MAX16023PTAZ18+

Supervisors Overview

The MAX16023PTAZ18+ is a low-power battery-backup circuit manufactured by Analog Devices Inc./Maxim Integrated. It integrates a regulated 1.8V LDO capable of delivering up to 100mA output current, a microprocessor reset generator, and automatic VCC/BATT switchover logic. The device monitors a single voltage channel and operates within a temperature range of -40°C to +85°C (TA). It is housed in an 8-WDFN Exposed Pad package.

Supervisors Feature Summary

• Integrates a regulated 1.8V low-dropout regulator for stable backup power supply
• Provides automatic switchover between main supply (VCC) and battery (BATT)
• Includes a dedicated microprocessor reset generator for system reliability

Supervisors Applications

• Battery-backed memory systems requiring seamless power transition
• Portable electronic devices with limited power budgets
• Embedded systems needing reliable voltage supervision and reset signaling

Supervisors Procurement Notes

Verify the specific suffix 'Z18' corresponds to the 1.8V LDO output variant when sourcing. Confirm RoHS compliance status as indicated by the '+' suffix. Ensure the 8-WDFN exposed pad thermal requirements are met in the PCB layout design. Cross-reference the manufacturer's latest datasheet revision for any pinout or electrical characteristic updates before finalizing procurement.

Supervisors Selection Notes

Select this component when a combined solution for voltage monitoring, reset generation, and low-current backup regulation is required. The integrated 1.8V LDO makes it suitable for powering sensitive logic or memory during main power loss. Consider the 100mA current limit and the specific 1.8V output voltage against load requirements. The wide operating temperature range supports industrial applications.

Supervisors Part Context

This part belongs to the MAX16023/MAX16024 family of low-power battery-backup circuits. These devices are designed to manage power transitions in portable electronics. The MAX16023 variant specifically focuses on single-channel supervision with integrated regulation, distinguishing it from simpler supervisors that lack LDO capabilities.
