CAT1232LPZ-G

Supervisors Overview

The CAT1232LPZ-G is a microprocessor supervisor IC manufactured by onsemi, designed to monitor system power supply voltages and manage reset signals. It supports selectable reset voltage tolerances of 4.37V and 4.62V, making it suitable for both 5V and 3.3V systems. The device features an open-drain or push-pull output configuration with active-high or active-low reset options. It includes a manual reset input and offers adjustable or selectable reset timeouts. Operating within a temperature range of -40°C to +85°C, it is housed in an 8-MSOP package.

Supervisors Feature Summary

• Monitors single-channel power supply voltage to detect out-of-tolerance conditions
• Provides hardware reset generation for microprocessors during power failures or stalls
• Supports manual reset switch debouncing via dedicated input pin
• Offers configurable reset polarity and output drive types

Supervisors Applications

• Microprocessor reset circuitry in embedded systems
• Power supply monitoring for 5V and 3.3V logic circuits
• System recovery mechanisms after brown-out events
• Manual reset switch interface in industrial control panels

Supervisors Procurement Notes

Verify the exact suffix 'GT3' against official onsemi documentation, as distributor listings may vary. Confirm package type matches 8-MSOP specifications. Check current product status as some variants are marked discontinued. Ensure compatibility with required reset threshold voltage (4.37V or 4.62V) for your specific application design.

Supervisors Selection Notes

Select this component when a single-channel supervisor with selectable voltage tolerance is required. Compare with CAT1232LPV for SOIC package alternatives. Consider reset timeout requirements and output drive capability before finalizing. Verify operating temperature range meets environmental constraints. Ensure manual reset functionality is needed for the target design.

Supervisors Part Context

Part of the CAT1232/CAT1832 family of microprocessor supervisors. Designed as a drop-in replacement for legacy Maxim/Dallas Semiconductor DS1232LP/DS1832 devices. Manufactured by onsemi following Catalyst Semiconductor acquisition. Focuses on reliable system reset management for digital logic applications.

Supervisors Replacement Considerations

CAT1232LPV-GT3 serves as a direct package alternative in 8-SOIC format. Legacy equivalents include Maxim DS1232LP and Dallas DS1832. Verify pinout compatibility and electrical parameters before substitution. Check if updated onsemi variants offer improved specifications.
