TPS3851G30EDRBR

The TPS3851G30EDRBR is a voltage supervisor integrated circuit (IC) manufactured by Texas Instruments. It is designed to monitor power supply voltages and provide a reset signal to microcontrollers and other digital devices when the supply voltage falls below a specified threshold. This ensures that the system operates reliably and prevents erratic behavior during power fluctuations.

Key Features:

1. Voltage Monitoring: The TPS3851G30EDRBR monitors a supply voltage and provides a reset output when the voltage drops below a predetermined threshold. This specific model has a fixed threshold voltage of 3.0V.

2. Reset Output: The device features an active-low reset output (RESET) that is asserted when the monitored voltage is below the threshold. The reset signal remains active until the voltage returns to a safe level, ensuring that the system does not start operating until it is stable.

3. Wide Supply Voltage Range: The IC operates over a wide supply voltage range, typically from 1.0V to 5.5V, making it suitable for various applications.

4. Low Quiescent Current: The TPS3851G30EDRBR is designed for low power consumption, with a quiescent current typically around 1.5 µA, which is beneficial for battery-powered applications.

5. Fast Reset Response Time: The device features a fast reset response time, ensuring that the reset signal is generated quickly when the supply voltage drops, which is critical for maintaining system integrity.

6. Hysteresis: The IC includes built-in hysteresis to prevent false triggering of the reset output due to noise or small fluctuations in the supply voltage.

7. Temperature Range: The TPS3851G30EDRBR is rated for operation over an extended temperature range, typically from -40°C to +125°C, making it suitable for automotive and industrial applications.

8. Package Type: The device is available in a small, space-saving package (SOT-23), which is ideal for compact designs.

Applications:

The TPS3851G30EDRBR is commonly used in various applications, including:

• Microcontroller and microprocessor reset circuits
• Power management systems
• Automotive electronics
• Industrial control systems
• Battery-powered devices

Conclusion:

The TPS3851G30EDRBR from Texas Instruments is a reliable and efficient voltage supervisor that provides essential monitoring and reset functionality for digital systems. Its low power consumption, fast response time, and wide operating range make it an excellent choice for a variety of applications where voltage stability is critical.
