Overview
The UCD90120 Power Supply Sequencer and System Health Monitor monitors and sequences up to 12 independent voltage rails. The device integrates a 12-bit ADC with a 2.5V internal reference for monitoring up to 13 power supply voltage, current, or temperature inputs. 26 GPIO pins can be used for power supply enables, power-on reset signals, external interrupts, cascading multiple UCD90120 devices, or other system functions. 12 of these pins can be used as PWM outputs for power supply margining or general-purpose PWM functions including clock generation for switch-mode power supplies. The TI Fusion Digital Power Designer is provided for device configuration. This PC-based Graphical User Interface (GUI) offers an intuitive interface for configuring, storing, and monitoring all system operating parameters. The UCD90120 has an I2C/PMBus/SMBus communication interface for pre-production and in-system configuring and monitoring and a JTAG Port for production programming.
