Other Parts Discussed in Thread: HVDA551-Q1
Hi team,
When my customer used HVD1050 for surge test, he found that when CANH and CANL add negative 2kV surge to ground, HVD1050 will be damaged, and the impedance of CANH and CANL to ground will decrease, but this problem will not occur when replaced with HVDA551. Could you please help with the following:
1. The difference between HVD1050 and HVDA551 CANH and CANL internal circuits.
2. Analyze why HVD1050 will be damaged based on the following test waveform?
The following are the CANH to GND test waveforms before the two HVD1050s are damaged
