STAND BY SUPPLY +3VALW AND +5VALW IN CQ40

Voltage Generate +3valw and +5valw in cq40 reserve supply

After +3vl drive the EC there is ACIN motion from lm393 is go to EC on stick no.127. It let EC know the air conditioner connector is connected to and EC stop the ACOFF motion out from it. ( note: when connector hauled out ACOFF flag makes high and tell the framework connector not connected to or AC framework is OFF). 

The Technical Junction

  

At the point when ACOFF Signal Stops Schmitt-trigger inverter PU302 stick no.2 input is low and it transform the Signal to yield on stick no.4 and make it high 3.3v (it Work here like not Gate) .

The Technical Junction

in the wake of getting high contribution on entryway of PQ308 mosfet it ground the empty Voltage which is leaving VL through PR313 obstruction. by this both door voltages of PQ305 and PQ306 go to 0 volt or handicap so the ENTRIP1 and ENTRIP2 make high and it empower the pwm flag yield to DRBH1, DRVH2 ,DRBL1 and DRVL2 by which +3valw and +5valw produces on PL303 and PL302.

The Technical Junction

VBST1 and VBST2 give additional charge and strength to yield supplies .
