Overview
The TPS2301IPWR is a dual-channel hot-swap controller produced by Texas Instruments. This device is designed to manage power in hot-swap applications, utilizing external N-channel MOSFETs as high-side switches. It features independent overcurrent protection (OCP), inrush current control, and power-good reporting, making it suitable for critical power management tasks. The controller includes undervoltage lockout (UVLO) and power-good (PG) reporting to ensure reliable operation and status indication of the output voltage rails.
