LTC2916ITS8-1#TRMPBF

Supervisors Overview

The LTC2916ITS8-1#TRMPBF is a voltage supervisor circuit manufactured by Analog Devices Inc. It features nine selectable threshold voltages and includes a manual reset input for controlled system recovery. The device operates within a supply voltage range of 1.2V to 12V and draws a typical quiescent current of 30µA. It provides an active-low or open-drain reset output with a fixed 200ms timeout period. The component is housed in an 8-pin TSOT-23 package and supports operation across an extended temperature range from -40°C to +125°C.

Supervisors Feature Summary

• Provides nine selectable voltage thresholds covering common logic levels
• Includes a dedicated manual reset input pin for user-controlled assertion
• Features low power consumption suitable for battery-operated applications
• Offers flexible reset output configuration via external resistor selection

Supervisors Applications

• Monitoring power rails in portable electronic devices
• Supervising voltage levels in automotive embedded systems
• Ensuring stable startup sequences in industrial control units
• Protecting microprocessor systems against brown-out conditions

Supervisors Procurement Notes

Verify the specific suffix TRMPBF indicates cut-tape packaging when sourcing samples or small quantities. Confirm the ITS8 designation corresponds to the industrial temperature grade (-40°C to +125°C) rather than the commercial or extended variants. Ensure compatibility with the 8-pin TSOT-23 footprint during PCB layout finalization. Cross-reference the datasheet revision date to confirm electrical characteristics match your design requirements.

Supervisors Selection Notes

Select this component when precise voltage monitoring with configurable thresholds is required alongside manual reset capability. The low quiescent current makes it suitable for energy-constrained designs compared to higher-power alternatives. Consider the TSOT-23 package size constraints relative to available board space. Evaluate the need for the manual reset feature versus automatic-only supervision options in the broader LTC2916 family.

Supervisors Part Context

This part belongs to the LTC2916 series of voltage supervisors, which are designed for monitoring single or multiple power supplies. The series offers various packages including DFN and TSOT-23, with options for different numbers of monitored channels and threshold configurations. The ITS8-1 variant specifically targets applications requiring manual reset intervention and industrial temperature stability.

Supervisors Replacement Considerations

LTC2916HTS8-1#TRMPBF: Higher temperature grade variant (up to 125°C). LTC2916IDDB-1#PBF: Different DFN-8 package form factor. LTC2911ITS8-1#TRMPBF: Three-channel monitor without manual reset input.
