The CAT811RTBI-GT3 is a microprocessor supervisory circuit designed to monitor power supplies, offering a manual reset input. It serves as a direct replacement for the MAX811 in applications that require operation over an industrial temperature range of -40¬8C to +85¬8C. The device generates a reset signal when the power supply voltage falls below a preset threshold and maintains this signal for at least 140 ms after the voltage rises above the threshold. The CAT811 supports various standard threshold levels for +5.0 V, +3.3 V, +3.0 V, and +2.5 V systems, with the ability to customize reset threshold values due to its underlying floating gate technology. It features a RESET output that is active LOW and is capable of maintaining correct output states at VCC levels as low as 1.0 V. The device has a low power supply current of 6 ¬µA and is available in a compact 4-pin SOT-143 package, compliant with RoHS standards. Applications for the CAT811 include computers, servers, laptops, wireless communications, embedded control systems, and various consumer electronics.
