TPS3422EGDRYR

The TPS3422EGDRYR is a voltage supervisor integrated circuit (IC) manufactured by Texas Instruments. It is designed to monitor power supply voltages and provide reset signals to microcontrollers and other digital devices, ensuring reliable operation during power-up, power-down, and brownout conditions.

Key Features:

1. Voltage Monitoring: The TPS3422 can monitor a variety of supply voltages, typically in the range of 1.5V to 5.5V. It is equipped with adjustable threshold settings, allowing it to be tailored to specific application requirements.

2. Reset Output: The IC provides a reset output signal that is asserted when the monitored voltage falls below a predetermined threshold. This output is typically active low and can be used to reset microcontrollers or other digital logic devices.

3. Debounce Time: The TPS3422 includes a built-in delay feature that prevents false triggering of the reset output due to transient voltage fluctuations. This debounce time can be configured to ensure stable operation.

4. Low Power Consumption: The device is designed for low power operation, making it suitable for battery-powered applications. It typically consumes only a few microamperes of current in its active state.

5. Temperature Range: The TPS3422 is rated for operation over an extended temperature range, typically from -40°C to +125°C, making it suitable for industrial and automotive applications.

6. Package Type: The TPS3422EGDRYR is housed in a small, surface-mount package (SOT-23), which is ideal for space-constrained designs. The compact form factor allows for easy integration into various circuit layouts.
