  • Fast response time

Package

The TPS2044D is available in a small outline package (SOP) with 8 pins. The package provides thermal efficiency and ease of integration into various circuit designs.

Essence

The essence of the TPS2044D lies in its ability to control the power flow in electronic devices, ensuring safe operation and protecting sensitive components from damage.

Packaging/Quantity

The TPS2044D is typically packaged in reels or tubes, containing a specified quantity of ICs per package. The exact packaging and quantity may vary depending on the manufacturer.

Specifications

  • Input Voltage Range: 2.7V to 5.5V
  • Output Voltage Range: 0V to Vcc
  • Maximum Continuous Current: 500mA
  • Quiescent Current: 20µA (typical)
  • Operating Temperature Range: -40°C to +85°C

Pin Configuration

The TPS2044D has 8 pins arranged as follows:

  1. EN (Enable): Controls the power switch operation.
  2. IN (Input): Connects to the power source.
  3. GND (Ground): Common ground reference.
  4. OUT (Output): Connects to the load.
  5. FLT (Fault): Indicates fault conditions.
  6. NC (No Connection): Not connected.
  7. NC (No Connection): Not connected.
  8. Vcc (Supply Voltage): Powers the IC.

Functional Features

  1. Overcurrent Protection: The TPS2044D monitors the current flowing through the load and shuts off the power switch if it exceeds a predefined threshold, protecting the load and the power source from damage.
  2. Short-Circuit Protection: In the event of a short circuit, the TPS2044D quickly detects the fault and disables the power switch to prevent excessive current flow.
  3. Fast Response Time: The TPS2044D reacts swiftly to overcurrent and short-circuit conditions, minimizing the risk of damage to the load or other components.
  4. Low Quiescent Current: The IC consumes minimal current in standby mode, reducing power consumption and extending battery life.
  5. Wide Input Voltage Range: The TPS2044D can operate with input voltages ranging from 2.7V to 5.5V, making it compatible with various power sources.

Advantages and Disadvantages

Advantages

  • Provides reliable overcurrent and short-circuit protection.
  • Low quiescent current minimizes power consumption.
  • Wide input voltage range enhances compatibility.
  • Fast response time ensures prompt fault detection and protection.

Disadvantages

  • Limited maximum continuous current of 500mA may not be suitable for high-power applications.
  • Requires external control signal (EN pin) for operation.

Working Principles

The TPS2044D operates by monitoring the current flowing through the load. When the current exceeds a predetermined threshold, indicating an overcurrent condition, or when a short circuit is detected, the IC disables the power switch to protect the load and the power source. The EN pin controls the operation of the power switch, allowing the user to enable or disable the power flow as required.
