CAT1162W-45TE13

Supervisors Overview

The CAT1162WI-45-T3 is a voltage supervisory circuit manufactured by onsemi, designed for CPU support applications. It integrates a 16K-bit I2C serial EEPROM with hardware write protection and a precision reset controller. The device monitors a single input channel with a threshold voltage of 4.5 V and an overvoltage threshold of 4.75 V. It features active high, active low, and open drain outputs with a manual reset capability and a reset delay time of 270 ms. Operating within a supply voltage range of 2.7 V to 6 V, it consumes 3 mA of working current. The component is housed in an SOIC-Wide-8 package and operates between -40°C and +85°C.

Supervisors Feature Summary

• Integrates 16K-bit I2C serial EEPROM with hardware memory write protection
• Provides system power supervision with brown-out protection
• Supports manual reset functionality with configurable output types
• Eliminates need for external components through integrated supervisory solution

Supervisors Applications

• Microcontroller-based systems requiring memory and supervision
• CPU support circuits with integrated storage
• Power supply monitoring in embedded devices

Supervisors Procurement Notes

Verify the exact part number suffix against official documentation, as variations such as T3 or G may indicate different packaging or compliance statuses. Confirm availability status, as this component is listed as obsolete in multiple distributor records. Ensure compatibility with existing PCB layouts for the SOIC-Wide-8 package. Cross-reference electrical parameters like threshold voltages and operating temperatures with the specific datasheet revision to avoid integration errors during procurement.

Supervisors Selection Notes

Select this component when a combined memory and supervision solution is required for microcontroller systems. The integrated 16K EEPROM reduces board space compared to discrete solutions. Consider the absence of a watchdog timer in the CAT1162 variant versus the CAT1161 if software glitch recovery is not needed. Verify that the 4.5 V threshold aligns with the target system's voltage levels. The SOIC-Wide-8 package offers a suitable footprint for surface-mount assembly.

Supervisors Part Context

The CAT1162 series belongs to onsemi's line of supervisory circuits with I2C serial CMOS EEPROM. It serves as a lower-cost alternative to the CAT1161 by omitting the watchdog timer feature while retaining the 16K memory and reset controller. This family provides a complete memory and supervisory solution for microcontroller-based systems, integrating hardware write protection and brown-out detection in low-power CMOS technology.
