CAT872-50ULGT3

Supervisors Overview

The CAT872-50ULGT3 is a dual-input reset generator manufactured by onsemi, designed for processor supervision in microprocessor and microcontroller-based systems. It functions as a voltage supervisor that monitors two independent supply rails to ensure system stability. The device features an active-low open-drain output and operates within a supply voltage range of 2.7 V to 5.5 V. It is housed in a compact 6-pin ULLGA package suitable for surface-mount applications.

Supervisors Feature Summary

• Dual input reset generation for monitoring multiple power supplies
• Active low open drain output configuration
• Designed to restart systems when watchdog timers fail

Supervisors Applications

• Microprocessor system supervision
• Microcontroller based system reset generation
• Dual power supply monitoring circuits

Supervisors Procurement Notes

Verify the specific suffix GT3 corresponds to the tape and reel packaging format required for your assembly line. Confirm the ULLGA package dimensions match your PCB footprint design. Ensure the active-low output polarity aligns with your target controller's reset input requirements before finalizing procurement.

Supervisors Selection Notes

Select this component when dual-rail voltage monitoring is necessary for system reliability. It is appropriate for designs requiring automatic recovery from watchdog failures. Consider the 6-pin ULLGA package size if board space is constrained. Verify compatibility with the operating voltage range of the monitored supplies.

Supervisors Part Context

This part belongs to the CAT87x series of supervisory circuits from onsemi. These devices are engineered to provide reliable reset signals for digital logic systems. The series typically includes variants with different threshold voltages and pin configurations to suit various power management needs.

Supervisors Replacement Considerations

Check for other CAT87x family members with compatible threshold voltages. Verify pin-to-pin compatibility with existing designs. Ensure the replacement maintains the dual-input functionality if both rails require monitoring.
