ZXCT1022E5TA 稳流/电流管理电源IC 电流监控器 标记SOT-153/SOT23-5 marking1022
Description
The ZXCT1022 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 ZXCT1022 provides a fixed gain of 100 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, giving better tolerances for small sense resistors necessary at higher currents.
