DRV8860PW

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.

Warnings

This device has limited built-in ESD protection, leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
