TC1232EOA Description

Short technical summary and product information.

The TC1232EOA from Microchip Technology is a fully-integrated processor supervisor designed to safeguard system stability. It offers precision voltage monitoring with adjustable trip points of +4.5V or +4.75V, ensuring reliable power-on reset control.

 

The device includes an adjustable watchdog timer with selectable timeouts of 150 ms, 600 ms, or 1.2 seconds, which monitors microprocessor activity and issues a reset if the processor fails to provide a periodic signal. A debounced manual reset input allows for external override control.

 

Operating within a voltage range of 4.0V to 5.5V, the TC1232EOA provides a minimum reset pulse width of 250 ms to ensure stable system start-up. It requires no external components and is available in a space-saving 8-pin SOIC package, suitable for surface mount applications.

 

This supervisor IC is ideal for applications requiring robust processor monitoring and reset management, contributing to overall system reliability and fault tolerance.
