SiP4282A  
Vishay Siliconix  
1.2 A Slew Rate Controlled Load Switch in PPAK SC75-6  
FEATURES  
DESCRIPTION  
•
•
1.5 V to 5.5 V Input Voltage range  
Very Low RDS(ON), typically 140 mW  
at 5 V and 175 mW at 3 V  
The SiP4282A is a P-Channel MOSFET power switch IC  
designed for high-side load switching applications. The  
output switching transistor is a P-Channel MOSFET device  
that has a 140 mΩ RDS(ON) typically to increase load  
switching power handling capacity. The SiP4282A is  
available in two different versions with turn-on and turn-off  
characteristics ranging from very fast to slew rate limited. In  
addition to a fast turn-off time of 4 µs, the SiP4282A-3  
RoHS  
COMPLIANT  
•
Slew rate limited turn-on time options  
- SiP4282A-1: 1 ms  
- SiP4282A-3: 100 µs  
•
•
•
•
•
Fast shutdown load discharge option  
Low quiescent current, typically 25 nA  
Low Shutdown Current < 1 µA  
TTL/CMOS input logic level  
SC-75 Package  
version offers  
a shutdown load discharge circuit to  
instantaneously turn off a load circuit when the switch is  
disabled.  
The SiP4282A load switch operates with an input voltage  
ranging from 1.5 V to 5.5 V, making it ideal for both 3 V and  
5 V systems. The SiP4282A 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 V CMOS compatible. This device has a very low  
operating current (typically 25 nA), making it ideal for battery-  
powered applications. In shutdown mode, the supply current  
de-creases to less than 1 µA.

DETAILED DESCRIPTION  
APPLICATION INFORMATION  
Input Capacitor  
The SiP4282A 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.  
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 SiP4282A 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.  
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 SiP4282A turn on  
slew rate time. There are no ESR or capacitor type  
requirement.  
The SiP4282A-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 addition to a 100 µs minimized slew rate,  
the SIP4282A-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.  
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.  
Enable  
The ON/OFF pin is compatible with both TTL and CMOS  
logic voltage levels.

It then follows that, assuming an ambient temperature of  
70 °C, the maximum power dissipation will be limited to about  
610 mW.  
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.  
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  
In conditions where VOUT exceeds VIN a Schottky diode in  
parallel with the internal intrinsic diode is recommended to  
protect the SiP4282A.  
Thermal Considerations  
The SiP4282A 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 ABS MAX 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.  
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  
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  
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:  
P (max)  
I
(max) 〈

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.
