From handheld vacuum cleaners and wireless mite removers to intelligent robotic sweepers, PTC’s three types of BLDC driver ICs deliver stable, high-efficiency and ultra-quiet drive performance for both low-power compact appliances and high-speed high-power models, perfectly satisfying performance requirements across diverse application scenarios.

✅ Solution 1: PT2502 / PT2522 Sensorless 3-Phase BLDC Controller

• Sensorless Drive Technology: Sensor-free control realized by detecting back electromotive force (BEMF) of motors to cut hardware failure points and improve equipment reliability.

• Soft-switching Noise Reduction: Proprietary trapezoidal & quasi-sinusoidal modulation drastically cuts electromagnetic noise for smoother, quieter operation.

• Wide Compatibility: Excellent tolerance to motor parameter variations ensures consistent mass production without complicated calibration.

✅ Solution 2: PT32M625 Integrated BLDC Driver MCU

• ARM Cortex‑M0 Core: Up to 48 MHz operating frequency, equipped with 32KB Flash and 4KB SRAM to execute sophisticated control algorithms effortlessly.

• SiP Packaging: System-in-Package integrates MCU and 90V gate driver into a single chip, greatly simplifying peripheral circuit layout for motor control.

• Multi-fold Protection: Built-in stall, thermal, over-current & under-voltage protection plus pulse injection positioning enables seamless soft motor startup.

✅ Solution 3: PT5619 90V 3-Phase Gate Driver IC

• 90V High-Voltage Drive: Single-chip integration of three half-bridge gate drivers to power high-current MOSFETs for high-power applications.

• Built-in Safety Features: Integrated dead-time control, shoot-through protection and under-voltage lockout safeguard half-bridge circuits from damage.

• Flexible Deployment: Works with external MCUs and supports multiple control algorithms to accommodate customized product development.
