LTC2935ITS8-1#TRPBF

Supervisors Overview

The LTC2935ITS8-1#TRPBF is an ultra-low power voltage supervisor from Analog Devices, housed in a compact SOT-23-8 package. It features selectable threshold voltages including 2.25 V, 2.4 V, 2.55 V, 2.7 V, 2.85 V, 3 V, 3.15 V, and 3.3 V to accommodate various system requirements. The device provides a manual reset function with a fixed 200 ms reset delay time and operates within a supply voltage range up to 5.5 V. It draws only 500 nA of operating current and maintains accuracy within 1.5%. Designed for surface mount installation, it functions reliably across a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Ultra-low power consumption with 500 nA operating current
• Selectable threshold voltage combinations for flexible monitoring
• Manual reset capability with defined 200 ms delay
• High accuracy of 1.5% for precise supervision

Supervisors Applications

• Portable battery-powered equipment requiring extended life
• Embedded systems needing reliable power-fail detection
• Microcontroller reset circuits in industrial environments

Supervisors Procurement Notes

Verify the specific suffix TRPBF indicates tape-and-reel packaging when sourcing. Confirm the ITS8 designation matches the required SOT-23-8 thin outline package for your PCB layout. Ensure the selected threshold combination aligns with your target voltage rail. Check current availability status as distribution may vary by region.

Supervisors Selection Notes

Choose this component when low quiescent current is critical for battery efficiency. The selectable thresholds allow optimization without external resistors. Verify that the 200 ms delay meets your system startup timing requirements. Ensure the 5.5 V maximum rating covers your highest expected input voltage.

Supervisors Part Context

This part belongs to the LTC2935 series of supervisors designed for low-power applications. It complements other variants like the LTC2934 which offers adjustable thresholds but fewer inputs. The family focuses on providing robust supervision in minimal footprint packages suitable for space-constrained designs.
