LTC2913HMS-2#TRPBF

Supervisors Overview

The LTC2913HMS-2#TRPBF is a dual input voltage monitor from Analog Devices, designed for supervising multiple voltages in various applications. It features two independent inputs per monitored voltage, allowing for the monitoring of two distinct signals simultaneously. The device provides an active low reset output and operates within automotive temperature ranges. Packaged in a 10-pin MSOP, it supports threshold voltages such as 3.3V and 5V, ensuring reliable system supervision for critical power rails.

Supervisors Feature Summary

• Dual input capability allows simultaneous monitoring of two separate voltage signals for enhanced redundancy or differential checking.
• Provides an active low reset output to signal under-voltage conditions or fault states to the system processor.
• Designed for automotive environments with specified operating temperature ranges suitable for harsh conditions.

Supervisors Applications

• Supervising multiple power rails in automotive electronic control units (ECUs)
• Monitoring redundant voltage sources in safety-critical industrial systems
• System reset generation in embedded controllers requiring dual-input validation

Supervisors Procurement Notes

Verify component authenticity through authorized distributors due to limited supply status. Confirm package integrity upon receipt as MSOP packages are sensitive to moisture. Check datasheet revisions for any updates to electrical characteristics or pin configurations before finalizing design integration.

Supervisors Selection Notes

Select this part when dual independent voltage monitoring is required within a single supervisor IC. Ensure the application demands active low reset signaling and fits within the automotive temperature range. Verify that the input voltage levels align with the supported thresholds and that the MSOP package size meets board space constraints.

Supervisors Part Context

This component belongs to the LTC2913 series of multi-voltage supervisors. It complements other Analog Devices PMICs by providing dedicated voltage monitoring functionality. The series is optimized for applications requiring high reliability and precise voltage tracking across multiple rails without external comparator components.

Supervisors Replacement Considerations

Check for direct pin-compatible alternatives within the LTC291x family. Verify if single-input monitors suffice if dual-channel capability is not strictly required. Consider newer generations of voltage supervisors with integrated watchdog features if system complexity increases.

Supervisors FAQ

What is the function of the dual inputs on the LTC2913?

The dual inputs allow the device to monitor two separate voltage signals independently, enabling comparison or redundant monitoring of critical power rails.

Is the reset output active high or active low?

The LTC2913HMS-2#TRPBF features an active low reset output, which asserts when the monitored voltage falls below the set threshold.
