Because the PI40952 uses logic inputs, you can implement speed control by enabling/disabling the channel rapidly using PWM on the EN pin OR by toggling one of the input bits. The cleaner method is using the enable pin:
delay(1000); for (int i = 100; i >= 0; i--) setSpeed(i); delay(20); pi40952 3x2b driver
| Part Number | Channels | Control Type | Voltage | Current | Compatibility | |-------------|----------|--------------|---------|---------|----------------| | | 2 | 2x2B | 50V | 6A | Needs external logic for 3rd channel | | L6206 | 2 | 2x2B | 52V | 5.6A | Dual channel only | | TB6612FNG | 2 | 2x2B | 15V | 3.2A | Low voltage, not a direct replacement | | BD6231 | 1 | 2B | 32V | 3A | Use three ICs for 3 channels | | MC33887 | 1 | 2B | 40V | 5A | Robust, but single channel only | Because the PI40952 uses logic inputs, you can
void motorStop() digitalWrite(A1, LOW); digitalWrite(A2, LOW); // Coast mode Because the PI40952 uses logic inputs
motorStop(); delay(1000);
void motorBrake() digitalWrite(A1, HIGH); digitalWrite(A2, HIGH);
