DESCRIPTION
The SiP4280 is a P-Channel MOSFET power switch
designed for high-side load switching applications.
The output pass transistor is a P-Channel MOSFET
transistor with typically 80 mΩ R
DS(ON)
. The SiP4280
is available in two different versions of turn-on times.
The SiP4280-1 version has a slew rate limited turn-on
time typically of 1 ms. The SiP4280-3 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.
Both SiP4280 load switch versions operate with an
input voltage ranging from 1.8 V to 5.5 V, making them
ideal for both 3 V and 5 V applications. The SiP4280
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 2.5 µA. In shutdown mode, the sup-
ply current decreases to less than 1.0 µA.
The SiP4280 is available in a 6 pin SOT23 package
and is specified over - 40 °C to 85 °C temperature
range
.

Notes:
a. Device mounted with all leads soldered or welded to PC board.
b. Derate 5.5 mW/°C above T
A
= 70 °C.
Stresses beyond those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. These are stress ratings only,
and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is
not implied. Exposure to absolute maximum rating/conditions for extended periods may affect device reliability.
Notes:
a. The algebraic convention whereby the most negative value is a minimum and the most positive a maximum.
b. Typical values are for DESIGN AID ONLY, not guaranteed nor subject to production testing.
c. Part requires minimum start-up of V
IN
≥ 2.0 to ensure operation down to 1.8 V.
d. For V
IN
≤ 2.7 V see typical ON/OFF threshold curve.
