CAT8801YTB-GT3

Supervisors Overview

The CAT8801YTB-GT3 is a voltage supervisory circuit manufactured by onsemi, designed for low-current applications. It operates within a supply voltage range of 1.2 V to 5.5 V and features a push-pull output type. The device monitors a single input with a threshold voltage of 2.19 V. It provides a reset delay time of 270 ms and consumes only 200 nA of operating current. The component is housed in an SOT-23-3 package and functions reliably across an industrial temperature range from -40°C to +85°C.

Supervisors Feature Summary

• Ultra-low power consumption suitable for battery-operated systems
• Push-pull output configuration for direct interface compatibility
• Precision voltage monitoring with fixed threshold options

Supervisors Applications

• Microprocessor power supply supervision
• Battery-powered portable devices
• Industrial control system reset circuits

Supervisors Procurement Notes

Verify the specific suffix YTB corresponds to the required threshold voltage and package variant before ordering. Confirm end-of-life status and availability through authorized distributors, as this component may be discontinued or subject to limited stock constraints. Ensure compliance with RoHS directives if applicable to your manufacturing requirements.

Supervisors Selection Notes

Select this component when ultra-low quiescent current is critical for extending battery life in portable electronics. The push-pull output allows for flexible logic level interfacing without additional pull-up resistors. Consider the fixed threshold voltage of 2.19 V to ensure it aligns with the monitored rail's minimum operating requirement for reliable reset generation.

Supervisors Part Context

This part belongs to the CAT8801 series of microprocessor supervisors from onsemi. These devices are engineered to replace older supervisor ICs in applications where operating current is a primary design constraint. The series offers various threshold voltages and packages to support diverse digital system reset needs.

Supervisors Replacement Considerations

Check for CAT8801 variants with different suffixes (e.g., ZSD) if alternative packaging like SC-70-3 is preferred. Verify functional equivalence with other onsemi supervisors such as the CAT809 or CAT810 series, noting differences in output polarity and threshold precision.
