LTC1232CS8#PBF

Supervisors Overview

The LTC1232CS8#PBF is a supervisory circuit manufactured by Analog Devices Inc., designed for microprocessor reset applications. It operates within a supply voltage range up to 5.5 V and features a watchdog timer with a reset delay time of 610 ms. The device monitors input thresholds at 4.37 V and 4.62 V, offering an accuracy of 2.5%. It draws a typical operating power supply current of 500 uA and dissipates up to 500 mW. The component supports active high, active low, and open drain output types without manual reset functionality. It functions reliably across a temperature range from -40 C to +85 C.

Supervisors Feature Summary

• Integrates a watchdog timer for system monitoring
• Provides multiple output logic configurations including open drain

Supervisors Procurement Notes

Verify the specific suffix CS8 indicates the SOIC-8 package variant when sourcing. Confirm RoHS compliance status through official documentation prior to integration. Ensure the selected supplier provides valid traceability records for quality assurance purposes. Cross-reference the manufacturer part number against authorized distributor lists to avoid counterfeit components during procurement processes.

Supervisors Selection Notes

Select this component for designs requiring integrated watchdog functionality alongside voltage supervision. Consider the 500 uA current draw for battery-sensitive applications. Verify that the 4.37 V and 4.62 V threshold options align with the target system voltage levels. Evaluate the -40 C to +85 C operating range against environmental requirements before finalizing the design choice.
