(HUNGARYNEWSWIRE.COM, November 28, 2008 ) Hong Kong - Diodes Incorporated has introduced a single chip solution providing all the functionality required for driving low power single coil brushless DC fans and motors. The AH5792 integrates a Hall sensor and amplifier, complete digital control circuitry and a full bridge output driver in the low profile SOT553 package and will appeal in particular to low voltage micro-motors and ultra thin cooling fan applications.
With its bi-directional, H-bridge output stage, the AH5792 suits single-phase full wave brushless DC motor control, by offering a pair of push-pull output drivers to source and sink current. The device operating voltage range of 1.8V to 5V also caters for low operating voltage miniature DC fans requiring low voltage start-up.
To protect motor windings from damage, the new motor controller includes integrated locked rotor detection and automatic self restart functions which serve to shutdown the output driver in the event of a locked rotor and then restart the motor when the rotor is freed. In addition, a frequency generator output provides users with tachometer-like feedback for external speed monitoring. The all-in-one smart motor controller eliminates the need for external components including a timing capacitor.
The AH5792 has an operating temperature range of –40C to 100C and is fully RoHs complaint with Green molding compound.
