Brief Description

The KTS1605 is slew rate controlled load switch
designed for 1.5V to 5.5V 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 5A, whilst
minimizing the power dissipation and voltage drop
from supply to load. The KTS1605 features an active
high enable pin, which is capable of interfacing
directly with low input control signals, without any
additional level shifting circuitry. The KTS1605 also
includes an active pull-down to ensure the device
remains off, should the enable be allowed to float.
The KTS1605 provides reverse blocking in the OFF
state to ensure that power supplies are not
discharged.
In addition, the KTS1605 has an option for output
auto discharge feature. This enables the device to
quickly discharge the output when the device is
disabled.
The KTS1605 is available in an optimized, lead-free,
RoHS and Green compliant, small 6-pin WLCSP 1.0
x 1.5mm package with 0.5mm pitch
