[ Upstream commit 2c95a756e0cfc19af6d0b32b0c6cf3bada334998 ]
The TPS23881 improves on the TPS23880 with current sense resistors reduced from 255 mOhm to 200 mOhm. This has a direct impact on the scaling of the current measurement. However, the latest TPS23881 data sheet from May 2023 still shows the scaling of the TPS23880 model.
