I will first start with the bottom side of the board which is mostly dedicated to power supplies generation and distribution.
On the following picture I've outlined various sections :
First we have the power supplies dispatchment which is mainly creating several supplies plans from the initial supply, starting with a ferrite bead which can serve as a fuse, some filtering with a inductor and a big output capacitor.
Secondly, there are secondaries voltages generated with regulators which are located in regulator sections 1 and 2.
And finally, a BA5888FP motor controller chip.
I will provide, as I finished them, analysis and schematics for these 3 sections.
A) Power supplies dispatchment
Here is a close up of the power supplies plans and components :
Here is a close up of the regulator components :
Next is a design taken from the TPS64201 Step down controller's datasheet, which is implemented by SONY on the board :
C) BA5888FP section
Here is a close up of the Motor driver IC :
This is based on the following datasheet diagram of an equivalent component :
Ok, schematic tool in place !
Schematics available as soon as I edit them !
Coming soon .....
Bonjour stefde69,
ReplyDeleteJe me tourne vers vous afin de savoir si vous pouvez me donner la demarche a suivre afin que je puisse reprogrammer mes volets roulants de chez becker sans ce fameux cable de programmation.
Vous avez ecrit,je cite:Mais après coup de fil chez Becker, on peut reproduire le fonctionnement de ce fameux câble de programmation en court circuitant les câbles d'une certaine façon, et cela fonctionne !!
Cordialement.
