Self-clearing
When the "Latched" conditions happen, the device must be reset with the EN signal in order to clear the fault. If
automatic recovery from these conditions is desired, connect the INTZ pin directly to the EN pin. This allows the
INTZ pin function to automatically drive the EN pin low which clears the latched condition.
7.4 Device Functional Modes
The DRV2511-Q1 device has multiple power states to optimize power consumption.
7.4.1 Operation in Shutdown Mode
The NRST pin of the DRV2511-Q1 device puts the device in a shutdown mode. When NRST is asserted (logic
low), all internal blocks of the device are off to achieve ultra low power.
7.4.2 Operation in Standby Mode
The STDBY pin of the DRV2511-Q1 device puts the device in a standby mode. When STDBY is asserted (logic
high), some internal blocks of the device are off to achieve low power while preserving the ability to wake up
quickly to achieve low latency waveform playback.
7.4.3 Operation in Active Mode
The DRV2511-Q1 device is in active mode when it has a valid supply, and it is not in either shutdown or standby
modes. In this mode the DRV2511-Q1 device is fully on and reproducing at the output the input times the gain.
7.5 Programming
7.5.1 Gain
The DRV2511-Q1 device has a configurable gain that is controlled through external resistors. Please see the
Analog Input and Configurable Pre-amplifier section for more details.
