Overview
The TPS22810DBVR is a single-channel load switch designed by Texas Instruments. It features an integrated N-channel MOSFET that operates over an input voltage range of 2.7 V to 18 V. This device is available in two package options: SOT23-6 (DBV) and WSON (DRV), supporting maximum continuous currents of 2 A and 3 A, respectively. The TPS22810DBVR includes several key features such as thermal shutdown, undervoltage lock-out (UVLO), and adjustable quick output discharge (QOD), ensuring safe and reliable operation. The device is controlled by an on/off input that can interface directly with low-voltage control signals, making it versatile for various applications.
