PIN FUNCTIONAL DESCRIPTION  
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.  
H+ - Hall input  
H- - Hall input  
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.  
SMIN - Sets Minim um Speed  
A voltage can be set on this pin via a potential divider  
between the ThRef and Gnd. This voltage is m onitored  
by the SPD pin such that it cannot rise above it. 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 m inim um 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 >1k⍀ resistor  
should be placed in series with the SPD pin.  
ThRef - Netw ork Reference  
This is a reference voltage of nom inal 3V. It is designed  
for the ability to 'source' and therefore it will not 'sink'  
any current from a higher voltage.  
CPWM - Sets PWM Frequency  
The total current drawn from the pin by the m inim um  
speed potential divider to pin SMIN and any voltage  
setting network should not exceed 1m A at m axim um  
tem perature.  
This pin has an external capacitor attached to set the  
PWM fre q u e n cy fo r th e Ph a s e d rive o u tp u ts . A  
capacitor value of 0.1nF will provide a PWM frequency  
of typically 24kHz.  
The CPWM tim ing period (TPWM) is determ ined by the  
following equation:  
SPD - Speed Control Input  
The voltage applied to the SPD pin provides control  
over the Fan Motor speed by varying the Pulse Width  
Modulated (PWM) drive ratio at the Ph1Lo and Ph2Lo  
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.  
IPWMC and IPWMD are the charge and  
discharge currents in ␮A.

FG - Frequency Generator (speed) output  
This is the Frequency Generator output and is a  
buffered signal from the Hall sensor.  
As these threshold voltages are nom inally set to VTHH

CLCK - Locked rotor tim ing capacitor  
Ph1Lo & Ph2Lo - Driver  
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 predeterm ined tim e (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 attem pt  
to re-start the fan. This cycle of (TOFF) and (TON) will be  
repeated indefinitely or until the fan re-starts.  
This pair of outputs drive the external devices. These  
outputs provide both the com m utation and PWM  
waveform s. The outputs are of the Darlington em itter  
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 80m A 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 16m A when driving low to aid turn off  
tim es during PWM operation. When the Phase is  
inactive the output is held low by an internal pull-down  
resistor.  
GND - Ground  
This is the device supply ground return pin and will  
generally be the m ost negative supply pin to the fan.  
V+OP - Phase Outputs Supply Voltage  
RD - Locked Rotor error output  
This pin is the supply to the Phase outputs and will be  
co n n e cte d d iffe re n tly d e p e n d a n t u p o n e xte rn a l  
transistor type.  
This pin is the Locked Rotor output as referred to in the  
C
LCK tim ing section above. It is high when the rotor is  
stopped and low when it is running.  
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.  
This is an open collector drive giving an active pull  
down with the high level being provided by an external  
pull up resistor.  
For MOSFET devices the pin will connect directly to the  
VCC pin.

VCC - Applied 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 m axim um rating for the device this will be  
supplied from an external regulator such as a Zener  
diode.

Applications Inform ation  
The ZXBM2004 is prim arily controlled by a voltage on A com m on form of control of fans is by a PWM signal  
the SPD pin. A voltage of 1V represents a 100% PWM at derived from a central processor or controller. This

on the SPD pin conversely represents 0% PWM. The adjusted as neccesary to com pensate for m otor none

of external com ponents.
