SLOS854D May 2014 – March 2018 DRV2605L
If an I2C stops unexpectedly, the possibility exists for the I2C protocol to remain in a hanged state. To allow for the recovery of the communication without having to power cycle the device, the DRV2605L device includes an automatic watchdog timer that resets the I2C protocol without user intervention after 4.33 ms. This behavior happens in all conditions except in standby mode. If the I2C stops unexpectedly during standby mode, the only way to recover communication is by power-cycling the device.
