The reference voltage of the comparator can be set to a fixed voltage or to the center pin.
The saturation of the ballast choke means that a very high current flows into the resonant network and the almost instantaneous modification of the resonant curve occurs immediately at the operating point in capacitive mode.
PWP Encapsulation: 2-A (Single Channel Enabled) / 1-A (Quad Channel Enabled) Maximum Drive Current per Channel (25°C, Adequate PCB Heat Dissipation)
DRV8805 is an integrated 4-channel unipolar stepper motor driver with a stepper/directional interface,
Enable or disable the output driver for the eNBL pin. The nNBL must be low to enable output. NNBL does not affect the operation of serial interface logic.
