SLOS825E December 2012 – April 2018 DRV2605
The DRV2605 device contains nonvolatile, on-chip, OTP memory for specific configuration parameters. When written, the DRV2605 device retains the device settings in registers 0x16 through 0x1A including after power cycling. This retention allows the user to account for small variations in actuator manufacturing from unit to unit as well as to shorten the device-initialization process for device-specific parameters such as actuator type, actuator-rated voltage, and other parameters. An additional benefit of OTP is that the DRV2605 memory can be customized at the device-test level without driving changes in the device software.
