Part Number: MAX3232E
My customer wants to use 3.8V to supply for MAX3232E. According to datasheet, MAX3232E can operates with 3-V to 5.5-V VCC supply so I think 3.8V power supply should be OK. But I noticed that in below recommended operating condition, why there is a voltage range limitation for VCC=3.3V and VCC=5V? Can you help confirm if any voltage value from 3V~5.5V can be used to power MAX3232E? Thanks.
Yes, MAX3232E can work with any supply voltage between 3V and 5.5V. However please make the external capacitor configured as recommended on the datasheet.
The reason is to make sure the peak voltage due to the charge pump operation is within the designed limit. For the detail, please check out this blog.
We are glad that we were able to resolve this issue, and will now proceed to close this thread.
