TPS2557DRBR TI Power Distribution Switches, Load Drivers
The TPS2557 is a 5.5V, 2.5A precision adjustable current-limited power-distribution switch, operating from a 2.5V to 6.5V input. It features accurate current limit (0.5A to 2.5A), reverse voltage protection, and overcurrent fault reporting. The device includes thermal shutdown with auto-retry and undervoltage lockout. Packaged in an 8-pin SON (DRB) (3mm × 3mm) with PowerPAD, it is ideal for USB port protection and hot-swap applications. Applications include USB downstream ports on computers, power muxing in portable electronics, and power-sequencing circuits. In stock at HL Electronics – request a quote for fast delivery.
