AH5792 smart fan driver with internal Hall sensor for single phase brushless DC motor
Description
The AH5792 is a highly integrated single chip solution for driving single-phase brushless DC (BLDC) fans and motors.
The Diodes advantage
The AH5792 provides highly integrated yet simple low cost effective solution for cooling fans and motor drives
■ Built-in Hall sensor and amplifier All-in-one integrated solution drastically reduces external component count.
■ Integrated bidirectional full bridge driver Supports source and sink current for single phase motor driver operation up to 300mA average load current. No external driver components – reduced PCB area
■ Lock detection and automatic self-start, without external capacitor Protects coil from over-heating or burn-out during motor/fan lockout Reduces number of external components
■ Packages: SOT895-L and SOT553 (Available in “Green” Moulding Compound) Provides low pin count SMT BLDC fans/motor driverImproved thermal performance and higher current with SOT89-5L Low profile small footprint with SOT553 for space constrained needs
APPLICATIONs
■ 3.3/5V BLDC cooling fan LED driving
■ Low voltage/low power BLDC motors
■ Micro-vibrating motors
