ENGINEERING SUPPORT HARDWARE LT1910

Product Number: LT1910

Hello ,

 LT1910 

  1. I don't quite understand, for this there is the diode that will bypass the capacitor during discharge?
  2. I need charging controlled by a capacitor/resistor around these values and that is normal .
  3. But when I perform a short on the EFUSE (Q8 mosfet) port it does not function and drops the internal voltage 8.2v to 0V
  4. Do I need a specific diode in the data sheets, they use 1N4148 and this is what I use, maybe I need a Schottky or FAST RECOVERY diode?
  5. Even if I put a 10NF capacitor in C235, and a 4.75K on R155 and on R157 value 10 ohm, It still does not work after short the EFUSE( see sch diagram)after I removed the capacitor C235 the voltage internal voltage dropped  8.2v to 0V. 
  6. I don't see this phenomenon in the simulation as I check on the card ?

Note : Only use "control network "
