TPS2306DW

Hot Swap Controllers Overview

The TPS2306DW is a dual sequencing hot swap power manager manufactured by Texas Instruments. It integrates two independent channels for controlled power-up and power-down sequences in multi-rail systems. The device supports input voltages up to 15V and provides precise current limiting and soft-start capabilities. Packaged in a 16-pin SOIC (DW) surface-mount case, it ensures safe insertion into live backplanes without causing voltage droops or system resets.
