UCD9090 - 10-Channel Power-Supply Sequencer/Monitor

The UCD9090 is a 10-rail PMBus/I2C addressable power-supply sequencer and monitor. The device integrates a 12-bit ADC for monitoring up to 10 power-supply voltage inputs. Twenty-three GPIO pins can be used for power supply enables, power-on reset signals, external interrupts, cascading, or other sys.

UCD9090 Features

* 1 Monitor and sequence 10 voltage rails

* All rails sampled every 400 μs

* 12-bit ADC with 2.5-V, 0.5% internal VREF

* Sequence based on time, rail and pin dependencies

* Four programmable undervoltage and overvoltage thresholds per monitor

* Nonvolat
