Hello, Welcome to Dasenic

The TPS22966DPUR is a load switch that enables or disables a power path to a load. It is designed to support a maximum continuous current of 2 A and can handle input voltages ranging from 1.2 V to 5.5 V. It features a low on-resistance and provides a controlled turn-on of the load, minimizing inrush current during switching events. Functions: - Load Switching: It allows for turning on and off the power to the load seamlessly. - Controlled Rise Time: The IC provides a controlled rise time to reduce inrush current and ensure stable operation. - Enable Input: It has an enable pin that controls the operation of the switch. - Current Limiting: The device provides over-current protection features to prevent damage to the load and the IC itself. - Thermal Protection: Inbuilt thermal shutdown capability ensures the device operates safely under high-temperature conditions. Applications: - Power Management: Used in power distribution for CPUs, GPUs, and FPGAs. - Battery-Powered Devices: Provides efficient load control to preserve battery life. - Consumer Electronics: Commonly utilized in smartphones, tablets, and other portable devices. - Networking Equipment: Suitable for load switching in routers and switches. Alternative Parts: - TPS22915: A similar load switch designed for lower current applications. - TPS22917: Provides higher current capacity and additional features like reverse current blocking. - BTS7002-1: A high-side switch which may be used in similar applications but may have different characteristics. Embedded Modules: While the TPS22966DPUR is typically used as a standalone IC, it can be integrated into larger systems or evaluation modules from Texas Instruments to facilitate easy evaluation and integration into designs.
