Detailed Pin Configuration

TLC7701IPWG4 has the following pin configuration:

1. GND (Ground)
2. RESET (Reset Output)
3. VDD (Supply Voltage)

Functional Features

Voltage Monitoring

TLC7701IPWG4 continuously monitors the supply voltage and compares it to the set threshold voltage. When the supply voltage drops below the threshold, the reset output is activated.

Adjustable Threshold Voltage

The threshold voltage can be adjusted by selecting the appropriate resistor values connected to the ADJ pin.

Open-Drain Output

The open-drain output allows for easy interfacing with other devices, such as microcontrollers or digital logic circuits.

Advantages and Disadvantages

Advantages

• Low supply current consumption
• Wide supply voltage range allows for versatile applications
• Adjustable threshold voltage provides flexibility
• Open-drain output simplifies circuit integration

Disadvantages

• Power-on reset delay time may not be suitable for all applications
• Limited reset threshold voltage options

Working Principles

TLC7701IPWG4 operates by comparing the supply voltage with the set threshold voltage. When the supply voltage falls below the threshold, the reset output is activated, indicating a power failure or low voltage condition.
