Rf Transceiver module to drive a vibrating motor.
okay, to the subject direct, i am working on RF Transceiver module, using remote control with four buttons, and required to drive a vibrating motor with every button click, momentary " as long as button is pressed the motor is vibrating" , the module is paired of pt2262 transmitter, and pt2272 receiver, which gives four separate outputs, what i need is to use these outputs to drive the motor, so a driver issue, which i need your help with.
I used C1815, and C549, tried Mosfet IRF540, K1611, and tested on a led, the Led flashed on, when pressed the remote button, but when put the motor instead of led, never worked.
The motor consumes 80ma at 4.5dcv, and attached the receiver circuit, and how i connected the driver.
will appreciate your reply, as i googled a lot, and made many trials, but no result as i wanted.
Regards.

Sorry couldn't upload the driver circuit i used, so you just suggest one according the attached schematic, Thanks.
I think is a mistake in the circuit diagram. How is biased the oscillator transistor (Q2) in this moment, the collector current it is very low (~15uA) which makes impossible the circuit to oscillate.
The circuit works fine vfone, gives its outputs when pressing remote buttons, so just tell me how to take these outputs of pt2272 to drive a vibrating motor.
Thanks for your care to reply.
hi ,
try bipolar transistors in darlington connection .
Sorry, I didn.t understand where do you connected the mosfet in the circuit. Could you post also the schematic diagram of the mosfet based led driver (as far as I understood is working) ?
However ouputs of the IC are on Dx pins (10, 11, 12 and 13), but if the led is switched on correctly I think the problem is about mosfet biasing.
Hello all again,
albbg, the mosfet circuit i can't provide for now, but what i arrived to while working on that circuit, that it's not the driver issue to know how to connect, cause i used same connections using transistor with manual switch and it drived the motor when pressed the switch, so now it's the Dx pins, which makes the led flashes instead of turning on when connecting direct, so it's how to convert the Dx output to stable voltage while loading?
here is the link of where i bought the kit " Rf transmitter and receiver":

Thanks to you all for your care to help.
Maybe your physical circuit works fine, but what I said is, the schematic you posted is wrong.
ok vfone, Let's say the schematic have something wrong, How can i correct that with it, so it can oscillate the transistor to drive the motor?.
