Hi, I am thinking about using L6205 SO20 type for mini sumo robot project, I thought ina and inb pins are for pwm but I am not sure. How can I control 2 motors with different speeds using this driver? Thanks a lot :))
Seems like a nice chip.
The data sheet explains how it works, with all the required details. Whether it will work with your motors depends on their characteristics.
The truth table for the input pins is in the datasheet, basically each controls one half-H-bridge. The driver is agnostic about PWM or whatever, it just switches immediately.
