CAT872-15ULGT3

Supervisors Overview

The CAT872-15ULGT3 is a dual input reset generator from onsemi, designed to restart microprocessor and microcontroller-based systems when watchdog timers or other resetting mechanisms fail. It monitors two voltage inputs and provides an active low/open drain reset output. The device operates within a supply voltage range of 1.2V to 5.5V. It features a fixed reset delay time of 200ms typical. The component is housed in a 6-pin ULLGA package.

Supervisors Feature Summary

• Dual input reset generation for system reliability
• Active low open drain output configuration
• Designed to recover systems from failed reset mechanisms

Supervisors Applications

• Microprocessor system supervision
• Microcontroller based system restart
• Watchdog timer failure recovery

Supervisors Procurement Notes

Verify the specific suffix ULGT3 confirms the 6-pin ULLGA tape and reel packaging format. Confirm the -15 designation aligns with the required threshold voltage for your design. Check current lifecycle status as distribution channels may list varying availability levels. Ensure RoHS compliance documentation matches project requirements.

Supervisors Selection Notes

Select this part when dual voltage monitoring is required for critical system resets. The fixed 200ms delay suits applications where immediate reset is not mandatory. Verify that the 1.2V minimum operating voltage covers your lowest supply rail. The open drain output requires appropriate pull-up resistor selection for the target logic level.

Supervisors Part Context

This component belongs to the CAT872 family of dual input reset generators. It shares functional similarities with the CAT871 but offers specific pinout and threshold variations. The ULLGA package provides a compact footprint suitable for space-constrained portable and industrial electronics designs requiring robust power management.

Supervisors Replacement Considerations

Check for CAT872 variants with different threshold voltages if the 1.5V reference does not match system needs. Verify pin compatibility with alternative dual-input supervisors from other manufacturers before substitution.
