SLVSLJ5 March 2026 TCA9846
ADVANCE INFORMATION
When power is applied to the VCC pin, an internal power-on reset holds the TCA9846 in a reset condition until VCC has reached VPORR. At this point, the reset condition is released, and the TCA9846 registers and I2C state machine are initialized to the default states, all zeroes, causing all the channels to be deselected. Thereafter, VCC must be lowered below VPORF to reset the device.
