• Quiescent Current: 10µA (typical)

Detailed Pin Configuration

The TPS3825-33DBVR has three pins:

1. VDD: This pin is connected to the power supply voltage.
2. GND: This pin is connected to the ground.
3. RESET: This pin outputs a reset signal when the monitored voltage drops below the threshold.

Functional Features

• Undervoltage Detection: The TPS3825-33DBVR continuously monitors the input voltage and generates a reset signal if it falls below the specified threshold.
• Power-On Reset: It ensures that the system remains in a known state during power-up by generating a reset signal until the voltage reaches the desired level.
• Manual Reset Input: The device includes an additional pin that allows for manual reset control.

Advantages and Disadvantages

Advantages

• Low-power consumption makes it suitable for battery-powered applications.
• Wide operating voltage range enables compatibility with various systems.
• Small package size allows for easy integration into space-constrained designs.

Disadvantages

• The reset threshold voltage is fixed at 3.3V, limiting its use in systems requiring different voltage levels.
• Lack of adjustable features may restrict its applicability in certain scenarios.

Working Principles

The TPS3825-33DBVR operates by comparing the input voltage with the preset threshold. If the voltage drops below the threshold, the device generates a reset signal to ensure proper system operation. It continuously monitors the voltage and provides a stable output until the voltage rises above the threshold.

Detailed Application Field Plans

The TPS3825-33DBVR finds application in various electronic systems, including but not limited to: - Microcontrollers - Embedded systems - Power management units - Industrial automation - Automotive electronics
