Micropower, Rail-to-Rail Input Current Sense Amplifier  
with Voltage Output  
ISL28005  
Features  
The ISL28005 is a micropower, uni-directional high-side and low-  
side current sense amplifier featuring a proprietary rail-to-rail  
input current sensing amplifier. The ISL28005 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  
ISL28005 consumes only 50µA of supply current when operating  
from a 2.7V to 28V supply.

The ISL28005 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.  
Applications  
• Power Management/Monitors  
• Power Distribution and Safety  
• DC/DC, AC/DC Converters  
• Battery Management /Charging  
• Automotive Power Distribution  
The ISL28005 is available in fixed (100V/V, 50V/V and 20V/V)  
gains in the space saving 5 Ld SOT-23 package. The parts  
operate over the extended temperature range from -40°C to  
+125°C.
