Detailed Pin Configuration

The TPS3836K33DBVR has three pins:

1. GND: Ground connection.
2. VDD: Power supply input.
3. RESET: Active-low reset output.

Functional Features

• Undervoltage Detection: Monitors the input voltage and asserts the reset signal when it falls below the programmed threshold.
• Adjustable Threshold: The threshold voltage can be adjusted using external resistors, allowing flexibility in voltage monitoring.
• Hysteresis: Built-in hysteresis prevents false triggering by introducing a voltage difference between the rising and falling thresholds.
• Power-On Reset Delay: Provides a fixed delay before releasing the reset signal during power-up, ensuring stable system operation.

Advantages and Disadvantages

Advantages

• Low power consumption makes it suitable for battery-powered applications.
• Wide operating voltage range enables compatibility with various systems.
• Accurate threshold voltage ensures precise voltage monitoring.
• Small package size allows for space-efficient designs.
• Adjustable threshold voltage provides flexibility in voltage level detection.

Disadvantages

• Lack of integrated overvoltage protection.
• Limited number of pins restricts additional functionality without external circuitry.

Working Principles

The TPS3836K33DBVR operates by continuously monitoring the input voltage. When the voltage falls below the programmed threshold, the reset output is asserted, indicating a fault condition or low voltage. The reset signal remains active until the voltage rises above the threshold, providing a reliable indication of system status.

Detailed Application Field Plans

The TPS3836K33DBVR finds application in various fields, including:

1. Battery-Powered Devices: Ensures proper functioning by monitoring battery voltage levels and preventing undervoltage conditions.
2. Industrial Control Systems: Provides voltage supervision to safeguard critical components and prevent system failures.
3. Automotive Electronics: Monitors voltage levels in automotive systems, enabling early detection of potential faults.
4. Telecommunications Equipment: Ensures stable operation by monitoring power supply voltages and triggering appropriate actions during voltage fluctuations.
