The CAT811STBI-GT3 is an IC (integrated circuit) component manufactured by ON Semiconductor. It is a voltage supervisor and microprocessor reset circuit designed to monitor the power supply voltage of a system and provide a reset signal to the microprocessor or other devices when the voltage falls below a specified threshold.
Key features of the CAT811STBI-GT3 include:
1. Precision Voltage Monitoring: It offers a precise monitoring of the power supply voltage with an adjustable threshold voltage. The threshold voltage can be set using external resistors.
2. Reset Signal Generation: The IC generates a reset signal when the power supply voltage drops below the threshold voltage. The reset signal is active-low and remains asserted for a fixed delay time after the voltage rises above the threshold voltage.
3. Adjustable Reset Delay: The reset delay time can be adjusted using an external capacitor. This feature allows designers to fine-tune the reset timing based on their specific system requirements.
4. Power-on Reset: The CAT811STBI-GT3 provides a power-on reset signal to ensure reliable system initialization. This signal is generated immediately after the power is applied to the circuit and remains asserted until the power supply voltage reaches the threshold voltage.
5. Low Power Consumption: The IC is designed to minimize power consumption, making it suitable for battery-powered applications.
6. Wide Operating Voltage Range: It operates over a wide voltage range, typically from 1.0V to 5
