CAT823RSDI-GT3 Description

Short technical summary and product information.

The CAT823RSDI-GT3 from ON Semiconductor is a system supervisory voltage reset IC with integrated watchdog and manual reset functions. It monitors system voltage and maintains a reset output until the voltage reaches a specified trip value and stabilizes. The device includes a watchdog timer input to monitor system signals and can initiate a reset if a signal fails to change state within a timeout period. Additionally, a manual reset input allows for reset initiation via a pushbutton or processor signal.

 

This supervisor IC operates within a temperature range of -40°C to 85°C and is available in a compact SC-70-5 package, suitable for surface mount applications. It is designed for use with 3.0, 3.3, and 5.0 V systems, featuring an accurate under-voltage monitoring capability and brownout detection. The CAT823RSDI-GT3 is pin and function compatible with MAX823/24 products and is Pb-free, halogen-free, BFR-free, and RoHS compliant.

 

Key electrical characteristics include an operating voltage of 2.63V, an active low reset output with a push-pull totem pole configuration, and a minimum reset timeout of 140ms. It monitors a single voltage and is ideal for microprocessor and microcontroller-based systems, intelligent instruments, control systems, and portable equipment.
