MAX16089XS46L+T

Supervisors Overview

The MAX16089XS46L+T is a low-power microprocessor supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 1.2V to 5.5V and features a fixed reset threshold voltage of 4.63V. The device provides a single active-low reset output with an open-drain or open-collector configuration, housed in a compact SC-70-4 surface-mount package. It includes a programmable reset timeout period ranging from 50ms to 1.4s and supports manual reset functionality via an external input pin.

Supervisors Feature Summary

• Ultra-low quiescent current consumption for extended battery life in portable applications
• Integrated watchdog timer with selectable timeout periods for system reliability
• Manual reset input capability allowing external control over the reset state
• Wide operating supply voltage range suitable for various logic families

Supervisors Applications

• Portable consumer electronics requiring low power monitoring
• Battery-operated embedded systems needing reliable voltage supervision
• Industrial control units utilizing microprocessors or DSPs
• Automotive infotainment and instrumentation modules

Supervisors Procurement Notes

Verify component authenticity through authorized distributors due to limited availability status. Confirm RoHS compliance and lead times directly with the manufacturer or certified suppliers. Ensure storage conditions meet moisture sensitivity level requirements before assembly. Cross-reference part numbers carefully as suffixes indicate specific threshold voltages and packaging options.

Supervisors Selection Notes

Select this component when a fixed 4.63V threshold is required for system supervision. Consider the SC-70-4 package size constraints against available board space. Evaluate the need for manual reset inputs and watchdog timer integration versus simpler supervisor alternatives. Compare quiescent current specifications against other devices in the MAX16089 family if lower power is critical.

Supervisors Part Context

This device belongs to the MAX16089 series of ultra-versatile, low-power microprocessor supervisory circuits. It complements other Maxim Integrated PMIC solutions by providing essential voltage monitoring and reset generation functions. The series is designed to support complex digital systems requiring robust power management and fault detection capabilities.

Supervisors Replacement Considerations

Check for MAX16089 variants with different threshold voltages (e.g., XS30H/V) if the 4.63V setting does not match the target rail. Verify pin compatibility with existing PCB layouts when substituting with other SC-70-4 supervisors.
