Part Number: HALL-TRIGGER-EVM Other Parts Discussed in Thread: DRV5032 Tool/software: Hi, Could you please suggest an alternate with Lower cost with same Pin & similar Package for below MPN: AH180N-WG-7 (Hall Effect Switch). Maximum output voltage should…
Part Number: AMC1300 Other Parts Discussed in Thread: AMC-AMP-50A-EVM
Tool/software:
Hi team,
When AMC1300 is used in solar inverter phase current sensing, the SiC MOSFET is TO247-4 package, pls check below questions:
1. Should INN pin be connected…
Part Number: BQ25798 Tool/software: Hello!
My team and I are currently working on integrating the BQ2598 Charger Chip into our hardware design. We are using the BQ25798EVM board for reference to verify our readings and to identify any discrepancies…
Part Number: BQ24650 Tool/software: Hello,
I’ve been using the BQ24650EVM-639 user guide to help with the design of my board. The schematic shows that components without values (C9, C13, R4, R8, and R16) are not installed.
I’m curious about the purpose…
Hello Deepakji,
Deepakji said: Right now we are using the EVM, so the FETs on the EVM are as it is.
Let me look into this and get back to you.
Deepakji said: In this case the input current will be limited to less than 1A all the time right? So this…
Hello Christian,
We've finished a set of tests and have concrete results, and I can assure you that the BQ24650 doesn't start charging on a fully discharged battery (zero volt).
To make it clearer, I'll describe the totality of the tests carried out…
Part Number: TPS23861 Other Parts Discussed in Thread: TPS40210 , LM5575 Tool/software: We have used the TPS23861 PSE in a number of different product designs, selling a few thousand each year. We have had a number of failures where all 4 ports stop providing…
Hi Elvis,
BQ25672 is a buck only charger so VBUS >= VREG is required to complete a charge cycle. The PCB layout does not follow the recommended layout per the datasheet = EVM layout. Frankly, I can't figure out the layout because the pin out does not…
Hi,
I don't fully understand the design requirements. The BQ25756 is a high power charger. We can do low power levels, but that isn't really what the device is meant for. Are you looking for a switching charger with MPPT? If so, does the MPPT need to…
Part Number: BQ25570
Tool/software:
Howdy,
I am considering designing with this energy harvester and am a little confused about possible input sources. The recommended designs show high input impedance sources such at TEG's or solar cells or vibration…
