TWO PHASE VARIABLE SPEED
MOTOR CONTROL PRE-DRIVER
Functional Descriptions
H+ and H- Hall Inputs
The rotor position is detected by a Hall sensor, with the output applied to the H+ and H-pins. This sensor can be either a 4 pin
'naked' Hall device or of the 3 pin buffered switching type. For a 4 pin device the differential Hall output signal is connected to
the H+ and H-pins. For a buffered Hall sensor the Hall device output is attached to the H+ pin, with a pull-up attached if
needed, whilst the H-pin has an external potential divider attached to hold the pin at half VCC. When H+ is high in relation to
H-, Ph2 is the active drive.
ThRef - Output Reference Voltage
This is a reference voltage of nominal 3V. It is designed for the ability to 'source' and therefore it will not 'sink' any current
from a higher voltage. The current drawn from the pin by the minimum speed potential divider to pin SMIN and any voltage
setting network should not exceed 1mA in total at maximum temperature.
SPD - Speed Control Input
The voltage applied to the SPD pin provides control over motor speed by varying the Pulse Width Modulated (PWM) drive
ratio at the Ph1 and Ph2 outputs. The control signal takes the form of a voltage input of range 3V to 1V, representing 0% to
100% drive respectively.
If variable speed control is not required this pin can be left with an external potential divider to set a fixed speed or tied to
ground to provide full speed i.e. 100% PWM drive.
If required this pin can also be used as an enable pin. The application of a voltage >3.0V will force the PWM drive fully off, in
effect disabling the drive.
SMIN – Minimum Speed Setting
A voltage can be set on SMIN pin via a potential divider between the ThRef and Gnd. This voltage is monitored by the SPD
pin such that internally SPD voltage cannot rise above SMIN voltage. As a higher voltage on the SPD pin represents a lower
speed it therefore restricts the lower speed range of the fan. If this feature is not required the pin is left tied to ThRef so no
minimum speed will be set.
If the fan is being controlled from an external voltage source onto the SPD pin then either this feature should not be used or if
it is required then a resistor greater than 1kΩ should be placed in series with the SPD pin.
CPWM – Output PWM Frequency Setting
This pin has an external capacitor attached to set the PWM frequency for the Phase drive outputs. A capacitor value of 0.1nF
will provide a PWM frequency of typically 24kHz. The CPWM timing period (TPWM) is determined by the following equation:
(
VTHH − VTHL
)
× C
(
VTHH − VTHL × C
)
TPWM =
+
IPWMC
IPWMD
Where: C = (CPWM +15) in pF
VTHH and VTHL are the CPWM pin threshold voltages
IPWMC and IPWMD are the charge and discharge currents in µA.
TPWM is in ms
As these threshold voltages are nominally set to VTHH = 3V and VTHL = 1V the equations can be simplified as follows:

TPWM =

TWO PHASE VARIABLE SPEED
MOTOR CONTROL PRE-DRIVER
Functional Description (cont.)
CLCK - Locked Rotor Timing Capacitor
Should the fan stop rotating for any reason, i.e. an obstruction in the fan blade or a seized bearing, then the device will enter
a Rotor Locked condition. In this condition after a predetermined time (TLOCK) the RD pin will go high and the Phase outputs
will be disabled. After a further delay (TOFF) the controller will re-enable the Phase drive for a defined period (TON) in an
attempt to re-start the fan. This cycle of (TOFF) and (TON) will be repeated indefinitely or until the fan re-starts.
GND – Supply Return
This is the device supply ground return pin and will generally be the most negative supply pin to the fan.
RD - Rotor Lock Detect Output
This pin is the Locked Rotor status output as referred to in the CLCK timing section above. It is high when the rotor is stopped
and low when it is running.
This is an open collector drive giving an active pull down with the high level being provided by an external pull up resistor.

Functional Descriptions (cont.)
FG -Frequency Generator (tachometer) Output
This is the Frequency Generator output and is a buffered signal from the Hall sensor.
This is an open collector drive giving an active pull down with the high level being provided by an external pull up resistor.
Ph1 and Ph2 Output Drives
This pair of outputs drives the external devices. These outputs provide both the commutation and PWM waveforms. The
outputs are of the Darlington emitter follower type with an active pull-down to help faster switch off when using bipolar
devices. When in the high state the outputs will provide up to 80mA of drive into the base or gates of external transistors as
shown in the Typical Application circuit following.
When in the low state the active Phase drive is capable of sinking up to 16mA when driving low to aid turn off times during
PWM operation. When the Phase is inactive the output is held low by an internal pull-down resistor.
V+OP Phase Outputs Supply Voltage
This pin is the supply to the Phase outputs and will be connected differently dependant upon external transistor type. For
bipolar devices this pin will be connected by a resistor to the VCC pin. The resistor is used to control the current into the
transistor base so its value is chosen accordingly. For MOSFET devices the pin will connect directly to the VCC pin.
VCC – Supply Voltage
This is the device internal circuitry supply voltage. For 5V to 12V fans this can be supplied directly from the Fan Motor supply.
For fans likely to run in excess of the 18V maximum rating for the device this will be supplied from an external regulator such
as a Zener diode.

TWO PHASE VARIABLE SPEED
MOTOR CONTROL PRE-DRIVER
Application Note
The ZXBM2004 is primarily controlled by a voltage on the SPD pin. A voltage of 1V represents a 100% PWM at the Phase
Outputs and in turn represents full speed. 3V on the SPD pin conversely represents 0% PWM. The motor can therefore be
controlled simply by applying a control voltage onto the SPD pin with the minimal use of external components.
This voltage control method easily lends itself to control by other signal types. For example if a Thermistor is applied to the
SPD pin a varying voltage can be generated at the SPD pin as the resistance of the Thermistor varies with temperature.
A common form of control of fans is by a PWM signal derived from a central processor or controller. This signal can be
converted into a voltage and that voltage adjusted as necessary to compensate for motor none linearity, inclusion of the
Minimum speed feature etc.
Full applications details and further examples of how to control the ZXBM2004 are available in the Applications Notes AN41,
AN42 and AN43.
