TL7702BCPG4

Product Overview

Category: Integrated Circuit (IC)

Use: Voltage Supervisor

Characteristics: - Monitors the voltage level of a power supply - Generates a reset signal when the voltage falls below a specified threshold - Prevents erratic behavior or data corruption in electronic systems during power fluctuations

Package: Ceramic Dual-In-Line Package (CDIP)

Essence: The TL7702BCPG4 is a voltage supervisor IC designed to ensure stable operation of electronic systems by monitoring the power supply voltage and generating a reset signal when it falls below a predetermined threshold.

Packaging/Quantity: The TL7702BCPG4 is typically sold in reels or tubes, with each reel/tube containing a specific quantity of ICs. The exact packaging and quantity may vary depending on the supplier.

• Output Type: Active-Low Push-Pull

Detailed Pin Configuration

The TL7702BCPG4 has a total of eight pins:

1. VCC: Power supply input pin
2. GND: Ground reference pin
3. MR: Manual reset input pin
4. RESET: Reset output pin
5. TH: Threshold selection pin
6. CT: Capacitor connection pin for reset timeout period adjustment
7. OUT: Open-drain output pin for power-good indication
8. NC: No connection pin (unused)

Functional Features

• Monitors the power supply voltage continuously
• Generates a reset signal when the voltage falls below the selected threshold
• Provides manual reset capability through the MR pin
• Allows adjustment of the reset timeout period using an external capacitor connected to the CT pin
• Includes an open-drain output pin (OUT) for power-good indication

Advantages and Disadvantages

Advantages: - Ensures reliable operation of electronic systems during power fluctuations - Offers flexibility in selecting the reset threshold voltage - Provides manual reset capability for system debugging or maintenance - Adjustable reset timeout period allows customization for specific applications - Power-good indication through the OUT pin enhances system monitoring capabilities

Disadvantages: - Requires additional external components (capacitor) for timeout period adjustment - Limited number of available reset threshold voltage options

Working Principles

The TL7702BCPG4 operates by comparing the power supply voltage with the selected threshold voltage. When the voltage drops below the threshold, the IC generates a reset signal, which can be used to initialize or restart the system. The reset signal remains active until the voltage rises above the threshold and the reset timeout period elapses.

Detailed Application Field Plans

The TL7702BCPG4 is widely used in various electronic systems where stable operation is critical. Some common application fields include:

1. Microcontrollers and microprocessors
2. Industrial control systems
3. Automotive electronics
4. Power management circuits
5. Communication equipment
