TPS53679: 电源管理论坛

Part Number: TPS53679

1、

1、上电顺序一定要按照上面的规定吗?,如果同时上12V,5V,3.3V会引起保护吗?

Do you have to power it on in the order above? Is there protection if 12V,5V, and 3.3V are powered on at the same time?

2、我现在就是同时上电,然后依次下下面的指令,VOUT端没有电压输出 。

I am now powering on at the same time, and then input the following commands in sequence, but the VUOT has no output voltage.

// data[0] = 0x00; data[1] = 0x00;
// HAL_I2C_Mem_Write(&hi2c1,0xC2,PMBC_PAGE,I2C_MEMADD_SIZE_8BIT,data,2,100);
// HAL_Delay(100);
//
// data[0] = 0x00; data[1] = 0x00; data[2] = 0xC9;
// HAL_I2C_Mem_Write(&hi2c1,0xC2,PMBC_VOUT_MAX,I2C_MEMADD_SIZE_8BIT,data,3,100);
// HAL_Delay(100);
//
// data[0] = 0x00; data[1] = 0x00; data[2] = 0x00;
// HAL_I2C_Mem_Write(&hi2c1,0xC2,PMBC_VOUT_MIN,I2C_MEMADD_SIZE_8BIT,data,3,100);
// HAL_Delay(100);
//
// data[0] = 0x00; data[1] = 0x00; data[2] = 0x79;
// HAL_I2C_Mem_Write(&hi2c1,0xC2,PMBC_VOUNT_COMMAND,I2C_MEMADD_SIZE_8BIT,data,3,100);
// HAL_Delay(100);
//
// data[0] = 0x1B; data[1] = 0x1B;
// HAL_I2C_Mem_Write(&hi2c1,0xC2,PMBC_ON_OFF_CONFIG,I2C_MEMADD_SIZE_8BIT,data,1,50);
// HAL_Delay(100);
//
// data[0] = 0x80; data[1] = 0x80;
// HAL_I2C_Mem_Write(&hi2c1,0xC2,PMBC_OPERATION,I2C_MEMADD_SIZE_8BIT,data,1,50);
// HAL_Delay(100);
