TPS2082DR

Product Overview

Category

The TPS2082DR belongs to the category of integrated circuits (ICs).

Use

It is primarily used as a power distribution switch.

Characteristics

  • The TPS2082DR is a high-side power switch.
  • It has a low on-resistance and low quiescent current.
  • It offers overcurrent protection and thermal shutdown features.

Package

The TPS2082DR is available in a small outline package (SOP) with eight pins.

Essence

The essence of the TPS2082DR lies in its ability to provide efficient power distribution and protection in various electronic systems.

Packaging/Quantity

The TPS2082DR is typically sold in reels, with each reel containing a specific quantity of ICs. The exact quantity may vary depending on the manufacturer or supplier.

Specifications

  • Input Voltage Range: 2.7V to 5.5V

  • On-Resistance: 70mΩ (typical)
  • Quiescent Current: 1µA (typical)
  • Operating Temperature Range: -40°C to +85°C

Detailed Pin Configuration

The TPS2082DR has the following pin configuration:

  1. EN (Enable): Enable control pin for turning the power switch on/off.
  2. IN (Input): Power supply input pin.
  3. OUT (Output): Power supply output pin.
  4. GND (Ground): Ground reference pin.
  5. FAULT (Fault Indicator): Pin for indicating fault conditions.
  6. ILIM (Current Limit): Pin for setting the current limit threshold.
  7. PG (Power Good): Output pin indicating that the output voltage is within the acceptable range.
  8. VCC (Supply Voltage): Supply voltage input pin.

Functional Features

  • Overcurrent Protection: The TPS2082DR incorporates overcurrent protection, which helps prevent damage to the circuit by limiting the current flow.
  • Thermal Shutdown: In case of excessive temperature, the TPS2082DR automatically shuts down to protect itself and the connected devices.
  • Enable Control: The EN pin allows for easy on/off control of the power switch.
  • Fault Indicator: The FAULT pin provides an indication when a fault condition occurs, helping in troubleshooting and system diagnostics.
  • Power Good Output: The PG pin indicates whether the output voltage is within the acceptable range, ensuring proper functioning of downstream components.

Advantages and Disadvantages

Advantages

  • Low on-resistance minimizes power loss and improves efficiency.
  • Wide input voltage range allows for compatibility with various power sources.
  • Integrated overcurrent protection and thermal shutdown enhance system reliability.
  • Enable control simplifies power management.

Disadvantages

  • Limited maximum continuous current may restrict its use in high-power applications.
  • The small outline package (SOP) may require additional precautions during soldering and handling.

Working Principles

The TPS2082DR operates as a high-side power switch. When the enable (EN) pin is activated, it allows the flow of current from the input (IN) pin to the output (OUT) pin. The integrated circuit monitors the current flowing through it and activates the overcurrent protection if the current exceeds the set threshold. Additionally, the thermal shutdown feature safeguards the device and the connected components by disabling the power switch when the temperature rises above a certain limit.

Detailed Application Field Plans

The TPS2082DR finds applications in various electronic systems, including but not limited to: - Portable devices such as smartphones, tablets, and portable gaming consoles. - USB-powered devices like external hard drives, charging docks, and audio interfaces. - Industrial automation systems requiring reliable power distribution and protection. - Automotive electronics for power management and control.

Detailed and Complete Alternative Models

Some alternative models to the TPS2082DR that offer similar functionality include: - TPS2065D: High-side power switch with adjustable current limit and fault reporting. - TPS22920: Load switch with integrated reverse voltage protection and low quiescent current. - TPS2041B: Power distribution switch with controlled rise time and undervoltage lockout.

These alternative models can be considered based on specific requirements and system constraints.
