I bought the PWM controller UC2638 in order to control 2 directions for my DC motor.
I worked with the application information (Figure 1 in the datasheet) but I have some problems and some questions about it.
Why Aout2 and Bout2 are the same signal delayed from TDB ?
I want to understand why,
* on the one hand AOUT1 and AOUT2 do not control the top left PMOS transistor and the bottom right NMOS transistor during the same time and
* on the other hand BOUT1 and BOUT2 do not control the top right PMOS transistor and the bottom left NMOS transistor during the same time
the problem I have is for a positive command in RG1 connected to INV, I measure 1.5A in RS2 and 0.6A in RS1 instead of zero
In a second post I can give you the Vgs and Vds for each 4 transistors.
Thank you for your help
