CAT1232LPV-G

Supervisors Overview

The CAT1232LPV-G is a microprocessor supervisory circuit manufactured by onsemi, designed to monitor system power supply voltages. It provides reset signals for single-channel voltage supervision with selectable threshold options of 4.37V and 4.62V. The device supports both open-drain and push-pull output configurations, allowing for flexible interface compatibility with various logic families. It features adjustable or selectable reset timeouts to accommodate different system startup requirements. Operating across an industrial temperature range of -40°C to +85°C, it ensures reliable performance in demanding environments. The component is housed in an 8-SOIC surface-mount package.

Supervisors Feature Summary

• Monitors system power supply voltage to detect out-of-tolerance conditions
• Generates active-high or active-low reset signals upon power failure or manual input
• Supports selectable reset timeout durations for customized system recovery timing

Supervisors Applications

• Microprocessor reset circuits in embedded systems
• Power supply monitoring for digital logic boards
• Manual reset switch debouncing applications

Supervisors Procurement Notes

Verify the specific suffix and revision level against official datasheets to ensure correct threshold voltage selection and output configuration. Confirm that the 8-SOIC package dimensions match the target PCB footprint. Check current product status as distribution availability may vary due to lifecycle changes. Ensure environmental compliance requirements align with project specifications before finalizing procurement.

Supervisors Selection Notes

Select this component when a single-channel supervisor with selectable thresholds near 4.5V is required. Consider the output drive capability and polarity requirements relative to the connected processor. Evaluate the reset timeout needs against the system's power-up sequence timing constraints. Verify thermal operating limits suit the intended application environment.

Supervisors Part Context

This part belongs to the CAT1232/CAT1832 family of voltage supervisors originally developed by Catalyst Semiconductor and later acquired by onsemi. These devices serve as drop-in replacements for legacy Maxim/Dallas Semiconductor parts. The family focuses on providing reliable reset generation for microprocessors and memory systems under varying power conditions.

Supervisors Replacement Considerations

Public confirmed substitute part numbers include CAT1232LPZ-GT3 and CAT1232LPV-GT3.
