BQ51222: LPRB Excel tool (again)

Hello

The BQ51222 / 221 are dual mode device supporting both WPC (Qi) and PMA standard, do not recommend this device.  A better device to look at is the BQ51020 / 021 they are WPC only devices and P2P with 222.

The BQ51222 / 221 are designed to and earlier PMA standard and are not current.  We are not supporting PMA option on this device, recommend the WPC only units.

LPRB is only used for the PMA.

EVM default values can be used for LPRB:

LPRB1 pin F5 = 102k

LPRB2 pin G6 Open

Thank you for your speedy reply, but i'm inclined to refuse your recommendations. The 020/021 ICs only support WPC 1.1, whereas the 222/221 support WPC 1.2 (which my employer seems to like). I understand that the PMA spec is defined in a rather unfortunate way, and i have no intention of complying with it either, but i guess i'll just leave the TERM/LPRBEN pin floating, removing the need for LPRB resistors alltogether. I was hoping however to make use of the NTC calculation tool in the afformentioned Excel file. Could a simple 10k resistor disable the NTC functionality (like with the BQ51013 and BQ51003 and such)?

WPC 1.2.4 and BQ51020 / 021 --- The devices will meet WPC 1.2.4 standard also.   For WPC Base Power Profile (5W) the RX ID can be 1.1 if unit meets all WPC 1.2 requirements and they do.  The transition from 1.1 and 1.2 for 5W receiver was very limited, few changes.  The RX ID packet is sent to transmitter that identifies WPC revision. 

NTC --- Yes if a 10k resistor is used in place of NTC it will disable the TS / NTC feature.  The device is still protected by a thermal shutdown feature on the die at 155C.
