Description
The Texas Instruments TPS22961DNYR is a power switch/driver that integrates a single-channel load switch with an N-channel MOSFET. It's designed for low-voltage applications, operating from a VBIAS voltage range of 3V to 5.5V and input voltage range of 0.8V to 3.5V.
This device features ultra-low RON resistance (4.4mΩ at VIN = 1.05V), making it suitable for high-current applications up to 6A continuous. It also has a low quiescent current (<1µA) and controlled slew rate, which helps reduce electromagnetic interference (EMI).
The TPS22961DNYR is available in an 8-pin WSON package with a thermal pad, making it suitable for surface-mount technology (SMT) applications. Its ESD performance has been tested per JESD 22 standards, ensuring reliable operation in harsh environments.
This device is ideal for powering small loads, such as LEDs or sensors, and can be used in various applications like industrial control systems, automotive electronics, and consumer devices.
