CAT1023WI30 Description

Short technical summary and product information.

The CAT1023WI30 from On Semiconductor is a supervisory circuit designed for microcontroller-based systems. It integrates a 2k-bit serial EEPROM with a system power supervisor, offering brown-out protection. This device operates over a voltage range of 2.7V to 5.5V and features a precision voltage monitor with a 3V threshold.

 

The supervisory functions include a watchdog timer and active high/low reset outputs, ensuring system stability during power fluctuations. The reset timeout is a minimum of 130ms. The CAT1023WI30 is available in an 8-SOIC package, suitable for surface mount applications.

 

This component is ideal for applications requiring reliable power monitoring and system reset capabilities. Its integrated EEPROM provides non-volatile data storage, while the watchdog timer helps maintain system integrity by resetting the system if software or hardware glitches occur.
