PSOC™ Control C3 + CoolGaN™ Drive for motor control

Build next gen high speed BLDC hair dryers with PSOC™ Control C3 MCUs + CoolGaN™ Drive GaN IPS—more power, higher efficiency, lower noise, and a smaller footprint.

Why this combination? It is aligned with design trends:

  • Three phase motors, DSP based control, sensorless FOC
  • Fsw moving from ~4 kHz to >40 kHz

PSOC™ Control C3:

  • Real time loops: 12 MSPS ADC (16 parallel S/H) and a Trigger Matrix linking ADC/timers/comparators for µs level response
  • Hardware acceleration: DSP/FPU/CORDIC; 240 MHz timers with 80 ps PWM resolution for ultra fine duty control
  • WBG ready precision and low standby power; rapid development via ModusToolbox Motor & Power Suite; PSA L2 security for OTA and key protection

CoolGaN™ Drive:

  • 50% lower switching/conduction losses vs. Si IGBT; supports higher Fsw with better efficiency and thermals
  • Smooth dv/dt reduces EMI and filtering—often eliminating multiple HV phase capacitors
  • Integrated IPS/IPM simplifies the power stage, shrinking PCB and BOM while boosting reliability

Together, they deliver precise sensorless FOC at high RPM, refined airflow with reduced acoustic noise, higher power density, and a faster path from prototype to production.

Sensors for hair dryers and stylers

Infineon offers a huge array of sensors, which bring intelligence, unparalleled user safety, and premium UX to modern hair dryers and stylers. Examples include:

  • Pressure condition monitoring: XENSIV™ pressure sensors track ΔP to detect rotor lock. Key specs: 300–1200 hPa (absolute), accuracy ±0.5 hPa.
  • Touch button/panel: CAPSENSE™ capacitive/inductive sensing for water‑tolerant HMI. Key specs: SNR >40 dB, touch latency <20 ms.
  • User activity/anomalies: XENSIV™ vibration sensors enable wake‑on‑motion and motor/filter health monitoring. Key specs: ±8 g range, up to 1 kHz bandwidth.
  • Control button: XENSIV™ 3D magnetic Hall sensor measures true 3‑axis movement for precise control. Key specs: ±130 mT range, up to 3 kHz sample rate.
  • Attachment detection: XENSIV™ linear magnetic sensors identify accessories and position. Key specs: ±32 mT range, accuracy ±1% FS.
  • Face ID recognition: REAL3™ 3D Time‑of‑Flight (ToF) solutions enable depth sensing for user profiles and hair‑type presets. Key specs: 0.2–2 m depth range, precision ±1% Z.
  • Distance measurement: REAL3™ ToF solutions safeguard scalp by monitoring dryer‑to‑head distance. Key specs: 0.1–1.0 m range, precision ±10 mm.
