TPS25921ADR TI Current Regulation/Management

The TPS25921A is a 4.5-V to 18-V eFuse with integrated 27-mΩ FET, providing precise current limit and overvoltage protection . It features programmable current limit from 0.2-A to 1.8-A, adjustable output slew rate, and overvoltage clamp at 5.8-V or external programmable thresholds. The device includes undervoltage lockout (UVLO), reverse current blocking, and thermal shutdown with auto-retry. Packaged in an 8-pin SOIC (D), it is ideal for hot-swap protection, power distribution, and USB port protection. Applications include PCIe, SSDs, set-top boxes, and industrial equipment requiring robust circuit protection with precise current limiting.
