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. 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
required.
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
