Brief Description

The KTS1601 is slew rate controlled load switch

designed for 1.5 V to 5.5 V operation. It features a

controlled soft-on slew rate of typical 2.7ms that

limits the inrush current for designs with heavy

capacitive loads and thereby minimizing any

resulting voltage droop at the power rails.

The very low RDS(ON) allows currents up to 2.0A,

whilst minimizing the power dissipation and voltage

drop from supply to load. The KTS1601 features an

active high enable pin, which is capable of interfacing

directly with low input control signals, without any

additional level shifting circuitry. The KTS1601 also

includes an active pull-down option to ensure the

device remains off, should the enable be allowed to

float.

The KTS1601 provides reverse blocking in the OFF

state to ensure that power supplies are not

discharged.

The KTS1601 is available in an optimized, lead-free,

fully green compliant, small 4-pin WLCSP 1.0 x

1.0mm package with 0.5mm pitch
