ZHCSM91F May 2009 – January 2023 TCA6416A
PRODUCTION DATA
When power (from 0 V) is applied to VCCP, an internal power-on reset holds the TCA6416A in a reset condition until VCCP has reached VPOR. At that time, the reset condition is released, and the TCA6416A registers and I2C/SMBus state machine initializes to their default states. After that, VCCP must be lowered to below VPORF and back up to the operating voltage for a power-reset cycle.
