Texas Instruments DRV8860 Octal Low-Side Driver
Texas Instruments DRV8860 Octal Low-Side Driver provides an 8-channel low-side driver with overcurrent protection and open/shorted load detection. It has built-in diodes to clamp turnoff transients generated by inductive loads. This device can also drive unipolar stepper motors, DC motors, relays, solenoids, or other loads. The PWP package can supply up to 330mA × eight-channel, and the PW package can supply up to 200mA × eight-channel continuous output current. A single channel can deliver up to 560mA continuous output current. A serial interface is provided to control the DRV8860 output drivers, configure the internal setting register and read the fault status of each channel. Texas Instruments DRV8860 can be daisy-chained together to use a single serial interface. Energizing-time and holding-PWM-Duty cycles are configurable through the serial interface as well. These functions allow for cooler running than always-on solutions.Features
