Package

The TPS3707-33DGNRG4 comes in a small 8-pin MSOP package.

Essence

This voltage supervisor ensures that the voltage level in an electronic system remains within the desired range, preventing potential damage or malfunction.

Packaging/Quantity

The TPS3707-33DGNRG4 is typically packaged in reels, with 2500 units per reel.

Specifications

• Supply voltage range: 1.8V to 6.5V
• Threshold accuracy: ±1.5%
• Operating current: 5µA (typical)
• Output type: Open-drain
• Reset timeout period: 200ms (typical)
• Temperature range: -40°C to 125°C

Detailed Pin Configuration

The TPS3707-33DGNRG4 has the following pin configuration:

1. GND (Ground)
2. VDD (Supply voltage)
3. MR (Manual reset input)
4. RESET (Reset output)
5. TH (Threshold adjust)
6. HYST (Hysteresis adjust)
7. NC (No connection)
8. NC (No connection)

Functional Features

• Monitors supply voltage and generates a reset signal when it falls below the threshold.
• Adjustable threshold and hysteresis settings for flexibility in different applications.
• Open-drain output allows easy interfacing with other devices.
• Low quiescent current ensures minimal power consumption.

Advantages

• Reliable voltage monitoring prevents system damage or malfunction.
• Wide operating temperature range enables usage in various environments.
• Adjustable threshold and hysteresis settings offer customization options.
• Low quiescent current minimizes power consumption.

Disadvantages

• Limited to a specific voltage threshold (3.3V in this case).
• Requires additional external components for proper functionality.

Working Principles

The TPS3707-33DGNRG4 operates by continuously monitoring the supply voltage. When the voltage falls below the set threshold, it triggers the reset output, indicating a power failure or an abnormal condition. The adjustable hysteresis feature helps prevent false triggering due to voltage fluctuations near the threshold level.

Detailed Application Field Plans

The TPS3707-33DGNRG4 finds application in various electronic systems where voltage monitoring is critical. Some potential fields of application include:

1. Power supply units
2. Battery-powered devices
3. Industrial control systems
4. Automotive electronics
5. Medical equipment
