ADUX1001i

Data Sheet FEATURES Smart Linear Resonant Actuator Controller ADUX1001i GENERAL DESCRIPTION The ADUX1001i is a high efficiency linear resonant actuator (LRA) controller that uses the Analog Devices, Inc., proprietary Actuator Response Control™ (ARC™) technology. The ADUX1001i control algorithm detects LRA resonant fre quency and provides closed-loop control of drive frequency and magnitude, ensuring compelling, reliable, and repeatable haptic effects for all portable, gaming, and handheld applications. The ADUX1001i features an 8-bit digital-to-analog converter (DAC) that has programmable, bi-directional output current capability. The hardware shutdown mode ensures low power operation over a full 2.3 V to 4.8 V supply range, making it ideally suited for portable mobile device haptic applications. The ADUX1001i is compatible with Immersion TS3000 and Immersion TS4000 engines. The ADUX1001i features three interface options ensuring that the ADUX1001i can be used in existing haptic implementations as well as in new low latency haptic implementations. The operating modes of the controller are invoked by the ADUX1001i using a PWM- and/or an I2C-compatible interface. The I2C 7-bit address for the ADUX1001i is programmable using two external pins. ARC enabled LRA automatic resonance detection and magnitude control Agile pattern generator enabling HD haptic effects Fast start and sharp braking PWM and I2C drive modes Low latency response (LLR) drive mode Compatible with Immersion T...
