Key Technology Deep Dive

1. Haptic Feedback: Restore Real Physical Interaction

Haptic feedback simulates touch via motors/vibration components (e.g., impact in action games, gun recoil in shooting games, road conditions in driving games). It significantly improves immersion, precision, and fun.

Awinic’s Linear Motor Driver Chip (AW86937 Series)

Category Specifications
Basic Performance 1MHz high-speed I2C; 8KB memory; sampling rates (8/12/24/48kHz)
Functional Modules Signal processing (F0 detection + auto-braking); 6 playback modes (real-time/memory/I²S input, etc.)
Power Management Boost up to 11V; <1ms fast startup; 2.7V-5.5V operating voltage; 4μA standby current
Protection Short-circuit/overheating/undervoltage protection

2. Shoulder Buttons (LB/RB/LT/RT): Linear Hall Detection

Uses magnetic field changes to identify button position/pressure (e.g., light press = single-shot, heavy press = continuous fire in shooting games). Advantages: high precision, long lifespan, fast response.

Awinic’s Linear Hall Sensor (AW8656XDNR Series)

Category Specifications
Basic Parameters 2.5V-5.5V operating voltage; <1μA sleep current; <2.3mA operating current
Sensitivity 4 adjustable levels: 1.25/2.5/5.0/10mV/G (adapts to different scenarios)
Accuracy Linearity error <±1.5%; noise peak-to-peak <30mVpp
Customization Magnetic field simulation + structural stacking design guidance

3. Function Buttons (A/B/X/Y): Magnetic Switch Solution

Magnetic switches outperform conductive rubber:

Awinic’s Magnetic Sensor Chip (AW86562XASTR)

Category Specifications
Basic Parameters Single-stage (S-pole) detection; <15μs response speed; -40°C~+150°C operating temp
Magnetic Threshold Operate point (Bop): 35G; Release point (Brp): 20G
Output Type Open-drain (OUTS pulls low when B>BopS; high-impedance when B<Brp)

Working Principle: When a strong south-pole magnetic field is present, OUTS turns on (low level); turns off (high level via external pull-up) when the field weakens.

5. Multi-Color LED Driver: Immersive Light Effects

RGB lights on handles serve 3 key roles:

  1. Battery indicator (blue/green = full; orange/red = low)
  2. Player differentiation (multiplayer games)
  3. Game state feedback (e.g., red flash when character is injured)
