MAX6364PUT26+

Overview

The MAX6364PUT26+ is a low-power microprocessor supervisory circuit from Analog Devices/Maxim Integrated. It integrates power supply monitoring and battery backup management in a single SOT23 package. The device features a fixed reset threshold voltage of 2.63V, ensuring reliable system resets when the supply voltage drops below this level. It includes a manual reset input for external control and provides a watchdog timer to prevent software lockups. The component operates with a supply current of typically 10µA, making it suitable for battery-powered applications.

Feature Summary

• Integrates voltage monitoring and battery backup control functions
• Provides fixed reset threshold at 2.63V for reliable supervision
• Includes manual reset input for external system control
• Features built-in watchdog timer to prevent processor lockups

Applications

• Microprocessor system power monitoring
• Battery-backed embedded systems
• Portable electronic devices requiring low standby current
• Industrial control units needing watchdog protection

Procurement Notes

Verify the exact suffix 'PUT26+' matches the required 2.63V threshold. Confirm package type is SOT23-6. Check for RoHS compliance (+ suffix). Ensure availability status as distribution may vary. Validate pinout compatibility with existing PCB layout before ordering.

Selection Notes

Select this part when a fixed 2.63V reset threshold is required. Choose over discrete solutions to reduce component count and board space. Consider the low 10µA supply current for battery life optimization. Verify that the SOT23-6 package fits the mechanical constraints. Ensure the manual reset input functionality meets system design requirements.

Part Context

Part of the MAX6364 family of microprocessor supervisors. Designed to replace multiple discrete components including voltage detectors, battery switches, and watchdog timers. Offers a compact alternative to traditional power management architectures in space-constrained designs.

Replacement Considerations

Check MAX6364PUT23+ for 2.325V threshold variant. Verify MAX6364PUT29+ for 2.93V threshold option. Ensure functional equivalence in reset timing and watchdog behavior. Confirm package and pinout compatibility for direct replacement.
