MAX16040PLA29+

Supervisors Overview

The MAX16040PLA29+ is a supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 2.7 V to 5.5 V and features a reset threshold voltage of 2.93 V. The device provides a low-active reset signal with a minimum reset timeout of 140 ms. It is housed in an 8-µDFN (2x2) package and supports surface mount installation. The component functions as a single-channel monitor suitable for backup battery circuits, operating reliably across a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Provides low-active reset output for system supervision
• Integrates internal timer for defined reset timeout duration
• Supports operation with external or internal reference voltages

Supervisors Applications

• Backup battery circuit monitoring
• Microprocessor reset supervision
• Portable electronic device power management

Supervisors Procurement Notes

Verify the specific suffix PLA29 against official datasheets to confirm the 2.93 V threshold and push-pull/totem pole output configuration. Confirm RoHS compliance status and check for obsolescence notices, as this part may be discontinued. Ensure the 8-µDFN footprint matches the target PCB design constraints before procurement.

Supervisors Selection Notes

Select this component when a precise 2.93 V threshold is required for voltage monitoring applications. The 8-µDFN package offers a compact solution for space-constrained designs. Verify that the 140 ms minimum timeout meets the system's startup requirements. Consider the low-power characteristics if battery life is a critical design parameter.

Supervisors Part Context

This part belongs to the MAX16033-MAX16040 family of low-power supervisory circuits from Maxim Integrated. These devices are designed to provide reliable reset signals for microprocessors and other digital logic. The family shares common architectural features but varies in threshold voltages and output configurations.

Supervisors Replacement Considerations

Check for direct pin-to-pin replacements within the MAX16040 series with different threshold suffixes. Verify compatibility with existing PCB layouts due to the 8-µDFN package dimensions.
