MAX1232CSA Description

Short technical summary and product information.

The MAX1232CSA is a microprocessor (μP) supervisory circuit designed by Analog Devices to enhance system reliability. It monitors power supply and software execution, providing essential housekeeping functions. This circuit consumes significantly less power than the DS1232, making it an efficient choice for μP systems.

 

Key features include a reset pulse of at least 250ms duration on power-up, power-down, and brownout conditions. The voltage monitoring threshold is adjustable to +4.5V or +4.75V. A digitally programmable watchdog timer can be set for timeout periods of 150ms, 600ms, or 1.2s, ensuring software execution is monitored. It also includes a debounced manual reset input for external override.

 

The MAX1232CSA requires no external components and is available in an 8-pin SOIC package, suitable for surface mount applications. Its operating temperature range is 0°C to 70°C.

 

Applications for this supervisory circuit include computers, controllers, intelligent instruments, and critical μP power monitoring scenarios where reliable power and system supervision are paramount.
