NPA Number 001 New Product Announcement AH5792 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 AH5792 has an integrated bidirectional full bridge driver output stage for single coil fan motor applications. The device includes features such as Rotor Lock Protection, with rotor lock detection and automatic selfrestart, to avoid damage to the coil when the rotor is locked. The AH5792 provides opendrain frequency generator (Tachometer) pin, FG, which makes it easier to interface with external hardware for status and speed monitoring purposes. The FG frequency is half (1/2) the magnetic change frequency. The AH5792 is now available in SOT89-5L in addition to SOT553. 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 driver Improved 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 www.diodes.com NPA Number 001 New Product Announcement AH5792 AH5792 smart fan driver with internal Hall sensor for single phase brushless DC motor Electrical characteristics Operating Voltage (V) Average output current (mA) IC supply current (mA) Operating Point Bop (Gauss) Release Point Brp (Gauss) Operating Temperature (°C) Package AH5792-ZG-7 1.8 to 5 200 3.5 50/10 -10/-50 -40 to 100 SOT553 AH5792-YG-13 1.8 to 5 300 3.5 50/10 -10/-50 -40 to 100 SOT89-5L Part Number To find out more information: Product page: Datasheet: http://www.diodes.com/products/catalog/list.php?parent-id=117 http://www.diodes.com/datasheets/AH5792.pdf www.diodes.com NPA Number 001 New Product Announcement AH5792 AH5792 smart fan driver with internal Hall sensor for single phase brushless DC motor Product portfolio Operating Voltage (V) Average Output current (mA) Operating Point Bop (Gauss) Release Point Brp (Gauss) Operating Temperature (°C) Package AH284 3.8 to 20 500 5/60 -5/-60 -40 to 100 SOT89-5L AH285 3.8 to 20 500 5/60 -5/-60 -40 to 100 SOT89-5L AH286 3.8 to 20 500 5/60 -5/-60 -40 to 100 SOT89-5L AH287 3.8 to 28 400 5/60 -5/-60 -40 to 100 SIP4-L SOT89-5L AH288 3.8 to 28 400 5/60 -5/-60 -40 to 100 SOT89-5L AH289 3.8 to 28 400 5/60 -5/-60 -40 to 100 SOT89-5L AH291 1.8 to 5.75 400 5/60 -5/-60 -20 to 100 SIP4-L AH292 1.8 to 5.75 400 5/60 -5/-60 -20 to 100 SOT89-5L AH293 1.8 to 5.75 400 5/60 -5/-60 -20 to 100 SOT89-5L AH2984 3.8 to 20 400 5/60 -5/-60 -40 to 100 SIP4-L AH5771 2.5 to 15 400 10/50 -10/-50 -40 to 100 SIP4-L AH5792 1.8 to 5 200 300 5/60 -5/-60 -40 to 100 SOT553 SOT89-5L Part Number Ordering information Device Packaging Pack mark Reel size Tape width Quantity AH5792-ZG-7 SOT553 KE YWX 7” 178mm 8mm 3000 AH5792-YG-13 SOT89-5L KF YWX 13” 330mm 12mm 2500 All variants are in packages that are “Green” Molding Compound (No Br, Sb) with Lead Free Finish/RoHS Compliant (Note 1) Notes: 1.
