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…

Hello TI team,
Recently, I have been using the resistance-programmed BQ25756E as the output for the wireless power transmission (WPT) module. At the beginning, the initial power I input to the BQ25756E was lower than the normal working…
您好
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…

Part Number: BQ25890 As we know, for BQ25890,IINLIM or IDPM_LIM can be used by DPM. But what's the usage of ILIM pin controlled input current limit? That's to say if the input current limit of Charger is determined by ILIM pin, what will happen when the…
