JAJSCX0C October 2015 – November 2018 DRV8885
PRODUCTION DATA.
The DRV8885 decay mode is selected by setting the quad-level DECAY pin to the voltage range in Table 6.
DECAY | INCREASING STEPS | DECREASING STEPS |
---|---|---|
100 mV
Can be tied to ground |
Slow decay | Mixed decay: 30% fast |
300 mV, 15 kΩ to GND | Mixed decay: 30% fast | Mixed decay: 30% fast |
1.0 V, 45 kΩ to GND | Mixed decay: 60% fast | Mixed decay: 60% fast |
2.9 V
Can be tied to DVDD |
Slow decay | Slow decay |
Increasing and decreasing current are defined in the chart below. For the Slow/Mixed decay mode, the decay mode is set as slow during increasing current steps and mixed decay during decreasing current steps. In full step mode the decreasing steps decay mode is always used.
