TCAN1043HG-Q1: Question about TCAN1043HGDRQ1

Part Number: TCAN1043HG-Q1

Hello:

The attachment is the schematic of the in-vehicle wireless charger. The customer uses CAN with TI TCAN1043HGDRQ1.

There is one request and two assessments, please help support.

Power supply: 32V~58V.

Request: 1. Please help check the schematic.

Assessment:

1. The terminal has short-circuit tests. Test conditions: CAN_H shorted to power (32~58V) or CAN_L shorted to ground. Required network behaviour: communication should still work, but the signal-to-noise ratio decreases. Please assess whether this can be met.

2. In this circuit design, because there is a common-mode inductor, if CAN H/L is shorted to the power supply, is there a risk of excessive voltage causing IC breakdown.
