Overview
ZXCT1021 Low offset high-side current monitor Description 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.
The ZXCT1021 provides a fixed gain of 10 for applications where minimal sense voltage is required.
The very low offset voltage enables a typical accuracy of 3% for sense voltages of only 10mV, Features • Accurate high-side current sensing 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 25µA, combined with its SOT235 package make it suitable for portable battery equipment too.
Applications • 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 managem...
