Hello!
I have a circuit that is running on a serial signal from its onboard microcontroller, where the input signal are Clock/Strobe/Data. This signal input into a DC brushless motor driver that output 42Vdc@2A. It has an optical encoder feedback to the microcontroller to control the angle (360deg) of the motor shaft.
Here's my mystery!
Is it possible to BOOST the output of the motor driver to somewhere around 42V@8A, by changing the motor driver to a higher rating motor driver? If yes, what should I look at in order to "match" the original input specs (Clock/Strobe/Data)??
(FYI, the original optical encoder feedback will be remained by mounting it to the NEW more powerful motor shaft, same diameter of course!)
The original DC motor driver is Allegro A6628 (similar to A3996). My target replacement driver IC is Allegro A3985, because this has a capability of driving external MOSFET (range of 12-50V and 1-10A). The onboard microcontroller is a customised IC which we can access the inside of the driving signal or anything, thus, my hope is on the DC motor driver instead.
Please help !!!
