PLANO, Texas -- December 18, 2013

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 a
single-chip IC for driving single-coil reversible DC fans and motors. A highly
integrated device, in a choice of SO8 and thermally enhanced SO8 exposed pad
packages, the ZXBM5210 reduces component count and circuit footprints in
medium voltage, low-power applications in consumer, domestic appliance,
industrial and office equipment.

The driver’s integrated high-performance H-bridge output stage can deliver
currents as high as 700mA continuous, 1.2A peak and has been designed to meet
stringent low noise requirements by minimizing both audible switching noise
and electromagnetic interference. Its generous supply range of 3V to 18V means
the device will support a wide variety of single phase 5V, 9V, 12V and 15V DC
motors. Typical operating current is a low 0.85mA.

Achieving highly linear speed control, the ZXBM5210 has four modes of
operation: forward, reverse, brake and standby, which are selected via the
device’s FWD and REV input pins. Motor speed is regulated by modifying the
duty ratio of PWM signals applied to the two inputs or by adjusting the DC
input voltage to the V[REF] input pin. The PWM oscillator is integrated within
the device and no external timing capacitor is required.

The ZXBM5210’s standby mode consumes a typical current of only 32µA, thus
improving motor driving power efficiency. To prevent damage to either the
motor coil or driver IC, the ZXMB5210 incorporates under-voltage lockout,
over-voltage, over-current and thermal shutdown protection functions. Product
reliability and robustness is further enhanced by the devices’ high ESD
withstand capability of 6kV and wide operating temperature range of -40ºC to
+105ºC. For further information, visit the Company’s website at
