Package

The TPS3619-33DGKR comes in a small form factor package, allowing for easy integration into various circuit designs.

Essence

The essence of the TPS3619-33DGKR lies in its ability to monitor and regulate voltage levels, ensuring stable operation of electronic systems.

Packaging/Quantity

The TPS3619-33DGKR is typically available in tape and reel packaging, with a quantity of 2500 units per reel.

Specifications

• Input voltage range: 2.5V to 6.5V
• Output voltage: 3.3V
• Operating temperature range: -40°C to +85°C
• Quiescent current: 10µA (typical)
• Power-on reset time: 20ms (typical)

Detailed Pin Configuration

The TPS3619-33DGKR has the following pin configuration:

1. GND (Ground)
2. VDD (Power supply input)
3. MR (Manual reset input)
4. RESET (Reset output)

Functional Features

1. Voltage Monitoring: The TPS3619-33DGKR continuously monitors the input voltage and compares it to a reference level.
2. Reset Generation: When the input voltage falls below the reference level, the device generates a reset signal to initiate system recovery.
3. Manual Reset: The MR pin allows for manual reset control, enabling the user to override the automatic reset function.

Advantages and Disadvantages

Advantages

• Reliable voltage supervision ensures stable operation of electronic systems.
• Low power consumption makes it suitable for battery-powered applications.
• Small form factor package enables easy integration into circuit designs.

Disadvantages

• Limited output voltage options (fixed at 3.3V).
• May not be suitable for applications requiring adjustable voltage thresholds.

Working Principles

The TPS3619-33DGKR operates by comparing the input voltage with a reference level. If the input voltage falls below the reference level, the device generates a reset signal. This reset signal can be used to initiate system recovery or perform other necessary actions. The device continuously monitors the voltage to ensure proper functioning of the electronic system.

Detailed Application Field Plans

The TPS3619-33DGKR finds application in various fields, including:

1. Power supply monitoring in embedded systems.
2. Battery-powered devices requiring voltage supervision.
3. Microcontroller-based systems where stable voltage levels are critical.
4. Industrial automation systems for reliable operation.
