Output ON Resistance Figure 2. VM Operating Supply Current 8 Detailed Description 8.1 Overview The DRV8860 is an integrated 8-channel low side driver with overcurrent protection and open/short detection. 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. DRV8860 can supply up to 200 mA x 8 channel continuous output current. The current driving capability increases with lower PWM duty cycle. A single channel can deliver up to 560 mA continuous output current. Refer to the current capability table for details. A serial interface is provided to control the DRV8860 output drivers, configure internal register settings, and read the fault status of each channel. Multiple DRV8860 devices can be daisy-chained together to use a single serial interface. Energizing-time and holding-PWM-duty cycle are configurable through the serial interface as well. These functions allow for cooler running than traditional always-on solutions. Internal shutdown functions are provided for overcurrent protection, short-circuit protection, under voltage lockout and over temperature. DRV8860 can diagnosis an open load condition. DRV8860A does not include open load detection. Fault information for each channel can be read out through serial interface and is indicated by an external fault pin.
