I need to control two 12v motors that draw ~8 amps each. They are going to be throttled way down using PWM and PID control, I only really need 20% or so of their output, but I can not change them for better motors. Now I already have some nice half-bridge chips in my parts drawer, BTN7970P. Since I …
