component when a fixed 1.575V monitoring threshold is required. The adjustable timeout via external capacitor offers design flexibility compared to fixed-delay supervisors. Consider the SC-70-4 footprint for space-constrained layouts. Verify compatibility with the target microprocessor's reset input requirements regarding the push-pull output drive capability.

Supervisors Part Context

This part belongs to the MAX642x series of low-power reset circuits from Maxim Integrated. These devices are engineered for reliable operation in digital systems requiring precise voltage supervision. The series typically includes variants with different thresholds and output configurations, serving as critical components for system stability during power-up and brown-out events.

Supervisors Replacement Considerations

Check for direct pin-compatible alternatives within the MAX642x family with matching 1.575V thresholds. Verify that any substitute maintains the same SC-70-4 package and push-pull output characteristics. Ensure thermal performance and operating temperature ranges meet or exceed the original specifications.
