LTC1232IS8#PBF

Supervisors Overview

The LTC1232IS8#PBF is a voltage supervisory circuit manufactured by Analog Devices Inc., housed in an SOIC-8 surface-mount package. It features dual threshold voltages of 4.37 V and 4.62 V for monitoring a single input. The device provides active high, active low, and open drain outputs with a reset delay time of 610 ms. Operating from a maximum supply voltage of 5.5 V, it draws a typical working current of 500 uA. The component includes a watchdog timer function but lacks manual reset and battery backup switching capabilities. It maintains an accuracy of 2.5% and operates within a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Integrates a watchdog timer for system reliability monitoring
• Provides multiple output configurations including active high, active low, and open drain
• Features dual independent voltage thresholds for precise power supervision

Supervisors Applications

• Microprocessor system power monitoring
• Embedded controller reset generation
• Industrial control board supervision

Supervisors Procurement Notes

Verify the specific suffix #PBF confirms lead-free compliance and RoHS status against the manufacturer's latest documentation. Confirm the SOIC-8 package dimensions match your PCB footprint requirements. Ensure the 4.37 V and 4.62 V thresholds align with your target supply voltage levels. Check for any obsolescence notices or lifecycle changes directly from Analog Devices before finalizing procurement plans.

Supervisors Selection Notes

Select this component when dual threshold monitoring is required without manual reset functionality. The integrated watchdog timer makes it suitable for systems needing automated fault recovery. Consider the 500 uA operating current for low-power applications. Verify that the 610 ms reset delay meets your system startup timing constraints. Ensure the SOIC-8 package is compatible with your assembly process.
