Ultra-Small µMAX Package—Only 1.11mm High  
2.7V to 5.5V Input Range  
The MAX891L/MAX892L smart, low-voltage, P-channel,  
MOSFET power switches are intended for high-side  
load-switching applications. These switches operate  
with inputs from 2.7V to 5.5V, making them ideal for  
both 3V and 5V systems. Internal current-limiting circuitry  
protects the input supply against overload. Thermal-  
overload protection limits power dissipation and junc-  
tion temperatures.  
Programmable Current Limit  
Low 13µA Quiescent Current at V = 3.3V,

0.1µA Switch Off  
Thermal Shutdown  
The MAX891L/MAX892L’s maximum current limits are  
500mA a nd 250mA, re s p e c tive ly. The c urre nt limit  
through the switch is programmed with a resistor from  
SET to ground. When the switch is on, the quiescent  
supply current is a low 13µA. When the switch is off, the  
quiescent current decreases to 0.1µA.
