CAT8801XSD-GT3

Supervisors Overview

The CAT8801XSD-GT3 is a voltage supervisory circuit manufactured by onsemi, designed for monitoring single power supply rails. It operates within a supply voltage range of 1.2V to 5.5V and features a fixed threshold voltage of 2V. The device utilizes an SC-70-3 surface-mount package and provides an active-low push-pull output. Key electrical parameters include a minimum reset timeout of 140ms and a maximum operating temperature of +85°C. It is classified as a simple reset/power-on reset supervisor without manual reset or watchdog functionality.

Supervisors Feature Summary

• Provides hardware-based supervision for single voltage rails with active-low push-pull output
• Operates across a wide input voltage range from 1.2V to 5.5V
• Utilizes compact SC-70-3 surface-mount packaging for space-constrained designs

Supervisors Applications

• Portable electronic devices requiring low-voltage monitoring
• Battery-powered systems needing power-fail detection
• Embedded controllers requiring automatic reset upon power-up

Supervisors Procurement Notes

Verify component authenticity through authorized distributors due to obsolete status. Confirm package integrity and pin alignment against SC-70-3 specifications. Review datasheet for thermal dissipation limits under specific load conditions. Ensure compatibility with system voltage levels before integration into final assembly.

Supervisors Selection Notes

Select this component when a fixed 2V threshold is required for single-supervision applications. Consider the SC-70-3 footprint constraints during PCB layout. Evaluate the 140ms minimum reset delay against system startup timing requirements. Verify that the active-low output logic aligns with the target microcontroller or processor input specifications.
