LTC1232IS8#TRPBF

Supervisors Overview

The LTC1232IS8#TRPBF is a supervisory circuit manufactured by Analog Devices Inc., designed for microprocessor system monitoring. It operates within a supply voltage range of 2.65 V to 5.5 V and consumes a typical operating current of 500 uA. The device features dual threshold voltages of 4.37 V and 4.62 V with an accuracy of 2.5%. It provides active high, active low, and open drain output types, includes a watchdog timer, and has a reset delay time of 610 ms. The component is housed in an SOIC-8 package and supports surface mount installation.

Supervisors Feature Summary

• Dual threshold voltage detection capabilities for precise power monitoring
• Integrated watchdog timer functionality for system reliability
• Multiple output configuration options including active high, active low, and open drain

Supervisors Applications

• Microprocessor system supervision
• Power failure detection circuits
• Battery backup switching systems

Supervisors Procurement Notes

Verify the specific suffix against official Analog Devices documentation to confirm package type and temperature grade. Ensure compatibility with required threshold voltages and output configurations. Confirm RoHS compliance status through manufacturer datasheets. Validate that the SOIC-8 footprint matches design requirements. Check for any recent product change notices affecting specifications or availability.

Supervisors Selection Notes

Select this component when dual independent voltage thresholds are required for complex power sequencing. Consider the 500 uA quiescent current for battery-sensitive applications. Evaluate the need for manual reset capability, as this variant lacks it. Compare the 610 ms reset delay against system startup timing requirements. Verify that the SOIC-8 package fits the available PCB space constraints.
