Texas Instruments UCD9080
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.| Part No. | UCD9080 |
