max1232csa Description

Short technical summary and product information.

The MAX1232CSA is a microprocessor supervisory circuit from Maxim Integrated, providing critical μP housekeeping and power-supply supervision functions. It consumes significantly less power than the DS1232, making it an efficient choice for reliable μP systems.

Key features include a precision voltage monitor with adjustable +4.5V or +4.75V thresholds and a power-OK/reset pulse width of at least 250ms. It also incorporates a digitally programmable watchdog timer with selectable timeout settings of 150ms, 600ms, or 1.2s, ensuring software execution monitoring. A debounced manual reset input allows for external override.

This supervisory circuit is designed for applications such as computers, controllers, intelligent instruments, and critical μP power monitoring. It requires no external components, simplifying design and implementation. The MAX1232CSA is available in an 8-pin SOIC package, suitable for surface mount applications.

It operates within a temperature range of 0°C to +70°C and supports voltage tolerance selection of 5% or 10%. The MAX1232CSA serves as a plug-in upgrade for the Dallas DS1232, offering enhanced performance and lower power consumption.
