The 1V minimum represents 100% PWM drive and 2V represents 0% PWM drive.
This voltage is determined by an internal resistor network of 52.5k⍀ from the pin to Gnd and 19.5k⍀ from the pin to a 2V reference. Whilst both
resistors track each other the absolute values are subject to a Ϯ20% manufacturing tolerance.

Pin Functional Descriptions
5. GND - Ground
1. VCC - Applied voltage
This is the device supply ground return pin and will
generally be the most negative supply pin to the fan.
This is the device 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.
6. LOCK/FG
- Locked Rotor error output /
Frequency Generator (speed) output
On the ZXBM2001 the Lock/FG pin is designed to be a
dual function pin to provide an indication of the Fans
rotational speed together with an indication of when
the Fan has failed rotating for whatever reason (Rotor

3. H-
- Hall input
- Hall input
The rotor position of the Fan Motor is detected by a Hall Locked condition). The pin is an open collector drive,
sensor whose output is applied to these pins. This that is there is an active pull down with the high level
sensor can be either a 4 pin ‘naked’ Hall device or a 3 being provided by an external pull up resistor. Under
pin buffered switching type. For a 4 pin device the correct operating conditions, and with this external
differential Hall output signal is connected to the H+ pull-up in place, this pin will provide an output signal
and H- pins. For a 3 pin buffered Hall sensor the Hall whose frequency will be twice that of the rotational
device output is attached to the H+ pin whilst the H- pin frequency of the fan. Should the fan itself stop rotating

- Speed control voltage input
remain high until the fan blades start rotating again.
This pin provides control over the Fan Motor speed by
varying the Pulse Width Modulated (PWM) drive ratio
at the Ph1 and Ph2 outputs. This control signal can take
the form of either a voltage input of nominal range 2V
to 1V, representing 0% to 100% drive respectively, or
alternatively a thermistor can be attached to this pin to
control the voltage. The pin has an internal potential
divider between Gnd and an internal 2.0V reference
designed to hold the pin at approximately 1.5V. This
will represent a drive of nominally 50%. The addition of
a 100k NTC thermistor to ground, for example, will
provide a drive nominally 70% at 25°C and 100% at
50°C.
On the ZXBM2002 variant this pin is Lock. During
normal operation the signal will be low and during a
Locked Rotor condition the pin will go high when the
C
pin reaches the V
threshold.

THH
For the ZXBM2003 variant this pin is FG. This signal is a
buffered and inverted output of the Hall signal and
therefore provides an output signal whose frequency
willbetwicethatoftherotational frequency ofthefan.
7. C
- Locked Rotor timing capacitor
LCK
When in a Locked Rotor condition as described above
the Ph1 and Ph2 drive outputs go into a safe drive mode
to protect the external drive devices and the motor
windings. This condition consists of driving the motor
for a short period then waiting for a longer period
before trying again. The frequency at which this takes
place is determined by the size of the capacitor applied
to this CLCK pin. For a 12V supply a value of 1.0uF will
typically provide an ‘On’ (drive) period of 0.33s and an
‘Off’(wait)periodof4.0s, givinganOn:Off ratioof1:12.
If speed control is not required this pin is can be left
open circuit for 50% drive or tied to ground by a 10k⍀
resistor to provide 100% drive.
If required this pin can also be used as an enable pin.
The application of a voltage of 2.0V to V will to force
CC
the PWM drive fully off, in effect disabling the drive.

APPLICATION INFORMATION
The ZXBM200x series of 2-phase DC brushless motor Also illustrated in the two Applications circuits above
pre-drivers are capable of driving both Bipolar or are the methods of connection for both a ‘naked’ Hall
MOSFET power transistors.
device, as seen in the bipolar circuit in Figure 1, and a
buffered Hall device, as in the MOSFET circuit in Figure
2. In this latter circuit R5 & R6 bias the H- pin at a voltage
equivalent to half the swing of the Hall device. R7 will
be needed if the buffered Hall device does not have its
own internal pull-up.
For smaller fans and blowers it is likely that bipolar
power transistors would be used as shown in the
following Applications circuit.
In Figure 1, R1 & R2 have their value selected to provide
suitable base current in keeping with the winding
current and gain of the power transistors Q1 & Q2. R3 &
R4 have their value selected to provide efficient
switch-off of Q1 & Q2. The Zener diodes ZD1 & ZD2
provideactiveclamping inconjunction withQ1&Q2.
TYPICAL APPLICATION (ZXBM2001) using
MOSFET power transistors
It is also recommended that the supply de-coupling
capacitor C3 is positioned as close as is practical to the
ZXBM device pins.
TYPICAL APPLICATION (ZXBM2001) using
Bipolar power transistors
Figure 2
Graph 1 below, illustrates the PWM drive waveform
taken from and application using the MOSFET circuit in
Figure 2. This shows the waveforms to be found at the
Ph1 output and at the drain/Winding node.
Figure 1
In the case of higher power fans and blowers it may be
more applicable to use MOSFET devices to switch the
windings as illustrated in the second applications
circuit shown in Figure 2.
In Figure 2, the Resistor ratio of R1 to R3 and R2 to R4
provide the required Gate turn-on voltage whilst the
absolute values will be chosen to provide sufficient
gate switching currents.

When driving fans with bipolar transistors, at higher
voltages it may be necessary to provide extra noise
protection by the addition of a diode from the driver
collector to Gnd on each phase. This prevents negative
voltage excursions from the windings affecting
operation. See Figure 3 right, showing the placement
of these diodes. It should be noted that these are not
required for the MOSFET solution in Figure 2 as the
diodes are inherent in the MOSFET structure.
TYPICAL APPLICATION (ZXBM2001)
illustrating addition of Clamp diodes.
Zetex provide a variety of suitable power transistors for
using with the ZXBM200x series of 2-phase DC
brushless motor pre-drivers and suitable devices
sufficient for a range of applications are given in the
