Detailed Pin Configuration

The TC646BEPA has the following pin configuration:

  1. GND (Ground)
  2. RESET (Active-Low Reset Output)
  3. VCC (Positive Supply Voltage)
  4. MR (Manual Reset Input)
  5. TH (Threshold Voltage Selection)
  6. TR (Reset Timeout Period Selection)
  7. CT (External Capacitor Connection)
  8. NC (No Connect)

Functional Features

  • Monitors the supply voltage and provides a reset signal when it falls below a specified threshold.
  • Offers manual reset capability through the MR pin.
  • Allows selection of threshold voltage and reset timeout period through dedicated pins.
  • Provides an active-low reset output for interfacing with other devices.

Advantages and Disadvantages

Advantages: - High precision voltage monitoring. - Low power consumption. - Wide operating temperature range. - Flexible threshold voltage and reset timeout period options.

Disadvantages: - Limited number of threshold voltage options. - No internal pull-up resistor on the MR pin.

Working Principles

The TC646BEPA operates by continuously monitoring the supply voltage using an internal voltage reference. When the supply voltage drops below the selected threshold voltage, the reset output is activated, indicating a power failure or low voltage condition. The reset signal remains active until the supply voltage rises above the threshold and the reset timeout period elapses.

Detailed Application Field Plans

The TC646BEPA is commonly used in various applications where reliable voltage monitoring is critical. Some of the typical application fields include:

  1. Power Supply Units (PSUs)
  2. Battery-Powered Devices
  3. Microcontrollers and Microprocessors
  4. Industrial Control Systems
  5. Automotive Electronics
