In the field of gaming peripherals, a millisecond-level response gap can determine victory or defeat. In 2025, the Logitech G PRO X2 SUPERSTRIKE shook the industry with its HITS (Haptic Inductive Trigger System) — replacing traditional physical micro-switches with inductive analog sensing to achieve contactless triggering, reducing click latency by up to approximately 30ms, and introducing adjustable haptic feedback on a mouse for the first time. This breakthrough marks the official entry of gaming mice into the era of "programmable haptics."

From traditional micro-switches to linear motor haptic feedback, and then to electromagnetic inductive contactless triggering, every leap in click technology places higher demands on driver ICs in terms of response speed, power consumption, and vibration precision. To address the stringent requirements of gaming mice for ultra-low latency triggering, precise haptic feedback, high-precision magnetic sensing detection, long battery life, and lightweight design, AWINIC has launched a series of high-performance Haptic, Hall sensing, and supporting power solutions. These cover key components including normal-voltage motor drivers, digital linear Hall sensors, RGB ambient LED drivers, linear chargers, USB PD controllers, OVP overvoltage protection, and load switches. The specific application architecture is shown below:

AWINIC Haptic Ecosystem Capabilities

Since launching its linear motor driver ICs in 2017, AWINIC has built a complete Haptic full-chain capability covering chips, algorithms, tools, standards, and motor ecosystems, with over 700 million devices shipped globally to date.

IEEE 2861.3 Gaming Haptic International Standard

AWINIC, together with Tencent and Xiaomi, jointly initiated the IEEE 2861.3 Mobile Gaming Haptic Feedback International Standard, defining a universal haptic interface and vibration waveform description file (HE format) to address the industry pain point of inconsistent vibration feel across different devices and motors. The AW8625X series chips are the first to hardwire the IEEE 2861.3 protocol into the hardware layer, with protocol parsing and waveform computation entirely handled by the chip independently, without occupying the host MCU CPU or system memory, delivering three core advantages:

· Zero Software Adaptation: Chips are standard-compliant upon power-on, eliminating the need for protocol parsing code development at the system level.

· Offloading Platform Computing Power: Protocol processing offloaded to hardware, ensuring core tasks such as game rendering and ray tracing remain unaffected.

· Ultra-Low Latency: Hardware direct-path enables sub-millisecond haptic feedback response latency.

Chip Hardware Performance

AWINIC chips possess two core hardware-level performance advantages — the AAE Auto-Brake Engine and LCC Motor Consistency Calibration — ensuring haptic experience quality and consistency. Among them, AAE (Advanced Auto-Brake Engine) has now evolved to AAE 2.0:

· AAE 1.0: Auto-brakes at waveform end to suppress residual vibration

· AAE 2.0: Supports braking at any moment; combined with fast-start algorithm, enables "square-wave vibration" — steep rising and falling edges, crisp and clean tactile feedback, no lingering in button responses

LCC 3.0 (LRA Consistency Calibration) Motor Consistency Calibration: Due to material and process variations, LRA linear motors from the same batch exhibit significant differences in resonant frequency (F0) and vibration amplitude distribution. LCC 3.0 automatically detects each motor's F0 and adjusts driving parameters to achieve:

· Calibration Accuracy: ±1Hz

· Vibration Consistency Improvement: 50%
