LTC2911CDDB-2

Supervisors Overview

The LTC2911CDDB-2 is a multi-supply voltage monitor manufactured by Analog Devices Inc. It features three monitored inputs with threshold voltages of 2.5 V, 3.3 V, and an adjustable setting. The device provides an open-drain output type and includes a fixed reset delay time of 200 ms. It does not support manual reset or watchdog timer functions. The component operates within a maximum supply voltage of 6.5 V and is housed in an SOT-23-8 package for surface mount installation.

Supervisors Feature Summary

• Monitors up to three independent voltage rails simultaneously
• Provides configurable threshold detection including adjustable settings
• Generates system reset signals via open-drain output interface

Supervisors Applications

• Multi-rail power supply supervision in embedded systems
• Voltage monitoring for microprocessor and FPGA boards
• Industrial control unit power integrity verification

Supervisors Procurement Notes

Verify the specific suffix designation against official Analog Devices documentation to confirm pinout and electrical characteristics. Ensure the selected variant matches the required threshold configuration and package style for your PCB layout. Cross-reference the manufacturer part number with authorized distributors to confirm current availability status and lead times before finalizing procurement plans.

Supervisors Selection Notes

Select this component when simultaneous monitoring of multiple voltage rails is required without manual reset functionality. Consider the open-drain output compatibility with your system logic levels. Evaluate the 200 ms reset delay against your system startup requirements. Verify that the operating temperature range meets your environmental specifications.

Supervisors Part Context

This part belongs to the LTC2911 series of supervisory circuits designed for low-voltage applications. It serves as a critical component for ensuring system stability by detecting out-of-range voltage conditions across multiple power domains. The series offers various threshold combinations to accommodate different standard voltage rails commonly found in digital electronics.

Supervisors Replacement Considerations

Consult Analog Devices documentation for verified cross-references. Alternative parts may include other members of the LTC2911 family with different threshold configurations or package options. Ensure any substitute maintains compatible output drive capabilities and reset timing characteristics.
