2.3.1 TUSS4470 Power Configuration

The TUSS4470 registers are easily configured in the 'Device Monitor' or 'Memory Map' tab of the TUSS Generation III EVM GUI. Some of the key register settings for device configuration are listed and discussed below.

The TUSS4470 EVM can be configured for a 5 V - 36 V VDRV voltage based on Table 2-1. The device configuration enumerated in each column will enable the respective voltage range for VDRV. Where register names are not explicitly listed, the value corresponds to the value seen in the TUSS Generation III EVM GUI.
