TPS1641: failed to reset in Surge test

Part Number: TPS1641


We use the TPS16410DRCR Auto-retry eFuse IC for protection. However, during our surge test with a +/-1KV signal every 1-minute interval, following the IEC 61000-4-5 standard(The 1.2/50 μs waveform represents the rise time (1.2 microseconds) and the time to half-value (50 microseconds) of the surge voltage. ), the TPS16410DRCR resets for 2 to 3 cycles, which is acceptable. However, after the 4th cycle, it enters a shutdown state and cannot be powered up until the 24-volt supply is restored. Please find the details of the schematic in the attachment and let me know.
