TPS2556 Datasheet (Texas Instruments) - Precision Adjustable Current-Limited Power-Distribution Switches

TPS2556, Precision Adjustable Current-Limited Power-Distribution Switches

The TPS255x power-distribution switch is intended for applications where precision current limiting is required or heavy capacitive loads and short circuits are encountered.

These devices offer a programmable current-limit threshold between 500 mA and 5 A (typical) through an external resistor.
