BQ25703A Would not accept charge commands!

[ali_asadzadeh]

Hi,
I have designed a sample board to play with the BQ25703A, the problem is that I can read and write every register, but when I try to write these commands,
ChargeCurrent,MinSystemVoltage,

 BQ25703A  seems to reset and do not accept the commands.

Also when the battery pack is disconnected the ChargeOption0 command would take effect, but when I connect the battery pack it would not get the values.

Here is some parts of my code

Code: [Select]

	int status;
	//ChargeOption3 Reset All Registers to default
	BQ25703WriteReg(0x34,0x6000);


	//ChargeOption0 			
	BQ25703WriteReg(0,0x060E);
	status=BQ25703ReadReg(0x0);
	//ChargeOption1
	BQ25703WriteReg(0x30,0x9211);
	status=BQ25703ReadReg(0x30);
	//ChargeOption2
	BQ25703WriteReg(0x32,0x02BF);
	status=BQ25703ReadReg(0x32);
	//ChargeOption3
	BQ25703WriteReg(0x34,0x0000);
	status=BQ25703ReadReg(0x34);
	//ProchotOption0
	BQ25703WriteReg(0x36,0x4A54);
	status=BQ25703ReadReg(0x36);
	//ProchotOption1
	BQ25703WriteReg(0x38,0x1000);
	status=BQ25703ReadReg(0x38);
	//ADCOption
	BQ25703WriteReg(0x3A,0xE0FF);
	status=BQ25703ReadReg(0x3A);
	//MaxChargeVoltage
	BQ25703WriteReg(0x04,0x41A0);
	status=BQ25703ReadReg(0x04);
	//ChargeCurrent @1A
	BQ25703WriteReg(0x02,0x0400);
	status=BQ25703ReadReg(0x02);
	//MinSystemVoltage @14.336V
	BQ25703WriteReg(0x0C,0x3800);
	status=BQ25703ReadReg(0x0C);
	//IIN_HOST @1A
	BQ25703WriteReg(0x0E,0x1400);
	status=BQ25703ReadReg(0x0E);
	//InputVoltage @8.192
	BQ25703WriteReg(0x0A,0x2000);
	status=BQ25703ReadReg(0x0A);
	//OTGVoltage @12.67V
	BQ25703WriteReg(0x06,0x2000);
	status=BQ25703ReadReg(0x06);
	//OTGCurrent @1.6A
	BQ25703WriteReg(0x08,0x2000);
	status=BQ25703ReadReg(0x08);

read and write functons

Code: [Select]

void BQ25703WriteReg(int add,int data)
{
	static HAL_StatusTypeDef mySTs;
	unsigned char write_message[3];
	write_message[0]=add;
	write_message[1]=data;
	write_message[2]=data>>8;
	mySTs=HAL_I2C_Master_Transmit(&hi2c1,BQ25703_ADD,write_message,3,1000);


}

int BQ25703ReadReg(int add)
{
	int res=0;
	
	unsigned char write_message[1];
	
	write_message[0]=add;
	
	unsigned char read_data[2]={0};
	HAL_I2C_Master_Transmit(&hi2c1,BQ25703_ADD,write_message,1,1000);
	
	//start to read RTC Data
	HAL_I2C_Master_Receive(&hi2c1,BQ25703_ADD,read_data,2,1000);

	res=(read_data[1]<<8) | read_data[0];
	return res;
}

Do you have any Idea what's wrong?
