SLOS825E December 2012 – April 2018 DRV2605
If any of the output pins (OUT+ or OUT–) is shorted to VDD, GND, or to each other while the device is playing a waveform, the OC_DETECT bit is asserted and remains asserted until the short is removed. A current-protection circuit automatically enables to shutdown the current through the short.
If the driver is playing a waveform the DRV2605 device checks for shorts in the output through either a haptic-playback, auto-calibration, or diagnostics process. If the short occurs when the device is idle, the short is not detected until the device attempts to run a waveform.
