ZXCT1020E5TA

ZXCT1020E5TA is a low offset current output current monitor. It is a precision high-side current sense monitor that eliminates the need to disrupt the ground plane when sensing a load current. It uses two external resistors to set the overall voltage gain for applications where improved accuracy at small sense voltages is required. Current output enables the user to set the gain via these external resistors. Using two external resistors to set the gain ensures optimal versatility as the transconductance can be varied to meet the output impedance requirements of the load that the ZXCT1020 has to drive. Applications include battery chargers, over-current monitors, motherboard power supply current measurement, level translating, and programmable current sources.
