HYCA-01 is residual current operated protective sensor for EV charger.It’s to avoid hazardous situations in cases where the vehicle battery (DC) is connected to the home power supply (AC). Generally, AC/DC sensitive residual current sensors can be used where direct current and alternating current and alternating current circuits are directly connected and therefore AC/DC leakage currents can occur.

Pin number | Symbol | Pin typ | Functions |
1 | Error | / | Open-collector output pin for indicating the system fault condition. When no system fault, this pin will be conducted to GND. When system fault occured, this pin will be highimpedance. |
2 | TEST-IN | OUTPUT | When this pin been conducted to 0VDC, module will calculate the zero-point-drift and store the value to register in the MCU to finish the callbration operation. After calibration finished, system will internally generate simulated residual current, to check whether module can do the correct response.During this procedure, X30-OUT & X6-OUT will turn to highimpedance if module working correct. Attention: When using the TEST-IN function, the main circuit must be cut-off to ensure no r esidual current flow When using this pin function, please follow the time diagram figure. |
3 | X6-OUT | OUTPUT | If residual current exceeds pre-set DC trippling value(for this module typically 4.6 mADC),this output is in a high-impedance state When the total residual current r.m.s exceeds pre-set all-current trippling value, this output is in a highimpedance state When system-fault happens, this output is in a highimpedance state. For other normal conditions, this output is in a low level(GND) |
4 | X30-OUT | OUTPUT | If residual current exceeds pre-set all-current tripping value (for pure-AC typically 23 mAAC), this output is in a high-impedance state. When system-fault happens, this output is in a highimpedance state. For other normal conditions, this output is in a low level(GND) |
5 | GND | POWER | Ground |
6 | VDD | POWER | Module power supply, standard voltage 5VDC Voltage input required to be within 4.85~5.15VDC, power output capability > 100mA Power supply ripple ÿ 150mV (It is suggested to use LDO circuit, for reference IC LP2985A-50DB) |
7 | PWM | OUTPUT | Indicating DC residual current component with duty-cycle with 8kHz PWM Output resolution = 3.33%/mADC from 0~30mADC Accuracy about ±0.5mA |
