This is the block diagram of the TPS92411P. What is the meaning of the symbols highlighted in red?

Hi Punsara,

Thanks for reaching out. Since TPS92411 is an old device, we need some time to check this question. If everything goes smoothly, I will get back to you within a week.

Thanks for your understanding.

Best Regards,
Steven

Hi Punsara,

Please refer to my answer below:

The symbols highlighted in red are current mirrors. The 2x and 1x means the ratios of the mirrors. The half circle means the input of the current mirror. (For example, for the upper current mirror you highlighted, the reference current is set by the resistor connected to RSNS pin. This reference current is divided by 2 and mirrored to both left side and right side.)

Best Regards,

Steven
