MAX11835EWA+T

The Analog Devices MAX11835EWA+T is an efficient, high-voltage haptic actuator controller featuring an I2C interface. It provides a complete solution for driving haptic actuators, including single-layer and multilayer piezo types, to create custom haptic sensations. The device efficiently generates user-programmable waveforms such as sine waves, trapezoidals, squares, and pulses.

The MAX11835 integrates a boost regulator capable of generating high-voltage waveforms up to 250V, essential for driving haptic actuators effectively. It supports an 8-bit resolution for piecewise linear data storage, allowing for detailed control over haptic feedback patterns. The controller operates within a digital supply voltage range of 1.7V to 3.6V and an analog/boost supply range of 2.7V to 5.25V.

This controller is suitable for applications requiring tactile feedback, such as mobile communication devices, PDAs, media players, notebooks, e-readers, and handheld gaming consoles. It features smart low-power and standby modes to reduce power consumption. The device is available in a compact 25-WLP (2.31x2.31) package, designed for surface mounting.

Key features include user-programmable waveform generation, on-chip waveform storage, and a fast 400kHz I2C serial interface for easy programming and status checking. The MAX11835 is designed to integrate seamlessly with application processors or host controllers, offering a versatile solution for enhancing user interaction through haptic feedback.
