Low side driver has overcurrent protection and open/shorted load detection

The Texas Instruments DRV8860 provides an 8-channel low side driver with overcurrent protection and open/shorted load 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. The PWP package can supply up to 330mA × 8 channel and The PW package can supply up to 200mA × 8 channel continuous output current. A single channel can deliver up to 560mA continuous output current. A serial interface is provided to control the device output drivers, configure internal setting register and read the fault status of each channel. These devices can be daisy-chained together to use a single serial interface. Energising-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 overcurrent protection, short-circuit protection, undervoltage lockout, and overtemperature. The device 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.
