The CAT811 is a compact 4-pin microprocessor power supply supervisor designed for industrial applications. It monitors the supply voltage, providing an active LOW reset signal when voltage drops below preset thresholds such as +5.0 V, +3.3 V, +3.0 V, or +2.5 V. Featuring a manual reset input and guaranteed reset active from 1.0 V Vcc, it offers high transient immunity, low supply current of 6–20 µA, and operation across -40°C to +85°C. Its small SOT-143 package makes it suitable for embedded control, communication systems, and power management modules.
