Part Number: ISOW7842 Other Parts Discussed in Thread: LP2985A , , ISOW7742 Hello!
I'm supplying the LDO LP2985A with the output of a ISOW7842 (3.3V primary driven). The output can be as low as 3.13V (for currents up to 30mA) and the dropout voltage…
Part Number: ISOW7842 Other Parts Discussed in Thread: ISOW7742 Hey team,
Just curious, what do we specify as to what will happen if a voltage is applied on the input while the device is Vcc=0? I couldn't find anything in the datasheet except the following…
Part Number: ISOW7842 Hi,
In our design using ISOW7842, we are facing exactly the same behaviour of the "VISO latch-up" as described in this thread: https://e2e.ti.com/support/isolation-group/isolation/f/isolation-forum/769224/isow7842-latch…

I am using ISOW7842 in two locations to create a Viso.
In both location the downside Vcc measures 3.312V.
In one location Viso measures 3.717V…
Part Number: ISOW7842 Hello guys,
One of my customers is considering using ISOW7842DWE for their new products.
At this moment, they have the following questions about ISOW7842DWE. Could you please give me your reply?
Q1. Figure 7-31 on page 32 of the device…
Part Number: ISOW7842 Hello,
In the datasheet, it says that the default output state for the non-F version is HIGH and the default output state for the F version is LOW. I am confused by one of the diagrams shown in the datasheet:
For the non-F version…
Part Number: ISOW7842 Other Parts Discussed in Thread: ISOW7742 Hello guys,
One of my customers is evaluating ISOW7842 for their new products. They monitored VCC terminal input current waveform with the following conditions.
1. 10uF and 0.1uF ceramic capacitors…
Part Number: ISOW7842 Hi Team,
Our customer would like to request the following specifications as they are working on a very fast gate drive circuit and need to know how the ISOW7842F varies as a function of other inputs.
Data For Channel-Channel skew(Supply…
Part Number: ISOW7842 Other Parts Discussed in Thread: ISOW7742 Hello
I am trying to figure out in which situations which of my output signals will be in an undetermined state as described in the datasheet in chapter 9.4. There it is state underneath…
Part Number: ISOW7842 Hello!
I have a design with the ISOW7842DWE isolated 3v3 chip. We have had an issue with the voltage of the ISO side dropping to 0.3 or around 2 V. The resistance between iso_3v3 and iso_GND are on some chips around 2-3 ohms and…
