I need some help for VCR motor

[Jedi1]

Hi guys


I am new here,

I've been tried search on the website for chip LB11882N 48 SOP but can't find it

Don't know clue with pins

1. CFG
2. CAP VCC
3. 5.3VA
4. REV 'H'
5. I-Limit
6. M.GND
7. S.GND
8. D/LD VCC
9. CAP CTL
10. LD IN
11. DPG/FG
12. D.CTL

I would like to make a back/forward and button start VCR motor.

Hopefully someone can help me that, there a photo attachment here

Regards

Matty

Many datasheet websites offer links to a device because they know it exists but have you in loops trying to find a datasheet for it. I found this which is a similar named part with similar functions by the same manufacturer which maybe a start.

Forget what the Ic does, just find out what model VCR the capstan motor came outof. Then get the circuit of the VCR & find the pins that select FWD/REV on the conector. The VCR has to rev & fwd this motor.

Here is an example of a VCR capstan motor & how ive wired it to run in FWD/REV. You need to find what the pins do on your particular motor do. On this one Capstan control is for the speed of the motor, it starts the motor & the speed is varied by varying the voltage to this pin 4. Pin 5 is held hi (5v) to reverse the motor. Pin 7 is the main motor voltage. Pin 6 is the ICs working voltage. Pin 1 & 2 are the GND.

Hi Debe

Right, I dont have VCR model cos my friend gave me that VCR motor and PCB photo.

Do you think possible:

1. CFG = ignore it ??
2. CAP VCC = +5v supply power
3. 5.3VA = ignore it ??
4. REV 'H' = + 5v supply power ?
5. I-Limit ??
6. M.GND = To gound
7. S.GND = To gound
8. D/LD VCC +5v supply power ?
9. CAP CTL ??
10. LD IN ??
11. DPG/FG ??
12. D.CTL ??

I think its VCR model is LG and there is **broken link removed**
