DS1232S Description

Short technical summary and product information.

The DS1232S MicroMonitor Chip by Dallas Semiconductor is an integrated circuit designed to safeguard microprocessor-based systems. It monitors three vital conditions: power supply status, software execution, and external override.

Key features include accurate 5% or 10% microprocessor power supply monitoring, a watchdog timer to detect software failures, and a pushbutton reset input for external override control. The device halts and restarts an out-of-control microprocessor, holds it in check during power transients, and automatically restarts it after power failure.

Available in a space-saving 8-pin mini-DIP or an optional 16-pin SOIC surface mount package, the DS1232S operates within an industrial temperature range of -40°C to +85°C. Its precise voltage monitoring and reset capabilities eliminate the need for discrete components, simplifying system design and improving reliability.
