LTC1232CS8#TRPBF

Supervisors Overview

The LTC1232CS8#TRPBF is a microprocessor supervisory circuit manufactured by Analog Devices Inc. It operates within a supply voltage range of 2.5 V to 5.5 V and consumes 500 uA of operating current. The device features two independent voltage threshold monitors set at 4.37 V and 4.62 V, providing active high, active low, and open drain outputs. It includes a watchdog timer with a reset delay time of 610 ms and maintains an accuracy of 2.5%. Designed for surface mount applications, it is housed in an SOIC-8 package.

Supervisors Feature Summary

• Dual independent voltage monitoring channels with configurable output polarities
• Integrated watchdog timer functionality for system reliability
• High precision voltage threshold detection with specified accuracy

Supervisors Applications

• Microprocessor power supply supervision
• Battery backup switching circuits
• Industrial control system monitoring

Supervisors Procurement Notes

Verify the specific suffix against official Analog Devices documentation to confirm pinout and electrical characteristics match design requirements. Confirm RoHS compliance status through the manufacturer's datasheet. Ensure the SOIC-8 package dimensions align with PCB layout constraints. Validate thermal performance specifications for the intended operating environment before finalizing procurement decisions.

Supervisors Selection Notes

Select this component when dual voltage thresholds are required for complex power sequencing or fault detection. Compare the 500 uA quiescent current against lower-power alternatives if battery life is critical. Evaluate the 610 ms reset delay against system startup timing requirements. Consider the 2.5% accuracy tolerance relative to the sensitivity of the monitored voltage rails.

Supervisors Part Context

This part belongs to the LTC1232 series of supervisory circuits designed for protecting sensitive electronic systems from power anomalies. It serves as a dedicated solution for monitoring multiple voltage levels simultaneously without requiring external components for basic threshold comparison functions.

Supervisors Replacement Considerations

The LT1232CS8#PBF is a confirmed substitute part number within the same product family.
