The CAT803MTBI-T3 is a supervisory circuit designed for use in microprocessor and microcontroller systems. It features a voltage monitor, watchdog timer, and manual reset input to ensure proper system operation. The voltage monitor continuously tracks the power supply voltage and resets the system if it falls below a certain threshold. The watchdog timer monitors the system's activity and resets it if it is not functioning properly. The manual reset input allows for a manual reset of the system if needed. The CAT803MTBI-T3 also has a low quiescent current and operates over a wide temperature range, making it suitable for a variety of applications. It comes in a compact SOT-23 package for easy integration into existing designs
