and TDFN4 1.2 mm x 1.6 mm
FEATURES
DESCRIPTION
•
1.8 V to 5.5 V input voltage range for SiP4282
1.5 V to 5.5 V input voltage range for
SiP4282A
The SiP4282 series is a slew rate controlled high side switch.
The switch is of a low ON resistance P-Channel MOSFET
that supports continuous current up to 1.2 A.
•
The SiP4282 series operates with an input voltage from
1.8 V to 5.5 V. It offers under voltage lock out that turns the
switch off when an input under voltage condition exists. The
"A" option without UVLO extends the minimum operation
voltage from 1.8 V down to 1.5 V. The SiP4282 is available in
two different versions of slew rates, 100 µs and 1 ms. The
SiP4282 series integrates load discharge circuit to ensure
the discharge of capacitive load when the switch is disabled.
The SiP4282 features low input logic level to interface with
low control voltage from microprocessors. This device has a
very low operating current (typically 2.5 µA for SiP4282 and
50 pA for SiP4282A).
The SiP4282 is available in lead (Pb)-free package options
including 6 pin PPAK SC75-6, and 4 pin TDFN4 1.2 mm x
1.6 mm DFN4 packages. The operation temperature range
is specified from - 40 °C to + 85 °C.
The SiP4282 compact package options, operation voltage
range, and low operating current make it a good fit for battery
power applications.

SiP4282
Vishay Siliconix
In conditions where VOUT exceeds VIN a Schottky diode in
parallel with the internal intrinsic diode is recommended to
protect the SiP4282.
DETAILED DESCRIPTION
The SiP4282 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 RDS(ON) of the
MOSFET switch and minimize any associated power losses.
Thermal Considerations
The SiP4282 is designed to maintain a constant output load
current. Due to physical limitations of the layout and
assembly of the device the maximum switch current is 1.2 A,
as stated in the Absolute Maximum Ratings table. However,
another limiting characteristic for the safe operating load
current is the thermal power dissipation of the package. To
obtain the highest power dissipation (and a thermal
resistance of 90 °C/W) the power pad of the device should
be connected to a heat sink on the printed circuit board.
The maximum power dissipation in any application is
dependant on the maximum junction temperature,
TJ(MAX) = 125 °C, the junction-to-ambient thermal resistance
for the SC-75 PPAK package, θJ-A = 90 °C/W, and the
ambient temperature, TA, which may be formulaically
expressed as:
The SiP4282A-2 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. All versions features a shutdown output dis-
charge 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.
For SiP4282-3, in instances where the input voltage falls
below 1.4 V (typically) the under voltage lock-out circuitry
protects the MOSFET switch from entering the saturation
region or operation by shutting down the chip.

J- A
It then follows that, assuming an ambient temperature of
70 °C, the maximum power dissipation will be limited to about
610 mW.
So long as the load current is below the 1.2 A limit, the
maximum continuous switch current becomes a function two
things: the package power dissipation and the RDS(ON) at the
ambient temperature.
As an example let us calculate the worst case maximum load
current at TA = 70 °C. The worst case RDS(ON) at 25 °C
occurs at an input voltage of 1.8 V and is equal to 480 mΩ.
The RDS(ON) at 70 °C can be extrapolated from this data
using the following formula
APPLICATION INFORMATION
Input Capacitor
While a bypass capacitor on the input is not required, a 1 µF
or larger capacitor for CIN is recommended in almost all
applications. The bypass capacitor should be placed as
physically close as possible to the SiP4282 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.
RDS(ON) (at 70 °C) = RDS(ON) (at 25 °C) x (1 + TC x ΔT)
Where TC is 3300 ppm/°C. Continuing with the calculation
we have
Output Capacitor
A 0.1 µF capacitor or larger across VOUT and GND is
recommended to insure proper slew operation. COUT may be
increased without limit to accommodate any load transient
condition with only minimal affect on the SiP4282 turn on
slew rate time. There are no ESR or capacitor type
requirement.
RDS(ON) (at 70 °C) = 480 mΩ x (1 + 0.0033 x (70 °C - 25 °C))
= 551 mΩ
The maximum current limit is then determined by

which in case is 1.05 A. Under the stated input voltage
condition, if the 1.05 A current limit is exceeded the internal
die temperature will rise and eventually, possibly damage the
device.
Protection Against Reverse Voltage Condition
The P-channel MOSFET pass transistor has an intrinsic
diode that is reversed biased when the input voltage is
greater than the output voltage. Should VOUT exceed VIN,
this intrinsic diode will become forward biased and allow
excessive current to flow into the IC thru the VOUT pin and
potentially damage the IC device. Therefore extreme care
should be taken to prevent VOUT from exceeding VIN.
