ISL28005

Micropower, Rail-to-Rail Input Current Sense Amplifier with Voltage Output

The ISL28005 is a micropower, unidirectional

high-side and low-side current sense amplifier

Features

▪ Low Power Consumption: 50µA,Typical

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.

▪ Supply Range: 2.7V to 28V

▪ Wide Common Mode Input: 0V to 28V

▪ Fixed Gain Versions

• ISL28005-100: 100V/V

• ISL28005-50: 50V/V

• ISL28005-20: 20V/V

▪ Operating Temperature Range: -40°C to +125°C

▪ Package: 5 Ld SOT-23

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.
