LTC2911CTS8-3#TRPBF

Supervisors Overview

The LTC2911CTS8-3#TRPBF is a precision supervisory circuit manufactured by Analog Devices Inc., designed to monitor three independent voltage rails. It operates within a supply voltage range of 1.7V to 5.5V and draws a typical quiescent current of 10µA. The device features adjustable reset thresholds with an accuracy of 1% and includes a power-fail comparator for system protection. It provides a push-pull reset output and supports selectable or adjustable reset timeout delays. Packaged in an 8-lead TSOT-23, it functions reliably across an industrial temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Monitors three independent voltage inputs simultaneously
• Includes a dedicated power-fail comparator
• Features adjustable reset threshold voltages
• Supports selectable or adjustable reset timeout delays

Supervisors Applications

• Multi-rail power supply monitoring in embedded systems
• Industrial control unit supervision
• Telecommunications equipment power management
• Portable electronic devices requiring low standby current

Supervisors Procurement Notes

Verify the specific suffix 'CTS8-3' against official Analog Devices documentation to confirm pinout compatibility and threshold settings. Confirm RoHS compliance status via the manufacturer's datasheet before integration. Ensure the operating temperature range meets your application requirements. Cross-reference the package type TSOT-23-8 with your PCB footprint design. Validate availability through authorized distributors as supply may be limited.

Supervisors Selection Notes

Select this component when simultaneous monitoring of three distinct voltage rails is required alongside power-fail detection. The low 10µA quiescent current makes it suitable for battery-operated applications. Choose this part if adjustable reset thresholds are needed rather than fixed values. Ensure the TSOT-23-8 package fits your board space constraints. Verify that the push-pull output drive capability matches your downstream logic requirements.
