CAT8801ZSD-GT3

Supervisors Overview

The CAT8801ZSD-GT3 is a voltage supervisory circuit manufactured by onsemi, designed for low-current applications. It operates within a supply voltage range of 1.2V to 5.5V and features a push-pull output type. The device monitors a single input channel with a fixed threshold voltage of 2.32V. It provides a reset delay time of 270ms and consumes only 200nA of operating current. The component is housed in an SC-70-3 surface-mount package and supports a power dissipation of 320mW. It functions without manual reset or watchdog timer capabilities.

Supervisors Feature Summary

• Monitors system voltage levels with a fixed threshold to ensure stable operation
• Provides active-low reset signal via push-pull output interface
• Optimized for ultra-low power consumption in portable devices

Supervisors Applications

• Portable consumer electronics requiring voltage supervision
• Battery-powered systems needing low quiescent current monitoring
• Embedded circuits requiring simple power-on reset functionality

Supervisors Procurement Notes

Verify the specific suffix GT3 indicates tape and reel packaging configuration when sourcing. Confirm the SC-70-3 package variant matches your PCB footprint requirements. Check current lifecycle status as distribution availability may vary across regions. Ensure compatibility with your system's voltage range before integration.

Supervisors Selection Notes

Select this component when a fixed 2.32V threshold is required for voltage monitoring. Choose the SC-70-3 package for compact surface-mount designs. Consider the 200nA current draw for battery-sensitive applications. Verify that the 270ms reset delay meets your system timing constraints.

Supervisors Part Context

This part belongs to the CAT8801 series of voltage supervisors from onsemi. It shares functional similarities with other parts in the family but differs in package type and specific electrical parameters. The ZSD suffix denotes the SC-70-3 package and specific threshold characteristics.

Supervisors Replacement Considerations

Direct substitutes include CAT8801YTB-GT3, which offers similar functionality in an SOT-23-3 package. Verify pinout compatibility and threshold voltage alignment when considering alternative packages within the same series.
