DS1233 Description

Short technical summary and product information.

The DS1233 EconoReset from Dallas Semiconductor is a dedicated supervisor IC for microprocessor systems. It monitors critical power supply conditions, automatically restarting the microprocessor after a power failure. The device also features pushbutton reset control with internal debouncing circuitry.

 

Key electrical specifications include a 5V operating voltage with a threshold voltage of 4.375V. The DS1233 offers accurate power supply monitoring with selectable tolerances of 5%, 10%, or 15%. When an out-of-tolerance condition is detected or a pushbutton is released, it maintains the reset signal for approximately 350ms to allow system stabilization.

 

This supervisor IC is available in a low-cost TO-92 package or a surface-mount SOT-223 package. It operates within a temperature range of -40°C to +85°C, making it suitable for various environmental conditions. The DS1233 reduces the need for discrete components in power monitoring and reset circuits.
