2.3 Power Sequencing and Supervising
The components on the NetFPGA-SUME require that the supply voltages be sequenced on and off in a particular
order. The NetFPGA-SUME utilizes two Linear Technology LTC2974s to ensure that these sequencing requirements
are met. Each LTC2974 supports "cascade sequence ON with time-based sequence off" and can monitor the input
voltage, four output voltages, four output currents, and four external temperatures using a 16-bit ADC.
