New Product  
SiP4282  
Vishay Siliconix  
1 A Slew Rate Controlled Load Switch in PPAK SC75-6  
FEATURES  
DESCRIPTION  
1.8 V to 5.5 V Input Voltage range  
Very Low RDS(ON), typically 140 mΩ  
at 5 V and 175 mΩ at 3 V  
Slew rate limited turn-on time options  
- SiP4282-1: 1 ms  
The SiP4282 is a P-Channel MOSFET power switch IC  
designed for high-side load switching applications. The out-  
put switching transistor is a P-Channel MOSFET device that  
has a 140 mΩ RDS(ON) typically to increase load switching  
power handling capacity. The SiP4282 is available in two dif-  
ferent versions with turn-on and turn-off characteristics rang-  
ing from very fast to slew rate limited. In addition to a fast  
turn-off time of 4 µs, the SiP4282-3 version offers a shut-  
down load discharge circuit to instantaneously turn off a load  
circuit when the switch is disabled.  
- SiP4282-3: 100 µs  
Fast shutdown load discharge option  
Low quiescent current, typically 2.5 µA  
Low Shutdown Current < 1 µA  
TTL/CMOS input logic level  
UVLO of 1.4 V  
The SiP4282 load switch operates with an input voltage  
ranging from 1.8 V to 5.5 V, making it ideal for both 3 V and  
5 V systems. The SiP4282 also features an under-voltage  
lock out which turns the switch off when an input undervolt-  
age 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 2.5 µA), making it ideal for battery-powered  
applications. In shutdown mode, the supply current  
decreases to less than 1 µA.
