That's correct.
Basically it's dedicated device for Drive Encryption/Bitlocker. It provides the benefit of Integrity Checking when the computer is offline to detect if there has been any tampering.
For example,
Moving the BitLocker-protected drive into a new computer.
-Installing a new motherboard with a new TPM.
-Turning off, disabling, or clearing the TPM.
-Changing any boot configuration settings.
-Changing the BIOS, master boot record, boot sector, boot manager, option ROM, or other early boot components or boot configuration data.
