TPS2831DR

Product Overview

Category

The TPS2831DR belongs to the category of integrated circuits (ICs).

Use

It is primarily used as a high-speed, dual-channel power distribution switch.

Characteristics

  • High-speed switching capability
  • Dual-channel design
  • Low on-resistance
  • Overcurrent protection
  • Thermal shutdown protection

Package

The TPS2831DR is available in a small outline package (SOP) with eight pins.

Essence

The essence of the TPS2831DR lies in its ability to efficiently control and distribute power in electronic systems.

Packaging/Quantity

The TPS2831DR is typically packaged in reels or tubes and is available in various quantities depending on the manufacturer's specifications.

Specifications

  • Input voltage range: 2.7V to 5.5V
  • Maximum continuous current per channel: 1.5A
  • On-resistance per channel: 50mΩ
  • Operating temperature range: -40°C to +85°C

Detailed Pin Configuration

The TPS2831DR has the following pin configuration:

  1. EN1 (Enable Input Channel 1)
  2. IN1 (Input Channel 1)
  3. OUT1 (Output Channel 1)
  4. GND (Ground)
  5. OUT2 (Output Channel 2)
  6. IN2 (Input Channel 2)
  7. EN2 (Enable Input Channel 2)
  8. VCC (Supply Voltage)

Functional Features

  • Independent enable inputs for each channel
  • Fast turn-on and turn-off times
  • Low quiescent current
  • Fault reporting through status flag
  • Reverse current blocking

Advantages and Disadvantages

Advantages

  • High-speed switching capability allows for efficient power distribution
  • Dual-channel design provides flexibility in system design
  • Low on-resistance minimizes power loss
  • Overcurrent and thermal shutdown protection enhance system reliability

Disadvantages

  • Limited maximum continuous current per channel (1.5A)
  • Operating temperature range may not be suitable for extreme environments

Working Principles

The TPS2831DR operates by controlling the flow of current between its input and output channels. When the enable input is high, the switch is turned on, allowing current to flow from the input to the output. Conversely, when the enable input is low, the switch is turned off, blocking the current flow.
