Description

Introduce

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.

Applications

DC 6mA Current Alarm.

Mounted on PCB Board.

30mA AC/6mA DC Trip Indication.

High-frequency response up to 2kHz.

Sdandard

Meet IEC 62752 mode II charging-related residual current test requirements.

Meet IEC 62955 mode three charging RDC-PD related residual current test requirements.

Meet the basic requirements of GB/T 22794 based on the adaptation of DC 6mA test requirements.

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
