The CAT812RTBI-GT3 is a microprocessor supervisory circuit designed to monitor power supply voltages, specifically featuring an active HIGH reset output. It is capable of monitoring various voltage levels, including +5.0 V, +3.3 V, +3.0 V, and +2.5 V, with precision tolerances of ±5%, ±10%, and ±20%. The device includes a manual reset input and is a direct replacement for the MAX812 in applications that operate within an industrial temperature range of -40°C to +85°C. The CAT812 asserts the reset signal when the power supply voltage falls below a preset threshold and maintains the reset state for at least 140 ms after the voltage rises above the threshold. It operates with a low supply current of 6 µA and is designed to ignore fast transients on the power supply, ensuring reliable operation even at Vcc levels as low as 1.0 V. The device is packaged in a compact 4-pin SOT-143 configuration, making it suitable for various applications, including computers, servers, embedded control systems, and wireless communications.
