SG Micro SGM8193
Tiny packages, nano-power, precision current-sense amplifier
The SGM8193 series is a nano-power, high precision, high-side current-sense amplifier. The device can sense the voltage across a current-sense resistor in a common mode voltage range from 1.6V to 28V. The SGM8193 series provides four fixed gains: 25V/V, 50V/V, 100V/V and 200V/V, which allows flexible selection of the external current-sense resistor.
The SGM8193 is available in Green SOT-23-5 and WLCSP-1×1-4B packages. The tiny packages make the device an excellent choice for portable and battery- powered applications, where the size is limited.
