TPS61391: questions about TPS61391 spec on page #5

Part Number: TPS61391
Other Parts Discussed in Thread: TPS61390, INA191

Hello,

 

My customer has the following questions about TPS61391 spec on page #5 of the datasheet.

 

  • They would like to use TPS61390 at IAPD = up to 4mA. In this case, how much would KMON1 and KMON2 be respectively (min/typ/max)?

  • They do not understand what the VON(MON1/MON2 Threshold) exactly is. Could you elaborate?

  • Is VAPD_DRP the drop voltage between MONIN pin and APD pin?

  • There is an item called Current mirror bias current, but they don't know where the bias current flows, so can you tell them where it hits in the block diagram on page #9?

  • How many volts can the output voltage of MON1 / MON2 be output based on AVCC? (Can it output up to 3.3V like the current sensor INA191?)

 

Best regards,
