MAX16023LTAS18+T

Supervisors Overview

The MAX16023LTAS18+T is a battery management integrated circuit designed for backup applications. It features an internal 1.8V reference and supports external programming of the backup threshold voltage via a resistor divider. The device monitors supply voltage and automatically switches to a connected backup battery when the main supply drops below the set threshold. It includes a manual reset pin for system control and operates within a specified temperature range suitable for industrial environments.

Supervisors Feature Summary

• Automatic switching between main power and backup battery based on programmable voltage thresholds
• Integrated manual reset functionality for controlled system recovery
• Supports external programming of backup activation levels using standard resistors

Supervisors Applications

• Non-volatile memory backup systems
• Real-time clock power management
• Embedded controller power supervision

Supervisors Procurement Notes

Verify the specific suffix LTAS18 against official Analog Devices documentation to confirm the 1.8V reference configuration. Confirm package availability and lead times directly with authorized distributors as stock levels fluctuate. Ensure the selected variant matches the required thermal performance for the intended operating environment.

Supervisors Selection Notes

Select this component when a fixed 1.8V reference is required for the backup threshold calculation. Compare against other MAX16023 variants with different fixed references or adjustable options if the design requires flexibility in setting the trip point without changing external resistor values. Verify compatibility with the target system's voltage rails.

Supervisors Part Context

This part belongs to the MAX16023 family of battery backup controllers manufactured by Analog Devices (Maxim Integrated). These devices are commonly used in portable electronics and industrial equipment to preserve data during power outages. The LTAS18 suffix indicates a specific version with a 1.8V internal reference, distinguishing it from other variants like the LTA33 or LTA50.

Supervisors Replacement Considerations

Direct replacements include other MAX16023 variants such as MAX16023LTAL33+T or MAX16023LTAL50+T if the reference voltage difference is acceptable. Cross-reference with similar battery backup supervisors from other manufacturers only after verifying pinout and electrical parameter compatibility.
