Dear team,
I have a question about TCAN4551-Q1 that need your support.
I found that on Ti.com, it says that TCAN4551-Q1 is without LDO and the TCAN4550-Q1 has LDO.
However, in the datasheets of TCAN4551-Q1 and TCAN4550-Q1, both show that have LDO inside.
The screenshot is shown as below:
Could you please help me to confirm whether TCAN4551-Q1 has LDO and what is the difference between TCAN4550-Q1 and TCAN4551-Q1?
Really appreciate your help and support!
Best regards,
Xenon Li
Both devices have an internal LDO. The difference is that the TCAN4550 can also supply power to other devices.
Xenon,
Clemens is correct, both have the LDO internally to supply the CAN bus bias, but the TCAN4550-Q1 also supports external use of this LDO to supply other devices.
Regards,
Eric Hackett
