DESCRIPTION
The SiP4280A is a P-Channel MOSFET power switch
designed for high-side load switching applications. The
output pass transistor is a P-Channel MOSFET tran-
Both SiP4280A load switch versions operate with an
input voltage ranging from 1.5 V to 5.5 V, making them
ideal for both 3 V and 5 V applications. The SiP4280A
also features an under-voltage lock out which turns the
switch off when an input undervoltage condition exists.
Input logic levels are TTL and 2.5 V to 5.0 V CMOS
compatible. The quiescent supply current is very low,
typically 25 nA. In shutdown mode, the supply current
decreases to less than 1.0 µA.
sistor with typically 80 mΩ R
. The SiP4280A is
DS(ON)
available in two different versions of turn-on times. The
SiP4280A-1 version has a slew rate limited turn-on
time typically of 1 ms. The SiP4280A-3 version has a
slew rate limited turn-on time typically of 100 µs and
additionally offers a shutdown load discharge circuit to
rapidly turn off a load circuit when the switch is dis-
abled.
The SiP4280A is available in a 6 pin SOT23 package
and is specified over - 40 °C to 85 °C temperature
range.

DETAILED DESCRIPTION
The SiP4280A is a P-Channel MOSFET power
switches designed for high-side slew rate controlled
load switching applications. Once turned on, the slew-
rate control circuitry is activated and current is ramped
in a linear fashion until it reaches the level required for
the output load condition. This is accomplished by first
elevating the gate voltage of the MOSFET up to its
threshold voltage and then by linearly increasing the
gate voltage until the MOSFET becomes fully
enhanced. At this point, the gate voltage is then
quickly increased to the full input voltage to reduce
The SiP4280A-1 version has a modest 1 ms turn on
slew rate feature, which significantly reduces in-rush
current at turned on time and permits the load switch
to be implemented with a small input capacitor, or no
input capacitor at all, saving cost and space. In addi-
tion to a 100 µs minimized slew rate, the SIP4280A-3
features a shutdown output discharge circuit which is
activated at shutdown (when the part is disabled
through the ON/OFF pin) and discharges the output
pin through a small internal resistor hence, turning off
the load.

table. However, The real limiting factor for the safe
operating load current is the thermal power dissipation
of the package. To obtain the highest power dissipa-
tion the power pad of the device should be connected
to a heat sink on the printed circuit board.
Input Capacitor
While a bypass capacitor on the input is not required,
a 1 µF or larger capacitor for C is recommended in
IN
almost all applications. The Bypass capacitor should
be placed as physically close as possible to the
SiP4280A to be effective in minimizing transients on
the input. Ceramic capacitors are recommended over
tantalum because of their ability to withstand input
current surges from low impedance sources such as
batteries in portable devices.
The maximum power dissipation in any application is
dependant on the maximum junction temperature,
T
= 125 °C, the junction-to-ambient thermal
J(MAX)
resistance θJ-A = 180 °C for SOT23-6, and the ambient
temperature, T , which may be formulaically

It then follows that, assuming an ambient temperature
of 70 °C, the maximum power dissipation will be limited
to about 305 mW for SOT23-6.
