The DRV2605YZFR is a dual-channel, haptic motor driver and controller. It is a PMIC motor driver that is capable of driving various haptic motor types using various motor types and voltage ratings. This motor driver is designed to enable haptic feedback in products such as smartphones, wearables, tablets, gaming devices, and other electronics devices. Its features, such as its low power requirements, excellent noise immunity, and variable voltage output make it an ideal choice for a wide range of applications.

The DRV2605YZFR includes two independent channels, one for a braille actuator and the other for an ERM (Eccentric Rotating Mass) actuator or a linear actuator. The two channels are powered by a single supply voltage, which ranges from 5V to 15V, with a 5V to 24V input voltage range to give flexibility to the design. The DRV2605YZFR also includes a wide selection of preset waveforms and a comprehensive library of effect waveforms for designing creative haptic effects.

When used with an ERM/Linear haptic motor, the DRV2605YZFR can deliver various waveforms with high fidelity, such as sinusoidal waveforms, square waveforms, and triangular waveforms. These waveforms can be customized to match the specific characteristics of the motor, allowing for optimal haptic feedback. The DRV2605YZFR also features a variety of advanced features, including a “safe-touch” mode, and a “safe-start” mode, to ensure that the motor operates safely.

When used with a Braille actuator, the DRV2605YZFR provides two independent waveforms for operation in combination with the Braille dots. With its two waveforms, the DRV2605YZFR can provide up to three supported tactile feedback effects from a single Braille actuator. The DRV2605YZFR also features an advanced audio-dedicated module, which enables precise control of the audio/speech system to deliver a precise Braille reading experience.

In addition to its support for various motor types and waveform control, the DRV2605YZFR also features advanced motor control functions, such as overcurrent protection, adjustable back-EMF detection levels, and software-selectable operation modes. The DRV2605YZFR also includes intelligent diagnostics and controls, allowing for proper fault management and safe operation.

The DRV2605YZFR is an ideal solution for haptic feedback applications in smartphones, tablets, wearables, gaming devices, and other consumer electronics devices. Its wide selection of waveforms, combined with its low power requirements, excellent noise immunity, adjustable voltage levels, and advanced motor control functions make it an ideal choice for creating creative haptic feedback in many applications.
