Power Supply Sequencer And Monitor

The UCD9080 Power Supply Sequencer controls the enable sequence of up to 8 independent voltage rails and provides four general purpose digital outputs. The device operates from a 3.3-V supply, provides 3.2-mV resolution of voltage rails, and requires no external memory or Clock The UCD9080 monitors the voltage rails independently at more than a 20 kHz rate and has a high degree of rail sequence and rail error response configurability. The sequencing of rails CAN be based on timed events, or timed events in conjunction with other rails achieving regulation or a voltage threshold. In addition, each rail is monitored for undervoltage and overvoltage glitches and thresholds. Each rail the UCD9080 monitors CAN be configured to shutdown a user-defined set of other rails, and alarm conditions are monitored on a per-rail basis.
