The TPS2087DG4 has a total of 8 pins:
Advantages: - High current limit allows for powering demanding loads. - Overtemperature protection ensures safe operation. - Low quiescent current minimizes power consumption.
Disadvantages: - Limited input voltage range (2.7V to 5.5V). - Maximum continuous current limit may not be sufficient for certain applications.
The TPS2087DG4 is a power distribution switch that controls the flow of current from the input to the output. It utilizes a MOSFET as a power switch, which can be enabled or disabled using the EN pin. The FB pin provides feedback to regulate the output voltage. The ILIM pin sets the current limit threshold, protecting the circuit from excessive current. The SS pin controls the soft start time, gradually increasing the output voltage to prevent inrush current. The PG pin indicates when the output voltage is within regulation limits.
The TPS2087DG4 is commonly used in various applications, including:
These alternative models offer different specifications and features, allowing users to choose the most suitable option for their specific requirements.
