CAT8801YSD-GT3

Supervisors Overview

The CAT8801YSD-GT3 is a voltage supervisory circuit manufactured by onsemi, designed for monitoring single-channel power supply voltages. It operates within a supply voltage range of 1.2 V to 5.5 V and features a push-pull output configuration. The device provides a reset delay time of 270 ms and functions with a low quiescent current of 200 nA. It is available in an SC-70-3 package and supports threshold voltages including 1.8 V, 2.5 V, 3 V, 3.3 V, and 5 V. The component is rated for operation between -40°C and +85°C.

Supervisors Feature Summary

• Monitors a single input voltage channel to ensure system stability
• Provides a push-pull active-low reset signal upon undervoltage detection
• Operates with ultra-low quiescent current for energy efficiency
• Supports multiple fixed threshold voltage options for flexibility

Supervisors Applications

• Portable battery-powered equipment requiring low standby current
• Microprocessor and microcontroller power supply supervision
• Smartphone and tablet internal voltage monitoring
• Wearable electronic devices with strict power constraints

Supervisors Procurement Notes

Verify the specific suffix code to confirm the exact threshold voltage and package type, as variations exist within the CAT8801 family. Confirm availability status, as this part may be discontinued or subject to limited distribution channels. Ensure compatibility with existing PCB footprint designs for the SC-70-3 package before finalizing procurement plans.

Supervisors Selection Notes

Select this component when a single-channel supervisor with a push-pull output is required for low-voltage applications. Consider the 270 ms reset delay and available threshold options against system timing requirements. Evaluate the SC-70-3 package size against board space limitations and verify that the operating temperature range meets environmental specifications.

Supervisors Part Context

This component belongs to the CAT8801 series of voltage supervisors from onsemi. The series offers various packages and threshold combinations to support diverse power management needs in compact electronic designs. It serves as a critical element for ensuring reliable system startup and recovery from brown-out conditions.

Supervisors Replacement Considerations

Check for direct pin-compatible alternatives within the CAT8801 series that match the required threshold voltage. Verify if newer generation supervisors offer improved performance metrics while maintaining the same package outline.
