TCAN1044V-Q1: About Supply Voltage Range

Yuya Shoji

Part Number: TCAN1044V-Q1

Hi team,

I have a question.

If the V_cc range between 4.482 and 4.5V, does this device unproperly transmit any signal to CAN bus line?

HI Shoji,

While the device may work with a VCC voltage <4.5V (4.482V), TI can no longer guarantee the electrical specifications listed in the datasheet.

For example, if you operate the device with VCC = 4.4V, Vo(DOM) for CANH and CANL minimum specs can no longer be guaranteed:

CANH(min) = 2.75V (no longer guaranteed)

CANL(min) = 0.5V (no longer guaranteed)

Tyler
