Micropower, Rail to Rail Input Current Sense Amplifier with  
Voltage Output  
ISL28006  
Features  
The ISL28006 is a micropower, uni-directional high-side and  
low-side current sense amplifier featuring a proprietary  
rail-to-rail input current sensing amplifier. The ISL28006 is  
ideal for high-side current sense applications where the sense  
voltage is usually much higher than the amplifier supply  
voltage. The device can be used to sense voltages as high as  
28V when operating from a supply voltage as low as 2.7V. The  
micropower ISL28006 consumes only 50µA of supply current  
when operating from a 2.7V to 28V supply.

The ISL28006 features a common-mode input voltage range  
from 0V to 28V. The proprietary architecture extends the input  
voltage sensing range down to 0V, making it an excellent  
choice for low-side ground sensing applications. The benefit of  
this architecture is that a high degree of total output accuracy  
is maintained over the entire 0V to 28V common mode input  
voltage range.

• Battery Management/Charging  
• Automotive Power Distribution  
The ISL28006 is available in fixed (100V/V, 50V/V, 20V/V and  
Adjustable) gains in the space saving 5 Ld SOT-23 package  
and the 6 Ld SOT-23 package for the adjustable gain part. The  
parts operate over the extended temperature range from  
-40°C to +125°C.
