TPS53667: IMON and READ_IOUT

Yuto Sakai
Mastermind 6100 points
Part Number: TPS53667

Hi,

TPS53667 has "READ_IOUT" register and "IMON" pin.
When TPS53667 is used with CSD95490, current information is communicated from CSD95490.

Where is the measurement point of READ_IOUT?
Also, I do not understand the measurement point for IMON.
It seems that the output current is monitored by the analog current output from the IMON pin and the VMON obtained by RIMON,
but where is the current output from the IMON pin determined by the information from?

Best regards,
Yuto Sakai

    The description of READ_IOUT can be found In page 21-22 in datasheet. Basically TPS53667 will take all CSPx signals reported from power stages, and then sum together internally, and use RIMON on IMON pin to adjust the gain if there is any gain error. READ_IOUT will be the converted results in linear format from VIMON via an ADC. Hope it is clear.
