Hello Matthew,
The BQ76940 is not recommended for Lithium-Titanate cells. It is intended to be used with higher nominal voltage batteries.
This is explained briefly in this older e2e thread: https://e2e.ti.com/support/power-management-group/power-management/f/power-management-forum/876800/bq76940-can-bq76940-be-used-for-lithium-titanate-cells
The BQ76952 is now released and may work, but we are suffering from stock issues at the moment. So these may not be readily available.
Best Regards,
Luis Hernandez Salomon
