Motor Driver from Diodes Incorporated Makes Smarter Cooling Systems

Plano, Texas - June 12, 2014 - Diodes Incorporated (Nasdaq: DIOD), a leading global manufacturer and supplier of high-quality application specific standard products within the broad discrete, logic and analog semiconductor markets, today introduced the AM4964 motor driver. The AM4964 is a single- phase, full-wave, brushless DC motor driver that operates from a 12V supply and delivers a peak motor current of up to 1A. By enabling the speed of fans, blowers and extractors to be simultaneously controlled by both PWM and thermistor input signals, the AM4964 helps create more responsive cooling systems for PCs, servers and industrial instrumentation.

The motor speed varies between low and high temperature set-points in response to the ambient temperature and the PWM input signal. The low and high temperature set-points, as well as the maximum PWM output, are easily adjusted using just three external resistors. The device also offers a tachometer output, a bias output for a differential unbuffered Hall sensor and dedicated inputs for 3- or 4-pin Hall sensors for rotor position detection.

Featured in the TSSOP-20EP package, the AM4964 is a highly integrated device and includes: a built-in oscillator, removing the need for an external capacitor; a minimum speed-setting circuit; and adjustable alpha slope technology to support different speed curve requirements. To protect the motor coil, the driver incorporates thermal shutdown, rotor lock detection and auto-restart functions. For further information, visit the Company's website at www.diodes.com.
