LTC2908IDDB-B1#TRPBF

Supervisors Overview

The LTC2908IDDB-B1#TRPBF is a precision six-input supply monitor manufactured by Analog Devices Inc. It operates within an industrial temperature range of -40°C to +85°C and draws a typical quiescent current of 50 µA. The device features active-low or open-drain outputs for fault signaling. It is housed in an 8-lead DFN package with exposed pad, designed for surface-mount applications. This component provides a compact solution for monitoring multiple power rails simultaneously.

Supervisors Feature Summary

• Provides precise monitoring for up to six independent input supply voltages
• Features low quiescent current consumption suitable for battery-powered systems
• Offers flexible output configurations including active-low and open-drain options

Supervisors Applications

• Monitoring 12V, 3.3V, 2.5V, 1.8V, 1.5V, and 1.2V rails in embedded systems
• Processor supervisor circuits requiring multiple voltage thresholds
• Compact multi-supply monitoring solutions in industrial equipment

Supervisors Procurement Notes

Verify the specific suffix B1 against your design requirements, as it defines the fixed threshold voltages for the monitored inputs. Confirm availability status with authorized distributors, as supply constraints may apply. Ensure the 8-pin DFN package footprint matches your PCB layout. Cross-reference the datasheet for exact electrical characteristics relevant to your operating conditions.

Supervisors Selection Notes

Select this part when a system requires simultaneous supervision of six distinct voltage levels within a small form factor. The IDDB variant indicates industrial temperature rating. Consider the fixed threshold configuration associated with the B1 suffix during initial design phases, as these values are not adjustable. Evaluate the 50 µA standby current impact on overall system power budget.

Supervisors Part Context

The LTC2908 belongs to Analog Devices' family of precision supply monitors. It is designed for applications needing reliable voltage supervision without complex external components. The DFN package allows for space-constrained designs. Other variants in the series offer different threshold combinations or pin counts to suit various multi-rail architectures.

Supervisors Replacement Considerations

Check for other LTC2908 variants with different suffixes (e.g., A1, C1) if the fixed thresholds of the B1 version do not match your rail voltages. Verify pinout compatibility before substitution. No direct cross-brand replacements are confirmed in the provided data.
