Bq40370 < 2027 >

It is important to distinguish the bq40370 from other TI gauges to ensure the correct part is selected.

One final note for reverse engineers: The bq40370 supports . Many OEMs enable the "Authenticate on Seal" bit. This means that even if you perfectly emulate the SMBus protocol, the host laptop/tool will send a 160-bit challenge to the bq40370. If the chip does not return the correct hash (computed by a secret key burned into the IC's ROM), the host refuses to turn on the system. You cannot extract this key via side-channel attacks easily. bq40370

Battery Management Studio (bqStudio) by Texas Instruments is the official tool for evaluating and configuring the chip's data memory. Issues and Solutions It is important to distinguish the bq40370 from
