6 Description (continued)
An I2C interface allows the user to reprogram specific motor parameters in registers and program the EEPROM
to help optimize the performance for a given application. The DRV10975 is available in a thermally-efficient
HTSSOP, 24-pin package with an exposed thermal pad. The operating temperature is specified from –40°C to
125°C.
