DRV2605LYZFR is a motor driver controller, developed by Texas Instruments, for haptic feedback control of low-power, small-outline fan motors. The chip provides an integrated solution for four-wire haptic motors, allowing designers to quickly add haptics to their products.

The DRV2605LYZFR has two basic operating modes: open-loop and closed-loop. In open-loop mode, the device controls vibration based on input waveforms, while in closed-loop mode, the device provides real-time feedback on motor response quality. Both modes offer design flexibility, allowing well-controlled motor operations. In both modes, the DRV2605LYZFR uses the PWM signal input to control motor intensity, frequency, and phase. It also features a number of control registers, which allow the user to program the motor parameters.

The DRV2605LYZFR has a variety of applications in the consumer electronics, automotive, aerospace, and medical industries. In consumer electronics, it is often used in haptic feedback systems, touchpad and button interfaces, and mobile device vibration. In the automotive field, the chip is used for haptic feedback systems in steering wheels, gear shifters, and throttle and brake pedals. In the aerospace sector, it is used to control the speed and vibration of fans and actuators in aircraft. In the medical industry, it is often used for haptic feedback for prosthetics, as well as for controlling pumps, atomizers, and medical instruments.

The DRV2605LYZFR is an integrated motor driver, which means there is no need to add external components to the design. This provides a cost-effective solution and helps reduce the complexity of the design. The chip has several protection features such as over-current and over-temperature protection. It also has a low-power operating mode, providing the ability to run off a single cell battery.

The DRV2605LYZFR supports control algorithms such as waveform Library Control, Open-Loop Control, and Closed-Loop Control. Waveform Library Control allows designers to pre-load the waveforms into the chip for playback, providing user-tunable waveforms for haptic feedback. Open-Loop Control is used when the user knows the target waveforms and wants to achieve a specific haptic feedback result. Closed-Loop Control gives real-time feedback on the motor response quality, allowing for accurate and repeatable results.

The DRV2605LYZFR is an optimized motor driver for haptic applications that eliminates the need for external components by providing an integrated solution. It supports a variety of control algorithms and offers multiple protection features, making it a suitable choice for a wide range of applications in the consumer electronics, automotive, aerospace, and medical industries.
