MCx1101 Evaluation Note Ver1.5 Dec. 14, 2018 Page 1 of 4 DESCRIPTION The EB0013 evaluation board provides a simple way to evaluate MCx1101 family of current sensor ICs. This double sided PCB with 4-ounce copper produces the low resistance path to the galvanically isolated primary current. An 8-pin connector P1 and test points enable users to easily access the signals of the secondary side bias and outputs. Two BNC outputs (VREF and VOUT) are intended to provide the low noise channels for VREF and VOUT signals to the oscilloscope or other test equipments. FEATURES High Accuracy Current Sensor Superior Frequency Response (1.5 MHz 3dB BW) Fast output response time (300ns typical) Low Primary Resistance (0.9m /50A and 1.3m/5A/ 20A typical) 5V Single Supply Operation Low power consumption (8mA typical) Overcurrent fault detection SOIC-16 package (RoHS/REACH compliant) -40C to +105C Operating Temperature Range UL/IEC/EN60950-1 Certified 4.8 kV Dielectric Strength Voltage 1097 VRMS Basic Isolation Voltage 400 VRMS Reinforced Isolation Voltage ORDER INFORMATION EVB PART NUMBER Current Range Gain Voltage EVB MCA1101-5-5 +/-5 Amp Fixed 5V EVB MCA1101-20-5 +/-20 Amp Fixed 5V Note1 EVB MCA1101-50-5 +/-50 Amp Fixed 5V EVB MCR1101-5-5 +/-5 Amp Ratiometric 5V EVB MCR1101-20-5 +/-20 Amp Ratiometric 5V Note1 EVB MCR1101-50-5 +/-50 Amp Ratiometric 5V Note1: 50A Pluse TEST BOARD PIN DESCRIPTION Name Connection Description Fix the wire of Primary Current I IN Non-Inverting Current Sense Input by screw Fix the wire of Primary Current I OUT Inverting Current Sense Input by screw VOC P1 Connector Pin 1 Input pin.
