NOTE
Information in the following applications sections is not part of the TI component
specification, and TI does not warrant its accuracy or completeness. TI’s customers are
responsible for determining suitability of components for their purposes. Customers should
validate and test their design implementation to confirm system functionality.
8.1 Application Information
The DRV2510-Q1 device is a high-efficiency driver for inductive loads, such as solenoids and voice-coils. The
typical use of the device is on haptic applications where short, strong waveforms are desired to create a haptic
event that will be coming from the application processor.
8.2 Typical Applications
8.2.1 Single-Ended Source
To use the DRV2510-Q1 with a single-ended source, apply either a voltage divider to bias INB to 3 V, tie to GND
or use a 0.1-μF cap from INB to GND to have the device self bias. Apply the single-ended signal to the INA pin.
