UCD9080 Datasheet 8-channel Power-supply Sequencer/monitor

Manufacturer: Texas Instruments

Overview: UCD9080 .ti....................................................................................................................................................

General Description

The UCD9080 power-supply sequencer controls the enable sequence of up to eight 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.
