CAT1162LI-30-G

Supervisors Overview

The CAT1162LI-30-G is a voltage supervisory circuit manufactured by onsemi, designed for CPU systems with integrated 16K EEPROM. It features a threshold voltage of 3 V and supports active high, active low, and open drain output types. The device includes manual reset capability but lacks a watchdog timer or battery backup switch. It operates within a supply voltage range up to 6 V and has a reset delay time of 270 ms. The component is housed in an 8-pin PDIP package and functions across a temperature range from -40°C to +85°C.

Supervisors Feature Summary

• Integrates 16K serial CMOS EEPROM with hardware write protection
• Provides precision reset control with brown-out protection
• Supports multiple output configurations including active high, active low, and open drain
• Includes manual reset functionality

Supervisors Applications

• Microcontroller-based system power supervision
• CPU monitoring circuits requiring non-volatile memory
• Embedded systems needing hardware write protection

Supervisors Procurement Notes

Verify end-of-life status as the component is listed as discontinued. Confirm availability through authorized distributors or secondary markets. Check RoHS compliance details and ensure the PDIP-8 package matches design requirements. Validate that the absence of a watchdog timer meets system safety needs. Review datasheet for specific electrical characteristics before integration.

Supervisors Selection Notes

Select this part when a combined supervisory circuit and 16K EEPROM solution is required without a watchdog timer. Ensure the 3 V threshold aligns with the monitored rail. Consider the PDIP-8 package for through-hole mounting. Verify that the 270 ms reset delay is acceptable for the application timing constraints. Compare against CAT1161 if watchdog functionality is needed.

Supervisors Part Context

Part of the CAT1161/2 family integrating supervisory circuits with I2C serial CMOS EEPROM. The CAT1162 variant specifically excludes the watchdog timer found in the CAT1161 model. Designed for low-power CMOS applications in microcontroller systems. Manufactured by onsemi under the Catalyst brand lineage.

Supervisors Replacement Considerations

CAT1161LI-30-G offers similar features but includes a watchdog timer. CAT1162WI-30-G provides the same functionality in an SOIC-8 surface-mount package. Verify pin compatibility and electrical specifications when substituting.
