TPS2043DR

Product Overview

Category

The TPS2043DR belongs to the category of power distribution switches.

Use

It is primarily used for controlling the distribution of power in electronic circuits.

Characteristics

  • High efficiency
  • Low power consumption
  • Overcurrent protection
  • Thermal shutdown protection
  • Fast response time

Package

The TPS2043DR comes in a small outline package (SOP) with eight pins.

Essence

The essence of the TPS2043DR lies in its ability to efficiently control and protect power distribution in electronic circuits.

Packaging/Quantity

The TPS2043DR is typically packaged in reels or tubes, with a quantity of 2500 units per reel/tube.

Specifications

  • Input voltage range: 2.7V to 5.5V
  • Output voltage range: 0V to VCC
  • Maximum continuous current: 500mA
  • Operating temperature range: -40°C to 85°C

Detailed Pin Configuration

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

Functional Features

  • Overcurrent protection: Automatically shuts off the switch when the current exceeds the specified limit.
  • Thermal shutdown protection: Prevents damage due to excessive heat by disabling the switch temporarily.
  • Fast response time: Ensures quick reaction to fault conditions, minimizing potential damage to the circuit.

Advantages and Disadvantages

Advantages

  • Efficient power distribution control
  • Reliable overcurrent and thermal protection
  • Compact package size
  • Wide input voltage range

Disadvantages

  • Limited maximum continuous current capacity (500mA)
