General Description

The TPS2556-Q1 and TPS2557-Q1 powerdistribution switches are specialized for automotive applications which require precision current limiting or capacity to handle heavy capacitive loads and short circuits.

These devices offer a programmable currentlimit threshold between 500 mA and 5 A (typical) via an external resistor.

Control of the power-switch rise and fall times minimizes current surges during turnon or turnoff.
