MAX16056ATA23+T

Supervisors Overview

The MAX16056ATA23+T is a nano-power microprocessor supervisory circuit featuring a factory-trimmed reset threshold of 2.313V. It monitors input voltages ranging from 1.1V to 5V and provides an active-low push-pull reset output. The device includes a capacitor-adjustable reset timeout and an integrated watchdog timer with selectable timeout periods. Operating across a temperature range of -40°C to +125°C, it is housed in an 8-lead TDFN package with an exposed pad.

Supervisors Feature Summary

• Factory-trimmed reset threshold ensures precise voltage monitoring without external resistor dividers.
• Capacitor-adjustable reset timeout allows customization of the reset pulse width for specific system requirements.
• Integrated watchdog timer prevents software lockups by generating a reset if the input signal fails to toggle within the selected period.

Supervisors Applications

• Safety-critical automotive power-system supervision
• Embedded processing systems requiring robust voltage monitoring
• Internet of Things (IoT) edge computing devices

Supervisors Procurement Notes

Verify the exact suffix 'A23' confirms the 2.313V threshold. Confirm the '+T' indicates tape-and-reel packaging. Check current availability as distribution status may vary. Ensure the 8-TDFN package matches your PCB footprint. Validate RoHS compliance documentation for regulatory adherence.

Supervisors Selection Notes

Select this component when a fixed, accurate threshold near 2.3V is required for 1.1V to 5V rails. Choose the capacitor-adjustable timeout feature if system startup delays vary. The push-pull output drives loads directly without pull-up resistors. Consider the wide industrial temperature range for harsh environments.

Supervisors Part Context

This part belongs to the MAX1605x family of nano-power supervisors designed for low-voltage digital systems. Unlike adjustable variants using external resistors, the A23 suffix denotes a fixed internal reference. The series emphasizes minimal quiescent current and small footprint for portable and automotive electronics.

Supervisors Replacement Considerations

Cross-reference with other MAX1605x variants having similar thresholds. Verify pin compatibility for direct replacement. Ensure equivalent watchdog functionality and output drive strength match system needs.
