LTC2903CS6-A1#TRPBF

Supervisors Overview

The LTC2903CS6-A1#TRPBF is a supervisory circuit manufactured by Analog Devices Inc., designed for precise monitoring of four independent voltage rails. It operates within a supply voltage range of 1.7V to 5.5V and features an open-drain reset output. The device is housed in a compact 6-lead TSOT-23 package, suitable for surface-mount applications. It draws a typical quiescent current of 20µA, ensuring efficient power management in battery-operated systems.

Supervisors Feature Summary

• Monitors four independent voltage inputs with precision thresholds
• Provides a single open-drain reset output signal
• Operates at low supply voltages down to 1.7V
• Compact 6-lead TSOT-23 surface-mount packaging

Supervisors Applications

• Portable electronic devices requiring multi-rail supervision
• Battery-powered systems with low power constraints
• Embedded controllers needing voltage integrity checks
• Industrial equipment monitoring critical power lines

Supervisors Procurement Notes

Verify component authenticity through authorized Analog Devices distributors or certified partners. Confirm the specific suffix A1 matches design requirements for threshold settings. Check current availability status as supply may be limited. Ensure proper handling procedures for ESD-sensitive surface-mount components during assembly.

Supervisors Selection Notes

Select this part when four-channel voltage monitoring is required in space-constrained designs. Consider the 1.7V minimum operating voltage for compatibility with low-voltage logic families. Evaluate the 20µA quiescent current against system power budgets. Verify that the open-drain output interface aligns with downstream controller input requirements.

Supervisors Part Context

This component belongs to the LTC2903 series of supervisory circuits from Analog Devices. It shares functional similarities with other parts in the family but differs in package type and specific threshold configurations. The CS6 designation indicates the TSOT-23-6 package variant, while the A1 suffix defines the specific monitor thresholds.

Supervisors Replacement Considerations

Direct substitutes include other LTC2903 variants with compatible packages and thresholds. Cross-reference with LTC2903CS6-D1#TRPBF for similar functionality but different threshold settings. Ensure any replacement maintains the 4-channel monitoring capability and open-drain output structure.
