TPS3307-33DGNRG4

Product Overview

Category

The TPS3307-33DGNRG4 belongs to the category of voltage supervisors.

Use

It is primarily used for monitoring and controlling the voltage levels in electronic systems.

Characteristics

• Voltage supervision: The TPS3307-33DGNRG4 ensures that the voltage remains within specified limits.
• Reset generation: It generates a reset signal when the voltage falls below or rises above the desired threshold.
• Low power consumption: The device operates with low power consumption, making it suitable for battery-powered applications.

Package

The TPS3307-33DGNRG4 comes in a small outline integrated circuit (SOIC) package.

Essence

The essence of the TPS3307-33DGNRG4 lies in its ability to provide reliable voltage monitoring and reset generation in electronic systems.

Packaging/Quantity

The TPS3307-33DGNRG4 is typically packaged in reels and is available in quantities of 2500 units per reel.

Specifications

• Supply voltage range: 2.5V to 6.5V
• Threshold voltage accuracy: ±1%
• Operating temperature range: -40°C to +85°C
• Quiescent current: 10µA (typical)
• Power-on reset delay time: 200ms (typical)

Detailed Pin Configuration

The TPS3307-33DGNRG4 has the following pin configuration:

1. GND (Ground)
2. VCC (Supply voltage)
3. MR (Manual reset)
4. RESET (Reset output)
5. VIT (Voltage input)

Functional Features

1. Voltage Monitoring: The TPS3307-33DGNRG4 continuously monitors the voltage level at the VIT pin.
2. Reset Generation: When the voltage falls below or rises above the threshold, the device generates a reset signal at the RESET pin.
3. Manual Reset: The MR pin allows for manual reset control, overriding the automatic reset generation.
4. Hysteresis: The device incorporates hysteresis to prevent false triggering of the reset signal due to voltage fluctuations.

Advantages and Disadvantages

Advantages

• Accurate voltage monitoring and reset generation.
• Low power consumption.
• Wide operating temperature range.
• Small form factor package.

Disadvantages

• Limited supply voltage range (2.5V to 6.5V).
• Manual reset functionality may not be required in all applications.

Working Principles

The TPS3307-33DGNRG4 operates by comparing the voltage at the VIT pin with a reference threshold. If the voltage falls below or rises above this threshold, the device triggers a reset signal. The hysteresis feature ensures that the reset signal is stable and immune to voltage fluctuations.

Detailed Application Field Plans

The TPS3307-33DGNRG4 finds application in various electronic systems where reliable voltage monitoring and reset generation are critical. Some potential application fields include:

1. Microcontrollers: Ensuring proper operation and protection against voltage fluctuations.
2. Power Supply Units: Monitoring input voltage levels and generating resets during fault conditions.
3. Industrial Control Systems: Maintaining stable voltage levels for precise control and preventing damage to sensitive components.
4. Automotive Electronics: Protecting electronic systems from voltage transients and ensuring safe operation.

Detailed and Complete Alternative Models

1. TPS3307-33DGNR: Similar to TPS3307-33DGNRG4 but without the reel packaging.
2. TPS3307-25DGNRG4: Variant with a different threshold voltage (2.5V) for specific applications.
3. TPS3307-18DGNRG4: Variant with a lower threshold voltage (1.8V) for low-power applications.

These alternative models offer similar functionality but cater to specific voltage requirements or packaging preferences.
