TIDEP0031, Power Sequencing Reference Design for K2E Using UCD9090 Power Supply Sequencer and Monitor

TIDEP0031, Power Sequencing Reference Design for K2E Using UCD9090. The K2E devices require power supplies to be sequenced in a proper order. This design demonstrates power sequencing for the 66AK2Ex and AM5K2Ex families of KeyStone II ARM+DSP and ARM-only multicore processors by use of the UCD9090. The UCD9090 is a 10-rail PMBus/I2C addressable power-supply sequencer and monitor. The UCD9090 provides both sequence and timing of the power supply enables. This design shows a power sequencing implementation specific to the K2E EVM platform
