• Manufacturer Part Number: ZXCT1023_0910
• Description: MICROPOWER FIXED GAIN OF 50 CURRENT MONITOR
• Manufacturer: DIODES [Diodes Incorporated]

Application information
The ZXCT1023 is line powered (derives its power from the rail being sensed) this reduces the number of pins used and
PCB trace routing. The fixed gain of 50 reduces the PCB area by reducing the number of external components. The only
external component required is the sense resistor. This coupled with the 1.2mm x 1.8mm TDFN package makes the
solution size very small.
The fixed gain of 50 has been chosen to meet the normal requirements of most applications.
The ZXCT1023 has its gain setting resistor, R
Application Examples
Please refer to Zetex AN39 for sample applications.
