WCS2702 for overcurrent detection and short circuit detection
With Analog and digital signals Current Rang:0-2A  1V/1A

Part No：WCS2702 Current Sensor module
Primary Sampled Current  Ia: 0A-2A
Sensitivity K :2V/A
Supply VCC:3V or 5.5V;
Analog Signals：
(1)If the Current is AC
Analog Signals Formula：
Aout =VCC/2+Ia*K   -----  Ia=+(Aout-Vcc/2)/K=+ (Aout-2.5V) /1  ( if VCC=5V);
(2)If the Current is DC
Analog Signals Formula：
Aout =VCC/2+Ia*K   -----  Ia=(Aout-Vcc/2)/K=(Aout-2.5V) /1  ( if VCC=5V);
(Primary sampled current Ia should be within the range specified);
