LTC1326CMS8#PBF

Supervisors Overview

The LTC1326CMS8#PBF is a supervisory circuit manufactured by Analog Devices Inc., designed for microprocessor precision monitoring. It features three independent voltage monitor inputs with threshold options of 3.3 V, 5 V, or adjustable settings. The device operates within a supply voltage range of 1 V to 7 V and consumes 40 uA of quiescent current. It provides active high, active low, and open drain output types with a fixed reset delay time of 200 ms. Accuracy is specified at 0.75%, and it includes power failure detection capabilities without manual reset or watchdog timer functions.

Supervisors Feature Summary

• Provides simultaneous monitoring of three distinct input voltages for system integrity
• Offers flexible output configurations including active high, active low, and open drain signals
• Integrates power failure detection to ensure reliable system supervision

Supervisors Applications

• Microprocessor precision monitoring systems
