• Overcurrent and thermal protection safeguards the device and connected components

Disadvantages

• Limited maximum continuous current may restrict usage in high-power applications
• Temperature range may not be suitable for extreme environments

Working Principles

The TPS22975NDSGR operates by controlling the flow of power from the input voltage (VIN) to the output voltage (VOUT) based on the enable pin (EN) signal. When the enable pin is high, the switch node (SW) connects VIN to VOUT, allowing power to flow through. Conversely, when the enable pin is low, the switch node disconnects VIN from VOUT, cutting off the power supply.

Detailed Application Field Plans

The TPS22975NDSGR finds application in a wide range of electronic devices, including but not limited to: - Mobile phones - Tablets - Portable gaming consoles - Wearable devices - IoT devices

In these applications, it can be used for load switching, power sequencing, and power management tasks.
