Part Number: UCD90240 Hi ,
Our customer want to use command to control margin low or margin high.
According to the pmbus document , that should be operation command.
However the PMBUS command document only show the data byte was avaiable for 0x00 , 0x40…
Part Number: UCD90240 Hello,
I have a customer that would like to monitor different rails than they are enabling.
They have 24 rails to monitor, and will enable 18 of them. So for MON[0:17] and EN[0:17] they each are directly related and monitoring/enabling…
Part Number: UCD90240 Hi,
Page 42 of the device datasheet states "One 1-μF X7R ceramic capacitor in parallel with one 0.01-μF X7R ceramic capacitor for VREFA+ decoupling".
On the UCD90240 EVM, we place .01uF, .1uF, and 10uF capacitors…
Part Number: UCD90240 Hi,
Do we provide material as below for customers?
1. Sample code for UCD90240
2. UCD90240 program tool, and how to program it.
Thanks!

Part Number: UCD90240 Hi ,
I am confusing on the logic when using Pin Selected Rail States Configuration.
If PMBUS Command was OFF but Pin Selected Rail States was assert , what will enable pin become ?
If PMBUS command was ON but Pin Selected Rail States…
Part Number: UCD90240 When using this chip in Fusion Digital Power Designer I am having trouble setting the GPIO pins (GPIO1-24) to the open drain configuration. Most of the devices that I am connected to are 1.8V IO so open drain in conjunction with…
Part Number: UCD90240 Hello Team,
Posting on behalf of customer.
Due to board space constraints, would prefer to eliminate input resistors on MONx inputs of UCD90240.
how important is this recommendation? Is it a matter of slightly decreasing voltage…
Part Number: UCD90240 Hi team,
I have a customer looking for the BSDL file for the UCD90240. I am unable to find one, and after searching similar requests it sounds like these support ATE scan, and have JTAG programmability, but not boundary scan (BSDL…
Part Number: UCD90240 The datasheet says that the use of these 2 pins are optional, but when not using them is it alright to leave them floating when using the internal voltage reference? None of the reference circuits show a case in which only the internal…
Other Parts Discussed in Thread: UCD90240 Need to monitor 48reals with 2X UCD90240.
Do you have design recommendation? should we use 2 or mode devices, is the project common or do need to design them separately?
