LTC2935CTS8-4#TRMPBF

Supervisors Overview

The LTC2935CTS8-4#TRMPBF is an ultra-low power voltage supervisory circuit manufactured by Analog Devices Inc. It monitors a single input voltage and provides a reset output with selectable threshold voltages, specifically configured for the -4 suffix to detect levels of 1.6 V, 1.72 V, 1.84 V, 1.96 V, 2.08 V, 2.2 V, 2.32 V, or 2.44 V. The device features a manual reset function, a 200 ms reset delay time, and operates within a supply voltage range up to 5.5 V. It offers active high, active low, and push-pull output types with 1.5% accuracy. Designed for surface mount installation in an SOT-23-8 package, it functions between 0°C and +70°C while consuming only 500 nA of quiescent current.

Supervisors Feature Summary

• Ultra-low power consumption suitable for battery-operated systems
• Configurable power-fail detection with selectable threshold options
• Manual reset capability for system control flexibility

Supervisors Applications

• Portable electronic devices requiring extended battery life

Supervisors Procurement Notes

Verify the specific suffix configuration against design requirements to ensure correct threshold selection. Confirm package compatibility and thermal management needs for the SOT-23-8 footprint. Check regional availability as distribution status may vary. Ensure compliance with RoHS standards if required by your manufacturing process. Validate operating temperature ranges against your application environment.

Supervisors Selection Notes

Select this component when ultra-low quiescent current is critical for system efficiency. Choose based on the required threshold voltage combination provided by the -4 suffix. Consider the SOT-23-8 package size constraints and manual reset functionality needs. Evaluate the 1.5% accuracy specification against system tolerance requirements. Compare with other supervisors if higher voltage monitoring or different output configurations are needed.

Supervisors Part Context

This part belongs to the LTC2935 series of voltage supervisors from Analog Devices. It is designed for applications where power conservation is paramount.
