●The DRV8860PW is a low-side Octal Driver with serial interface. It has built-in diodes to clamp turn-off transients generated by inductive loads and can be used to drive unipolar stepper motors, DC motors, relays, solenoids or other loads. A single channel can deliver up to 560mA continuous output current. A serial interface is provided to control the DRV8860 output drivers, configure internal setting register and read the fault status of each channel. This driver can be daisy-chained together to use a single serial interface. Energizing-time and holding-PWM-Duty cycles are configurable through serial interface as well. These functions allow for cooler running than always-on solutions. Internal shutdown functions are provided for over-current, short-circuit, under-voltage lockout and over-temperature protection. The driver does not include open load detection. Fault information for each channel can be read out through serial interface and indicated by an external fault pin.
