Hello, all
Now we have some inquiries regarding undervoltage threshold on SN65HVDA1050A-Q1 from our customer.
Please refer to the items below, and feedback us with your comment.
When referring RECOMMENDED OPERATING CONDITIONS on datasheet page 6, Vcc operating range is defined as 4.75 to 5.25V.
Meanwhile, when referring ELECTRICAL CHARACTERISTICS on datasheet page 7, UVCC threshold is defined as 2.8 to 4V.
Please let us clarify how this device could operate if 4V to 4.75V is supplied into VCC pin.
Also, when referring "Undervoltage Lockout / Unpowered Device" on datasheet page 4, TXD pin is pulled up to VCC. However, we could not find out how RXD pin would be treated.
Please let us clarify how RXD pin would be treated on this case.
We thank you in advance for your information.
Best regards,
