LTC2911CTS8-4

Supervisors Overview

The LTC2911CTS8-4 is a precision, low-power voltage supervisor from Analog Devices Inc. designed to monitor a single supply rail with a fixed reset threshold of 4.375V. It operates within a supply voltage range of 1.62V to 5.5V and features a push-pull active-low reset output. The device incorporates an internal timer that delays the assertion of the reset signal for 200ms upon power-up or fault detection, ensuring stable system initialization. It includes manual reset functionality via an external pin and offers configurable watchdog timeout options.

Supervisors Feature Summary

• Provides precise monitoring of a single power supply rail with a fixed threshold voltage
• Includes an internal delay timer to prevent false resets during power transitions
• Features a manual reset input allowing external control over the reset state
• Delivers a push-pull active-low reset output compatible with various logic families

Supervisors Applications

• Microprocessor and microcontroller power supply supervision
• Battery-powered systems requiring reliable power management
• Industrial control systems needing watchdog functionality
• Portable electronic devices with strict power sequencing requirements

Supervisors Procurement Notes

Verify the specific suffix 'S8-4' against official Analog Devices documentation to confirm package type and temperature grade. Ensure compatibility with your system's voltage levels and reset timing requirements before procurement. Cross-reference part numbers with authorized distributors to avoid counterfeit components.

Supervisors Selection Notes

Select this component when a fixed 4.375V threshold is required for power monitoring. Consider the 200ms delay feature if your system requires extended stabilization time after power application. Evaluate the manual reset capability if external reset control is necessary for your design.

Supervisors Part Context

The LTC2911 series belongs to Analog Devices' family of voltage supervisors and power sequencers. These devices are engineered for high reliability in embedded applications. The LTS8-4 variant specifically denotes the SOT-23-8 package configuration with defined electrical characteristics suitable for space-constrained designs.

Supervisors Replacement Considerations

Consult Analog Devices official substitution guides for equivalent parts. Verify that any alternative maintains the same 4.375V threshold and 200ms delay characteristics. Ensure pinout compatibility and package dimensions match your existing PCB layout.
