CAT1162W45

Supervisors Overview

The CAT1162W45 is a voltage supervisory circuit manufactured by onsemi, designed for CPU supervision applications. It integrates a 16K I2C EEPROM with the supervisor functionality in an 8-SOIC package. The device monitors a single input channel with a threshold voltage of 4.5 V and features a reset delay time of 270 ms. It operates within a supply voltage range of 2.7 V to 6 V and supports manual reset inputs. The output types include active high, active low, and open drain configurations. The component functions within a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Integrates 16K I2C EEPROM with voltage supervision
• Supports multiple output polarities including active high, active low, and open drain
• Includes manual reset capability for system control

Supervisors Applications

• CPU power supply monitoring
• Embedded systems requiring integrated memory and supervision
• Industrial control units

Supervisors Procurement Notes

Verify the exact suffix (e.g., WI-45-T3) as datasheets may list generic part numbers like CAT1162W45 while distributors specify full ordering codes. Confirm availability status as this series may be discontinued or subject to lifecycle changes. Ensure the selected variant matches the required package type and operating temperature range for your specific design constraints before finalizing procurement.

Supervisors Selection Notes

Select this component when a combined voltage supervisor and non-volatile memory solution is required for space-constrained designs. The 8-SOIC package offers a compact footprint suitable for surface mount assembly. Consider the 4.5 V threshold if the target system operates at standard logic levels. Verify that the integrated EEPROM meets the endurance and retention requirements of the application.

Supervisors Part Context

The CAT1162 series from onsemi combines power management supervision with data storage capabilities. This specific model targets applications needing reliable reset generation alongside persistent data storage without requiring separate components. It belongs to the PMIC - Power Management ICs subcategory under Supervisory Circuits.

Supervisors Replacement Considerations

Check for direct substitutes within the CAT1162 family with different voltage thresholds or packages. Verify compatibility with existing PCB footprints if switching between SOIC and other variants.
