Hello,
For the DESAT protection in below schematic -
The Vdd = 20V & ICHG = 500uA current source.
As zener diode require some reverse current more than 1 mA, If zener value = 3.9V, will this zener is regulated with such low current value.
Also if Rlim resistor is added it will further reduce the current below 500uA.
Can anybody suggest will this DESAT protection work effectively.
