Description
First complete version
Corrected package dimensions and motor current table
More details on: stealthChop lower current limit
Corrected: effective stealthChop PWM frequency is 2*pin frequency,
5V+-5%, ESD schematic w. varistors instead of snubber
Corrected half step table in chapter 11.2, rewording for clarity
Added –TA package, Changed order / rewording of chapter 7-9.
Corrected example 1 – drive CFG1 to GND / open
