LTC2935CTS8-3#TRMPBF

Supervisors Overview

The LTC2935CTS8-3#TRMPBF is an ultra-low power supervisory circuit manufactured by Analog Devices Inc. It operates within a supply voltage range of 1.6 V to 5.5 V and features selectable threshold voltages, specifically including 1.6 V, 1.72 V, 1.84 V, 1.96 V, 2.08 V, 2.2 V, 2.32 V, and 2.44 V for the '-3' suffix variant. The device provides an open-drain output with active-low reset functionality and includes manual reset capability. It consumes only 500 nA of quiescent current and offers a minimum reset timeout of 140 ms. The component is housed in an 8-pin TSOT-23 package and is rated for commercial temperature operation from 0°C to +70°C.

Supervisors Feature Summary

• Ultra-low power consumption with 500 nA operating current
• Selectable voltage thresholds for precise monitoring
• Manual reset input for system control
• Open-drain active-low reset output

Supervisors Applications

• Portable battery-powered equipment requiring low standby current
• Embedded systems needing reliable voltage supervision
• Industrial control units with strict power constraints

Supervisors Procurement Notes

Verify the specific threshold voltage combination corresponding to the '-3' suffix against the official datasheet before procurement. Confirm that the TSOT-23-8 package and commercial temperature range meet the design requirements. Ensure compatibility with the target system's logic levels and reset timing specifications.

Supervisors Selection Notes

Select this component when ultra-low quiescent current is critical for extending battery life in portable devices. The selectable threshold feature allows customization for various rail voltages without changing the base part number. Consider the open-drain output requirement for pull-up resistor implementation in the final circuit design.

Supervisors Part Context

This part belongs to the LTC2935 family of supervisory circuits designed for low-power applications. It shares core functionalities with other variants like the LTC2935ITS8-3 and LTC2935CDC-3, differing primarily in package type (TSOT-23 vs. DFN) and temperature grade. The '#TRMPBF' suffix indicates tape-and-reel packaging with lead-free compliance.
