Package

The TPS259521DSGT is available in a small surface-mount package, commonly known as DSGT. This package ensures easy integration into circuit boards and provides mechanical stability.

Essence

The essence of the TPS259521DSGT lies in its ability to protect electronic devices from potential damage caused by excessive voltage or current.

Packaging/Quantity

The TPS259521DSGT is typically packaged in reels or tubes, containing a specific quantity of units per package. The exact packaging and quantity may vary depending on the supplier.

Specifications

  • Input Voltage Range: 2.7V to 18V
  • Operating Temperature Range: -40°C to +85°C
  • Quiescent Current: 10µA (typical)
  • Overvoltage Threshold: Adjustable from 2.8V to 18V
  • Overcurrent Threshold: Adjustable from 0.1A to 5A
  • Response Time: <1µs

Detailed Pin Configuration

The TPS259521DSGT features the following pin configuration:

  1. EN (Enable): Controls the device's operation.
  2. IN (Input): Connects to the power source.
  3. OUT (Output): Connects to the load.
  4. GND (Ground): Provides the reference potential for the device.

Functional Features

  • Overvoltage Protection: Monitors the input voltage and disconnects the load when it exceeds the set threshold.
  • Overcurrent Protection: Monitors the load current and disconnects the load when it exceeds the set threshold.
  • Fast Response Time: Ensures quick protection activation to prevent damage to the load.

Advantages and Disadvantages

Advantages

  • Reliable overvoltage and overcurrent protection
  • Low power consumption
  • Compact package for easy integration
