MAX16038LLA46+T

Supervisors Overview

The MAX16038LLA46+T is a battery backup supervisor IC manufactured by Analog Devices Inc. (Maxim Integrated). It operates with a low supply voltage of 1.2V and provides precision monitoring for power-supply voltages including 5.0V, 3.3V, 3.0V, and 2.5V. The device features an independent power-fail comparator and a push-pull/totem pole output. Key electrical parameters include a threshold voltage of 4.63V, active-low reset functionality, and a minimum reset timeout of 140ms. It supports an operating temperature range from -40°C to 85°C and is housed in an 8-µDFN (2x2) package.

Supervisors Feature Summary

• Low 1.2V operating supply voltage capability
• Precision monitoring of standard power-supply rails
• Independent power-fail comparator for system integrity

Supervisors Applications

• Battery backup systems requiring voltage supervision
• Embedded systems monitoring 3.3V or 5.0V logic supplies
• Industrial control units operating in extended temperature ranges

Supervisors Procurement Notes

Verify the exact suffix against official Analog Devices documentation to confirm pinout and functional compatibility. Confirm RoHS3 compliance status as specified in current datasheets. Ensure the 8-UDFN package dimensions match your PCB footprint requirements before finalizing procurement orders.

Supervisors Selection Notes

Select this component when a low-voltage supervisor is required for critical power-rail monitoring. The integrated power-fail comparator allows for early warning detection separate from the reset signal. Consider the 140ms minimum timeout duration to ensure stable system initialization under varying load conditions.

Supervisors Part Context

This part belongs to the Maxim Integrated line of power management ICs, now under Analog Devices. It serves as a dedicated supervisor for maintaining system stability during power transitions. The device is designed to replace older discrete solutions with a single, compact integrated circuit for reliable voltage monitoring.

Supervisors Replacement Considerations

Check for direct cross-references within the Analog Devices portfolio. Verify that any substitute maintains the 4.63V threshold and 8-UDFN package form factor. Ensure compatible reset timeout characteristics to avoid system instability during power-up sequences.
