LTC1921CMS8#TRPBF

Power Supply Controllers, Monitors Overview

The LTC1921CMS8#TRPBF is a dual-channel supply and fuse monitor manufactured by Analog Devices Inc. It operates within an input voltage range of 10V to 80V and is housed in an 8-pin MSOP package. The device features two independent channels for monitoring positive supply voltages or current through shunt resistors. It includes an internal reference and adjustable hysteresis for fault detection. The component supports programmable delay times to filter noise and ensure stable operation under transient conditions.

Power Supply Controllers, Monitors Feature Summary

• Dual-channel architecture for simultaneous monitoring of two independent power supplies or fuses
• Integrated internal reference eliminates the need for external precision voltage references
• Adjustable hysteresis capability allows customization of trip point margins to prevent false triggering

Power Supply Controllers, Monitors Applications

• Monitoring high-voltage industrial power buses
• Fuse status detection in automotive electronics
• Supply voltage supervision in telecommunications equipment

Power Supply Controllers, Monitors Procurement Notes

Verify the specific suffix TRPBF indicates tape-and-reel packaging when sourcing. Confirm the CMS8 designation corresponds to the commercial temperature range of 0°C to 70°C. Ensure compatibility with the required operating voltage range of 10V to 80V for your specific application design constraints.

Power Supply Controllers, Monitors Selection Notes

Select this component when dual-channel supervision is required for voltages exceeding standard logic levels. The integrated reference simplifies board layout compared to discrete comparator solutions. Consider the MSOP-8 footprint for space-constrained designs requiring high-voltage tolerance without external level shifting.

Power Supply Controllers, Monitors Part Context

This part belongs to the LTC1921 family of supply monitors. It serves as a specialized interface between high-voltage power domains and low-voltage control logic, providing reliable fault indication for system protection schemes.

Power Supply Controllers, Monitors Replacement Considerations

Check for pin-compatible alternatives such as the LTC1921CS8 if tube packaging is preferred over reel. Verify that any substitute maintains the 10V to 80V input range and dual-channel functionality.
