The CAT811STBI-GT3 is a voltage supervisor designed for precise monitoring in industrial applications. It features:
Accuracy: Monitors voltages like +5V, +3.3V, etc., with ±5% precision.
Reset options: Offers both Active LOW (CAT811) and Active HIGH (CAT812) reset functions.
Low power consumption: Operates at a minimal 6 µA current from the power supply.
This voltage supervisor serves as an efficient, reliable monitoring solution in various industrial settings.
The CAT811STBI-GT3, a voltage supervisor by Rochester Electronics LLC, features:
Precise monitoring of various voltages (±5%, ±10%, etc.).
Two output configurations: Active LOW reset (CAT811) and Active HIGH reset (CAT812).
Manual reset input for user-controlled functionality.
Designed as a drop-in replacement for MAX811 and MAX812, suitable for industrial temperature range (-40°C to +85°C).
Low power consumption at 6 µA in the power supply current.

The package type of CAT811STBI-GT3 is SOT-143-4.
The CAT811STBI-GT3, a voltage supervisor by Rochester Electronics LLC, has a pin count of
Here's a brief overview of each pin function:
Input: Manual reset input. When this input is high (active), the device can be manually reset.
Output - Active LOW Reset: CAT811 output. This output goes low (active) when the monitored voltage condition is met, triggering a reset.
Power Supply: Connects to +5V power supply.
Ground: Common reference point for all signals.
Please note that the actual reset function depends on whether you use the CAT811 or the CAT812 configuration.
The manufacturer of the product CAT811STBI-GT3 is Rochester Electronics LLC. It is likely a specialized electronics company that focuses on designing and producing voltage supervisors and other high-tech components. Their products cater to various applications, ensuring efficient power management in industrial temperature ranges.
The CAT811STBI-GT3 voltage supervisor has various application areas, including efficient power management in electronic devices, reliable battery optimization in portable systems, and precise voltage regulation in industrial settings.
