Can you provide a register dump?
Do you have a system load? Do you see this issues without a system load?
What is the battery voltage and charge current?
Do you have a current limit on the input supply?
Is this for the gate driver? You can check the supply current whether its supply current exceeds HV start-up current out of VDD, the typical value is 250uA. The gate driver VCC sink current is too large to limit the VDD rising up.
You can refer to the…
Hi Team,
I would like to add a little more information. The power supply settings are: voltage 23.5V, current limit 2.1A. The current is 2.1A when the host is charging. The test is as shown on the right, which meets the current limit requirements. The…
Hi,
The board could hit input current limit. Could you try below register settings with input current limit/protection disabled?

1. NTCs seem to be pre-charge path.
2. When the C pin of LM74801-Q1 is left floating, the reverse current blocking functionality is disabled. So, the device will allow reverse current flow through the MOSFETs. Now with the C pin floating, the device will…

To set the maximum input current using the ILIM_HIZ pin, a pull-down resistor to PGND is used. When using a 2-mΩ RAC_SNS resistor, the input current limit is controlled by: IAC_MAX = KILIM / RILIM_HIZ. The actual input current limit is the lower value…
