MAX16036PLB31+

Supervisors Overview

The MAX16036PLB31+T is a voltage supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand, designed for battery backup applications. It operates within a supply voltage range of 0 V to 5.5 V and features a single monitored input. The device utilizes a 10-µDFN (2x2) surface-mount package and functions with an active-low reset output. It maintains operation across an extended industrial temperature range from -40°C to +85°C. Key electrical parameters include a typical quiescent current of 22 µA, a minimum reset timeout of 140 ms, and specific undervoltage and overvoltage thresholds associated with the '31' suffix designation.

Supervisors Feature Summary

• Provides reliable power monitoring for battery backup systems through dedicated undervoltage and overvoltage detection capabilities.
• Features an open-drain or open-collector active-low reset output to interface directly with microprocessor logic circuits.
• Integrates a fixed minimum reset timeout period to ensure stable system initialization upon power recovery.

Supervisors Applications

• Battery backup circuitry in portable electronic devices
• Microprocessor supervision in embedded control systems
• Voltage monitoring in industrial instrumentation

Supervisors Procurement Notes

Verify component authenticity as this part number is listed as obsolete by the manufacturer. Confirm that the specific '31' suffix corresponds to the required voltage threshold values for your design, as these are critical for proper supervision. Ensure compatibility with existing PCB footprints and validate thermal performance within the specified operating temperature range before finalizing procurement plans.

Supervisors Selection Notes

Select this component when a single-channel voltage supervisor with low quiescent current is required for battery-backed designs. The choice depends on matching the specific undervoltage and overvoltage trip points indicated by the suffix to the target system rails. Consider the 10-µDFN package size constraints and the need for an active-low reset signal compatible with the downstream processor inputs.

Supervisors Part Context

This component belongs to the MAX16036 series of voltage supervisors, which are optimized for low-power applications. The series offers various threshold options differentiated by alphanumeric suffixes. The PLB31 variant specifically denotes the voltage thresholds and packaging configuration within this family, sharing core architectural features with other members like the MAX16036LLB46+T.

Supervisors Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. As the component is marked obsolete, engineers must evaluate pin-compatible alternatives or redesign using currently active supervisory circuits from the same manufacturer or competitors.
