UCD9081 - 8-Channel Power-Supply Sequencer/Monitor

Description

The UCD9081 power-supply sequencer controls the enable sequence of up to eight independent voltage rails and provides four general-purpose digital outputs (GPO).

The device operates from a 3.3-V supply, provides 3.2-mV resolution of voltage rails, and requires no external memory or clock.
