  • Output voltage range: 0V to VIN
  • Continuous output current: Up to 500mA
  • Quiescent current: 20µA (typical)
  • Operating temperature range: -40°C to 85°C

Pin Configuration

The TPS2047DR has the following pin configuration:

  1. EN (Enable)
  2. IN (Input)
  3. GND (Ground)
  4. OUT (Output)
  5. FLT (Fault)
  6. NC (No Connection)
  7. NC (No Connection)
  8. VCC (Supply Voltage)

Functional Features

  • Overcurrent protection: The TPS2047DR monitors the output current and shuts off the switch if it exceeds a certain threshold.
  • Thermal shutdown protection: It includes a built-in thermal shutdown feature that protects the device from overheating.
  • Enable control: The EN pin allows for easy on/off control of the power switch.
  • Fast response time: The TPS2047DR provides quick response times to ensure efficient power distribution.

Advantages and Disadvantages

Advantages

  • High efficiency leads to reduced power consumption.
  • Overcurrent and thermal shutdown protection enhance system reliability.
  • Enable control allows for easy integration into existing circuits.
  • Fast response time ensures efficient power distribution.

Disadvantages

  • Limited output current capacity (up to 500mA).
  • Restricted input voltage range (2.7V to 5.5V).

Working Principles

The TPS2047DR operates by monitoring the output current and comparing it to a predefined threshold. If the current exceeds this threshold, the switch is turned off to protect the circuit from damage. Additionally, the device includes a thermal shutdown feature that activates when the temperature exceeds a certain limit, preventing overheating.
