  • Output voltage range: 0V to Vcc
  • Maximum continuous current: 500mA
  • Operating temperature range: -40°C to 85°C

Pin Configuration

The TPS2044ADRG4 has the following pin configuration:

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

Functional Features

  • Overcurrent protection: The TPS2044ADRG4 monitors the output current and shuts off the switch if it exceeds a certain threshold.
  • Thermal shutdown protection: In case of excessive temperature, the device automatically shuts down to prevent damage.
  • Fast response time: The switch responds quickly to changes in input voltage or load conditions.
  • Low quiescent current: When the switch is in the off state, it consumes minimal current, conserving power.

Advantages and Disadvantages

Advantages

  • Efficient power distribution
  • Overcurrent and thermal protection
  • Small package size
  • Low quiescent current

Disadvantages

  • Limited maximum continuous current (500mA)
  • Restricted input voltage range (2.7V to 5.5V)

Working Principles

The TPS2044ADRG4 operates by controlling the flow of current between the input and output pins. When the enable pin is high, the switch is turned on, allowing current to flow from the input to the output. If the current exceeds a certain threshold or the temperature rises above a specified limit, the switch automatically shuts off to protect the circuit.
