LTC2908CTS8-A1#TRMPBF

Supervisors Overview

The LTC2908CTS8-A1#TRMPBF is a six-input power supply monitor manufactured by Analog Devices Inc. It operates within a supply voltage range of 2.7V to 5.5V and features a low quiescent current of 50µA. The device provides active-low reset outputs for five fixed thresholds (4.675V, 3.086V, 2.338V, 1.683V, and an adjustable threshold) and one open-drain output. It is housed in an 8-pin TSOT-23 package with a maximum operating temperature of +70°C.

Supervisors Feature Summary

• Six independent input channels for comprehensive multi-rail system monitoring
• Integrated precision internal reference ensures accurate threshold detection without external components
• Configurable watchdog timer with selectable timeout periods for processor supervision
• Active-low reset output with push-pull or open-drain configuration options

Supervisors Applications

• Portable electronic devices requiring compact multi-voltage supervision
• Embedded systems with multiple logic and analog power rails
• Industrial control units needing reliable processor reset management
• Battery-powered equipment prioritizing low standby current consumption

Supervisors Procurement Notes

Verify the specific suffix A1 against the target design requirements to ensure correct fixed threshold voltages match the monitored rails. Confirm the TRMPBF designation indicates tape-and-reel packaging suitable for automated surface-mount assembly processes. Cross-reference the manufacturer's latest documentation for any updates regarding compliance standards or recommended operating conditions prior to final procurement.

Supervisors Selection Notes

Select this component when the application demands simultaneous monitoring of six distinct voltage levels within a minimal footprint. Evaluate the fixed threshold values against the system's critical rail specifications to confirm adequate margin. Consider the low quiescent current characteristic for battery-operated designs where standby power efficiency is a primary constraint compared to higher-current alternatives.

Supervisors Part Context

This part belongs to the LTC2908 series of high-precision power supply monitors designed for complex embedded architectures. It complements other supervisory circuits by offering increased channel density in a small outline package. The series supports various threshold configurations to accommodate diverse industry-standard voltage levels commonly found in modern digital and mixed-signal systems.

Supervisors Replacement Considerations

LTC2908IDDB-A1#PBF offers identical electrical performance in a different package format.
