SLVSLJ5 March 2026 TCA9846
ADVANCE INFORMATION
When power (from 0V) is applied to VDD, an internal power-on reset holds the TCA9846 in a reset condition until VDD has reached VPOR. At that point, the reset condition is released and the TCA9846 registers and I2C state machine initialize to the default states. After that, VCC must be lowered to below VPOR and then back up to the operating voltage for a power-reset cycle.
