MAX16023LTAT18+T

Supervisors Overview

The MAX16023LTAT18+T is a single-channel battery backup supervisor circuit manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 1.7V to 5.5V and features an adjustable threshold with a typical value of 3.08V for the LT suffix variant. The device provides a low-active push-pull output and includes a minimum reset timeout of 145ms. Designed for surface mount installation, it utilizes an 8-TDFN (3x3) package with an exposed pad. The component supports operation across an extended temperature range from -40°C to +85°C and complies with RoHS3 standards.

Supervisors Feature Summary

• Monitors system voltage levels to detect power failures or fluctuations
• Generates a reset signal upon detection of undervoltage conditions
• Supports battery backup switching applications

Supervisors Applications

• Portable electronic devices requiring power failure detection
• Battery-powered systems needing backup circuit supervision
• Embedded systems monitoring critical voltage rails

Supervisors Procurement Notes

Verify the specific suffix 'LT' against the design requirement, as it indicates a fixed threshold voltage rather than an adjustable one. Confirm the 8-TDFN package dimensions match the PCB footprint. Ensure the operating temperature range meets the environmental specifications of the final assembly. Cross-reference the manufacturer part number with official Analog Devices documentation to confirm current production status and compliance certifications.

Supervisors Selection Notes

Select this component when a dedicated supervisor for battery backup circuits is required. The fixed threshold simplifies design compared to adjustable variants. Consider the 8-pin TDFN package for space-constrained layouts. Evaluate the reset timeout duration to ensure compatibility with system startup requirements. Verify that the input voltage range covers the expected battery discharge profile.

Supervisors Part Context

This part belongs to the MAX16023/MAX16024 family of supervisory circuits designed for portable electronics. It serves as a voltage monitor that triggers a reset or alert when the supply voltage drops below a set level. The family offers various packages and threshold options to accommodate different system architectures and power management strategies in compact form factors.

Supervisors Replacement Considerations

Check for MAX16023LTAT18+ without the trailing 'T' if tape-and-reel packaging is not required. Verify functional equivalents from other manufacturers only if pinout and electrical characteristics are identical.
