    Low offset high-side current monitor
    The ZXCT1021 is a precision high-side current
    sense monitor. Using this type of device
    eliminates the need to disrupt the ground
    plane when sensing a load current. giving better tolerances for small sense
    resistors necessary at higher currents.
    The wide input voltage range of 20V down to as
    low as 2.5V make it suitable for a range of
    applications. With a minimum operating
    current of just 25ВµA, combined with its SOT235 package make it suitable for portable battery
    equipment too. The ZXCT1021 provides a fixed gain of 10 for
    applications where minimal sense voltage is
    The very low offset voltage enables a typical
    accuracy of 3% for sense voltages of only 10mV, Features Applications Accurate high-side current sensing Battery chargers Output voltage scaling Smart battery packs 2.5V – 20V supply range DC motor control 25␮A quiescent current Over current monitor 1% typical accuracy Power management SOT23-5 package Level translating Programmable current source Pinout information
