TPS3850H25QDRCRQ1

The TPS3850H25QDRCRQ1 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 device is particularly useful in applications where reliable operation is critical, such as in automotive, industrial, and consumer electronics.

Key Features:

1. Voltage Monitoring: The TPS3850H25QDRCRQ1 monitors a supply voltage and generates a reset signal when the voltage drops below a predetermined threshold. This ensures that the connected microcontroller or digital device does not operate under unsafe voltage conditions.

2. Adjustable Reset Threshold: The device allows for an adjustable reset threshold, which can be set to various levels depending on the specific requirements of the application. This flexibility makes it suitable for a wide range of voltage levels.

3. Active-Low Reset Output: The reset output is active-low, meaning that it goes low when a reset condition is triggered. This output can be connected directly to the reset pin of a microcontroller.

4. Fast Reset Response Time: The TPS3850H25QDRCRQ1 features a fast response time, ensuring that the reset signal is generated quickly when the supply voltage drops, minimizing the risk of improper operation of the connected devices.

5. Low Quiescent Current: The device is designed to operate with low quiescent current, making it suitable for battery-powered applications where power efficiency is crucial.

6. Wide Operating Voltage Range: The TPS3850H25QDRCRQ1 can operate over a wide voltage range, making it versatile for different power supply configurations.

7. Temperature Range: The IC is rated for operation over an extended temperature range, which is essential for applications in harsh environments.

8. Package Type: The device is available in a compact QFN (Quad Flat No-lead) package, which is suitable for space-constrained designs.

Applications:

• Microcontroller Reset: Ensures that microcontrollers start up in a known state by providing a reset signal during power-up and power-down conditions.
• Automotive Systems: Used in automotive electronics to monitor supply voltages and ensure reliable operation of critical systems.
• Industrial Equipment: Provides voltage supervision in industrial control systems, ensuring that equipment operates safely and reliably.
• Consumer Electronics: Used in various consumer devices to protect against voltage fluctuations and ensure proper operation.

Conclusion:

The TPS3850H25QDRCRQ1 from Texas Instruments is a robust and versatile voltage supervisor IC that provides essential monitoring and reset functionality for a wide range of electronic applications.
