CAT150049TWI-GT3

Supervisors Overview

The CAT150049TWI-GT3 is a voltage supervisory circuit manufactured by onsemi, designed for power management applications. It operates within a supply voltage range of 2.5 V to 5.5 V and features a reset threshold voltage of 3.08 V with a minimum threshold of 3.04 V. The device provides a fixed reset timeout period of 140 ms and lacks a manual reset input or watchdog timer. It is housed in an SOIC-8 package and supports operation from -40°C to +85°C.

Supervisors Feature Summary

• Provides reliable voltage supervision with a fixed 140 ms reset timeout
• Operates across standard supply voltages including 2.5 V, 3.3 V, and 5 V
• Designed for surface-mount installation in compact electronic systems

Supervisors Applications

• Portable equipment requiring low-power monitoring
• Battery-powered devices needing voltage supervision
• Consumer electronics with strict power management requirements

Supervisors Procurement Notes

Verify component authenticity through authorized distributors. Confirm RoHS compliance status as indicated in official documentation. Check manufacturing status, as this part may be obsolete or subject to lifecycle changes. Ensure the SOIC-8 package variant matches your PCB footprint requirements before ordering.

Supervisors Selection Notes

Select this component when a single-channel supervisor with a fixed timeout is required. It is suitable for systems operating between 2.5 V and 5.5 V where manual reset functionality is unnecessary. Consider thermal performance and package constraints during integration into the final design.

Supervisors Part Context

This supervisory circuit belongs to onsemi's portfolio of power management integrated circuits. It serves as a critical component for ensuring system stability by monitoring supply voltage levels. The device integrates essential protection features without external components, simplifying board layout and reducing overall system cost.

Supervisors Replacement Considerations

Check for direct substitutes such as the CAT140021 series if I2C EEPROM integration is needed. Verify pin compatibility and electrical specifications against alternative supervisors from other manufacturers before substitution.
