(1) All typical values are at nominal supply voltage (1.8-V, 2.5-V, or 3.3-V V_CC) and T_A = 25°C.

(2) When power (from 0 V) is applied to V_CCP, an internal power-on reset holds the TCA6408A-Q1 in a reset condition until V_CCP has reached V_PORR. At that time, the reset condition is released, and the TCA6408A-Q1 registers and I²C/SMBus state machine initialize to their default states. After that, V_CCP must be lowered to below V_PORF and back up to the operating voltage for a power-reset cycle.
