MAX16038LLA23+

Supervisors Overview

The MAX16038LLA23+ is a voltage supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It operates within an input voltage range of 1.7V to 5.5V and features a fixed threshold voltage of 2.3V. The device provides an active-low, open-drain reset output with a typical reset delay time of 280ms. It consumes a maximum supply current of 22µA and functions reliably across an industrial temperature range from -40°C to +85°C. The component is housed in an 8-pin UDFN package.

Supervisors Feature Summary

• Monitors single power supply rail for under-voltage conditions
• Provides active-low open-drain reset signal assertion
• Supports battery backup switching functionality
• Operates with low quiescent current consumption

Supervisors Applications

• Portable electronic devices requiring power supervision
• Battery-powered systems with backup power management
• Embedded controllers needing voltage monitoring
• Industrial equipment operating in wide temperature ranges

Supervisors Procurement Notes

Verify the specific suffix 'LLA23' matches the required 2.3V threshold voltage during procurement. Confirm the UDFN-8 package dimensions align with PCB layout constraints. Ensure compatibility with the target system's voltage levels and temperature requirements before ordering.

Supervisors Selection Notes

Select this component when a fixed 2.3V threshold is required for power monitoring. Consider the 22µA supply current for battery life optimization. Verify that the open-drain output configuration suits the downstream logic interface. Check availability as distribution status may vary.

Supervisors Part Context

This part belongs to the MAX16039/MAX16038 series of low-power voltage supervisors. These components are designed for applications requiring reliable power management in small form factors. The series offers various threshold options to accommodate different system voltage rails.

Supervisors Replacement Considerations

Check for direct pin-compatible alternatives within the same series offering different threshold voltages if the 2.3V setting is not suitable. Verify electrical specifications match exactly before substituting.
