BQ25713: Default register value

S.Satoshi

Part Number: BQ25713

Hi,

Before I asked about default value of IIN_HOST Register as below.

e2e.ti.com/.../2972215

But now I found another differences between datasheet and EVM. So can you define the correct default value of following three register?

ChargeOption0 Register (I 2C address = 01/00h) [reset = E60Eh]

Title : 1110 0110 0000 1110 = E60E
Table : 1110 0011 0000 1110 = E30E
EVM : 1110 0111 0000 1110 = E70E

ProchotStatus Register (I 2C address = 23/22h) [reset = 0h]

Title : 0000 0000 0000 0000 = 0000
Table : 0010 1000 0000 0000 = 2800
EVM : 1010 1000 0000 0000 = A800

ProchotOption0 Register (I 2C address = 37/36h) [reset = 04A61h]

Title : 04A61 ???
Table : 0100 1010 0110 0101 = 4A65
EVM : 0100 1010 0110 0101 = 4A65

Satoshi-san,

Thank you for the information. We will conduct the lab EVM checking after the US holiday and get back to you about the discrepancy.

Hi Satoshi-san,

Today is a holiday in the US, but I will verify the POR values for the above when I return to the office tomorrow.

Steve

Hey Satoshi-san,

For ChargeOption0, the correct POR value is:
0xE70E. There are typos in the datasheet table and title.

For ProchotStatus, the POR value can be variable in the second byte.
Therefore, we cannot write a fixed POR value in the Title. Under all normal operating conditions, the charger should read 0xA800; however, if a Prochot fault is present at POR, the state of this register can be different. It will remain 0h in the title.

You are correct, however, that the table should have bit 7 of the first byte set as 0b1 and not 0b0.

For ProchotOption0, the correct POR value is:
0x4A65. There are typos in the datasheet title.

Thank you for your input. This changes will be included in the next revision of the datasheet.

Regards,
Joel H
