LTC2911ITS8-1

Supervisors Overview

The LTC2911ITS8-1 is a multi-voltage supervisor IC from Analog Devices Inc., housed in an 8-pin TSOT-23 package. It monitors three distinct voltage rails with fixed thresholds of 3.086V and 4.675V, plus one adjustable channel. The device features a push-pull output, active-low reset signal, and selectable timeout duration. It operates within a supply voltage range of 2.7V to 5.5V and supports temperatures from -40°C to +85°C.

Supervisors Feature Summary

• Monitors three independent voltage channels simultaneously
• Provides active-low reset signal with push-pull output drive
• Includes selectable timeout duration for reset assertion
• Supports adjustable voltage threshold on one monitoring channel

Supervisors Applications

• Multi-rail power system supervision
• Embedded system voltage monitoring
• Industrial control board protection

Supervisors Procurement Notes

Verify the complete part number including suffixes such as #TRMPBF against official Analog Devices documentation to ensure correct packaging and temperature grade. Confirm RoHS compliance status and moisture sensitivity level requirements prior to ordering. Cross-reference datasheet specifications with design constraints to validate performance under operating conditions.

Supervisors Selection Notes

Select this component when simultaneous monitoring of three voltages is required in a compact surface-mount package. Ensure the fixed thresholds of 3.086V and 4.675V align with target rail levels. Verify that the adjustable channel meets the remaining monitoring needs. Check compatibility with system logic levels due to the push-pull output configuration.

Supervisors Part Context

Part of the LTC2911 family of precision supervisors. Shares core architecture with variants offering different threshold combinations or packages. Designed for applications requiring reliable power management without complex external components. Integrates essential supervision functions into a small form factor suitable for space-constrained designs.

Supervisors Replacement Considerations

LTC2911ITS8-2#TRMPBF offers alternative fixed thresholds. LTC2911HTS8-1#TRMPBF provides higher temperature rating options. Verify electrical parameters and pinout compatibility before substitution.
