GPIO4 and GPIO1 output are 3.3V. GPIO2 is 0V. But after reading the GPIO status…
Part Number: UCD9090A Tool/software: Hello team,
Can this device be configured to go back to certain point of the sequence step, when certain GPI inputs are present?
My customer wants to configure some complex sequencing, not just going forward the sequence…
Part Number: UCD9090A I am cascading 2 parts of power sequencer IC ( UCD9090A).
How i have to program cascaded ICs at same time?
How i have to monitor signals both ICs at same time?
Could you please share related document for power sequence programming…
Part Number: UCD9090A Tool/software: 1. A rail is under voltage and Fault Pin output low.
2.UCD9090A restart this rail, and voltage return to normal
3. Fault Pin keeps low unless reset UCD9090A
Q:FAULT PIN can not turn back?
Is VOUT_UV_FAULT a latch fault…
Part Number: UCD9090A Hi team,
Customer use the GUI (v7.10.1) by Offline Mode and refer the Guide " Fusion Digital Power Designer GUI 7.0 for the UCD90xxx Sequencer ".

Part Number: UCD9090A Other Parts Discussed in Thread: ASH We have designed in 2 UCD9090A devices (connected together) however I am not convinced the current release of GUI (7.9.1) is fully compatible. I tried installing it as admin and this did not appear…
Part Number: UCD9090A Hi team,
In datasheet 10.1 Layout guidelines,
4.99Ω resistor is recommended, but is not a common resistor value.
What is a reasonable resistance value for design (if possible, please let me know resistor product part number…
Part Number: UCD9090A Other Parts Discussed in Thread: UCD90SEQ48EVM-560 , UCD9090 We are currently designing the peripheral circuit for UCD9090A. The documentation recommends a 5Ω resistor and 4.7uF capacitor for the connection from V33D to V33A.…
Part Number: UCD9090A Hi team,
Is it possible to control multiple GPOs in one rail?
In datasheet, it is said that GPO are controllable up to 10 .
Does it mean one rail can control only one GPO?
Best regards,
Goto
