hi friend,
i will try to solve to your problem.
i think ur using arm processor. each pin configured as pullup,pulldown,open drain. otherwise any open drain pin is available, connect that pin to directly gate of maosfet and resistor(10k) connect source to gate. then i think ur problem will solve.
hello,
I am controlling GSM 4.4v power supply with AO3409 ( its vgs(theresold)=2.4v at 250uA). I am controlling gate of mosfet with 3V logic level signal. but my problem is , i am unable to controll the 4.4v power. it is always ON. please fix my probelm. how to select mosfet with...
hi to everyone.
I am unable to conver allegro board file (.brd) to orcad layoutplus(.max). i follewed some stepls , like open the dxf editor, mapping the all layers, converted to dxf format.
Aftert that i am importing dxf file into orcad layout plus, but i am getting only silk screen...
hi
i unable convert .dra (allegro board file) to orcad layout(.max).
i am able to convert .max to .dra, but i am not able to convert .dra to .max.
i am following some stepls, i am mapping all layers,classes,sub classes in allegro dxf editor, i converted into dxf format.
but on importing .dxf...
hai i am using mc34063 in my project as stepup dc-dc converter.
input range is 3.5 to 4.5dc. out put is 24v, 80mA.
as per datasheet, its input voltage recommended is 3v to 40v dc.
I calculating all values, input peak current not exceed 1.5AMP.
i am mentioning calculated values:
Rsc=0.22ohms...
thank u for valuable information. but i think 4.5vdc biasing voltage go to microcontroller pin. is it any problem. now i am going choose AO3409, which has VGs=2.4v, i think it will solve my problem

thank you for...
hai to everyone,
i have one problem, anybody can solve it.
i am using p channel Mosfet(NX2301p) as controling power.
i am given 4.5 dc volatge to source and i am controlling gate with 3v logic control signal, but at drain continusly 4.5dc passes to drain. it is not controlled. i will not use...
