MAX16034LLB31+

Supervisors Overview

The MAX16034LLB31+ is a supervisory integrated circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand, housed in a 10-WFDFN surface-mount package. It functions as a battery backup circuit designed to monitor a single voltage rail. The device features an active-low reset output with a push-pull, totem-pole configuration. Key electrical characteristics include an operating supply current of 22 µA and a power dissipation rating of 402.8 mW. The component includes a watchdog timer input for system reliability.

Supervisors Feature Summary

• Integrates a watchdog timer input for enhanced system monitoring and fault detection capabilities.
• Provides a dedicated battery-on output function to indicate battery status within the monitored circuit.
• Features an active-low reset signal with a push-pull output stage for robust digital interface compatibility.

Supervisors Applications

• Motor control applications requiring stable system response
• Embedded communication systems needing reliable supervision
• Battery backup circuits in portable electronic devices

Supervisors Procurement Notes

Verify the specific suffix '31' against the manufacturer's official datasheet to confirm pinout and functional variations. Ensure the 10-WFDFN package dimensions match your PCB footprint requirements. Confirm that the active-low reset polarity aligns with your microcontroller's input specifications before finalizing procurement orders.

Supervisors Selection Notes

Select this component when a single-voltage supervisor with integrated watchdog functionality is required. The low 22 µA supply current makes it suitable for battery-powered designs. Ensure the application environment supports the 402.8 mW power dissipation limit. Verify compatibility with the target system's voltage levels and reset timing requirements.

Supervisors Part Context

This part belongs to the MAX1603x family of supervisory circuits from Maxim Integrated. The family offers various configurations including manual-reset, watchdog timer, and battery-on outputs. The LLB31 variant specifically integrates the watchdog timer feature within the 10-pin WDFN package, distinguishing it from other family members like the MAX16033 or MAX16035.

Supervisors Replacement Considerations

The MAX16034LLB29+ is a documented alternative within the same series. Both share identical operating supply currents of 22 µA. Verify if the specific reset timeout or pinout differences between the LLB29 and LLB31 suffixes impact your design before substitution.
