DRV2605L Multiple ERM, LRA Haptic Driver Kit
1
Introduction
The DRV2605L device is a haptic driver designed for linear resonant actuators (LRA) and eccentric
rotating mass (ERM) motors. The device has many features that help eliminate the design complexities of
haptic motor control including:
•
Reduced solution size
•
High-efficiency output drive
•
Closed-loop motor control
•
Quick device startup
•
Embedded waveform library
•
Auto-resonance frequency tracking
The DRV2605LEVM-MD evaluation module (EVM) is an evaluation platform for the DRV2605LDGS. The
kit includes 8 DRV2605L devices, MSP430F5510 microcontroller (MCU), terminal output support for up
eight LRAs or ERMs, DRV2605L-integrated waveforms licensed from Immersion, and capacitive touch
buttons which demonstrate the capabilities of the DRV2605L.
This user's guide contains instructions for setting up and operating the DRV2605LEVM-MD.

  • Page 1 DRV2605L Multiple ERM, LRA Haptic Driver Kit Introduction The DRV2605L device is a haptic driver designed for linear resonant actuators (LRA) and eccentric rotating mass (ERM) motors. The device has many features that help eliminate the design complexities of haptic motor control including: •...

  • Page 2: Getting Started

    Code Composer Studio™ software. The board receives power in two ways. For applications that require two or less active DRV2605L devices device at the same time, the board can be powered through a USB port. For applications that require more than two drivers, the use of the external power supply terminals with a current rating of 1.6 A is...
  • Page 3 • B1: The DRV2605L devices are setup individually and RTP mode is configured. Sequential button presses activate the next DRV2605L device in sequential order starting at driver 1, ending at driver 8, and then looping back to driver 1. •...
  • Page 4 3.2.1 Mode 1 Mode 1 allows the user full access to all of the DRV2605L devices on the board by enabling them and connecting all of the I C lines. An external host processor can be connected to the I C headers to allow communication to the DRV2605L devices without having to use the on-board MSP430F5510.
  • Page 5 The four DRV2605L devices are sent the same default initialization settings for ERM actuators (Mode 4) and LRA actuators (Mode 5). When the settings are received by the DRV2605L devices, each DRV2605L device is individually enabled sequentially and setup for RTP mode with magnitude 0x7F at a 500-ms interval.
  • Page 6 Measurement and Analysis—Waveform Sequences The DRV2605L device uses PWM modulation to create the output signal for both ERM and LRA actuators. To measure and observe the DRV2605L output waveform, connect an oscilloscope or other measurement equipment to the filtered output test points, OUT+ and OUT–.

  • Page 10 The TCA9554 device is first configured for output ports for drivers 6 and 7 with a value of 1 at the output. The TCA9548A device is switched to driver 7 (channel 8) and sent a read command to the DRV2605L device to verify communication with the haptic driver.

  • Page 11: Power Supply Selection

    Power Supply Selection The DRV2605LEVM-MD can be powered by USB or an external power supply (VBAT). Jumpers DRV and MSP are used to select USB or VBAT for the DRV2605L and MSP430F5510 devices, respectively. Table 6 lists the different supply configurations and supply voltages that the DRV2605L devices and MSP430 device could have.
