Part Number: LM66100EVM Other Parts Discussed in Thread: LM66100 Hello Experts, My customer is testing EVM and confirmed unexpected reverse current(around 1mA). I think that reverse current is I suppose that reverse current is Iout,off(~few uA). Would you…
Part Number: LM66100EVM Hello Experts, My customer is evaluating LM66100EVM. He mentioned that the reverse current is too high as unexpected. I suppose that reverse current is Iout,off. Please look at below JP settings and please give your comments if…
Part Number: LM66100EVM Other Parts Discussed in Thread: LM66100 , TPS2121 Hello Experts,
I am testing the LM66100EVM board with an OR-ing application where I use two batteries for Vin1 and Vin2.
I have noticed that when I reverse one of the batteries…
Part Number: LM66100
Hello, I have a project that has two CR2450 in parallel. These batteries can be inserted backwards so I need to protect for that. I am looking at using two LM66100, one for each battery.
Here is the circuit I am looking at using. VIN1…
Hi Elizabeth
I have used the LM66100EVM and checked if the wrong polarity is working or not!!!

When I use the wrong polarity at input. it is protected and…
Thanks Kalin,
If I understand you correctly - the reason PMOS isn't needed to protect (2x LM66100) OR'ed section, but because V_VBAT is extended out to U20 and TPS22919 doesn't support RPP, is that correct? In other words - if my application…
Hi Jose,
We are currently aware of an issue on the LM66100 PSPICE model with regards to OR-ing with a PFET.
We are working on fixing these issues internally. I have personally seen the issue you are referencing and I can confirm that this is not the…
Part Number: LM66100 Other Parts Discussed in Thread: , TPS2116 , TPS2121 , TPS2113A , TPS2115A Hello team,
we have a hand-held computerized spirometer that works with two AAA batteries or with USB. We are using two schottky diodes in typical ORing configuration…
Using the LM66100EVM, I can configure the board to the diode ORing configuration that I want to use ( see Figure 9 of datasheet).
If I connect Vin1 backwards (-3V), I get 282mA current flowing from Vin1 (with no load on Vout).
If I remove JP7 (1K resi…
