Part Number: HVDA551-Q1 Tool/software: Hi Expert,
Customer find there is HVDA551-Q1 failure in their vehicle. The phenomena is: CANH to GND is 3ohm. CANHL to GND is 4ohm. External components like TVS and cap are all good.
Now they use SMAJ18CA as…
Part Number: HVDA551-Q1 Tool/software: Hi Expert,
Customer find HVDA551-Q1 CANH and CANL waveform jitter and the low level voltage is about 0.7V, which is higher than 0.5V. Every board has this issue, so this could be related to schematic and layout…
Part Number: HVDA551-Q1 Hi team,
when customer test HVDA551, they found CANH and CANL is abnormal, have a small voltage anomalies.
Could you please help analyze why this phenomenon occurs based on the following information.
Point-to-point communication…
Part Number: HVDA551-Q1 Hi team,
I found that HVDA551 recommended Differential input voltage is -6~6V, because CANH and CANL of HVDA551 will exceed 6V when doing EMC test, could you pls help share the HVDA551 Max differential voltage between CANH and…
Part Number: HVDA551-Q1 Hi Support Team.
A customer is considering this product as a replacement for another company's product and has requested an EMC TEST Report.
Could you please obtain the EMC TEST Report for HVDA551QDRQ1?
Thanks,
Yutaro…
Part Number: HVDA551-Q1 Hi team,
My customer is using HVDA551QDRQ1. The other side of HVDA551 is a PLC and the terminal resistor is 120 ohm. HVDA551 VCC=5V and VIO=3.3V.
When HVDA551 is sending data out, we measured its differential output voltage…
Part Number: HVDA551-Q1 On the datasheet, there are two particular features listed:
- Data rate up to 1Mbps
- Supports Can Flexible Data-Rate (FD)
Does the latter imply that the transceiver can accept CAN-FD messages with payloads of up to 64 bytes…
Part Number: HVDA551-Q1 Hi Team,
Do we have maximum rise and fall time of HVDA551-Q1 differential output signal can share with the customer? The datasheet only mentioned the typical value of these specs.
Best Regards,
Nick Dai
Other Parts Discussed in Thread: HVDA551-Q1 Hi,
I got a question about the technique for improving EMC.
Customer got the info about it from our competitor as follows,
