SLVSER3A November 2018 – April 2020 TPS65982BB
PRODUCTION DATA.
To enable the setting of multiple I2C addresses using a single TPS65982BB pin, a resistance is placed externally on the I2C_ADDR pin. The internal ADC then decodes the address from this resistance value. Figure 20 shows the decoding.
Table 3 lists the external resistance required to set bits [3:1] of the I2C unique address.
