UCD9090ARGZR VQFN-48 monitoring and reset chip price concessions
characteristic
10 voltage rails can be monitored and sequenced
All voltage rails are sampled every 400 µ s
12 bit ADC with 2.5V, 0.5% internal VREF
Sorting is based on time, voltage track and pin correlation
Each monitor has 4 programmable undervoltage and overvoltage thresholds
Each monitor can provide non-volatile error and peak logging (up to 26 fault detailed entries)
Closed loop margin adjustment for 10 voltage rails
The margin output adjusts the rail voltage to match the user-defined margin threshold
Programmable watchdog timer and system reset
Flexible digital I/O configuration
Respond to and monitor GPI triggered faults
Multiple power sequence generators can be easily cascaded and coordinated to provide fault response
Pin selection voltage rail status
Multiple devices can be cascaded
Multiphase PWM clock generator
The clock frequency is 15.259 kHz to 125 MHz
Capable of configuring independent clock output for synchronous switching mode power supply
JTAG and I2C/SMBus/PMBUS ™ Interface
explain
The UCD9090A is a 10 rail PMBus/I2C addressable power sequencer and monitor. The device integrates a 12 bit ADC for monitoring up to 10 power supply voltage inputs. There are 23 GPIO pins, which can be used for power enable, power on reset signal, external interrupt, cascade or other system functions. 10 of the GPIO pins provide PWM function. With these pins, UCD9090A supports margin adjustment and general PWM function.
Use the pin selection voltage rail status function to achieve specific power status. This function allows up to 3 GPIs to be used to enable and disable any voltage rail. This is useful for executing the system's low power consumption mode and for advanced configuration and power interface (ACPI) specifications for hardware devices.
TI Fusion Digital Power ™ Designer software is used for device configuration. This PC based graphical user interface (GUI) provides an intuitive interface for configuring, storing, and monitoring all system operating parameters.
