Description
The ZXBM2004 is a 2-phase, Brushless Direct Current (BLDC) motor control pre-driver with variable PWM speed control suitable for fan and blower motors.
For system flexibility, motor speed can be controlled by changing SPD pin voltage which can be either from Thermistor network, external voltage or PWM signal.
To help protect the motor coil, the ZXBM2004 provides Rotor Lock Protection which shuts down the output drive if rotor lock is detected. The device automatically re-starts when the rotor lock is removed.
NEW PRODUCT
A Tachometer output is provided by open-drain Frequency Generator (FG) Pin which allows external interface to monitor motor rotation or speed. The FG output is the magnetic change frequency.
The ZXBM2004 is available in small space saving low prof ile U-QFN3030-16 and QSOP-16 packages.

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 t ype. For a 4 pin dev ice the di fferential Ha ll output signal is co nnec ted 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 V H-, Ph2 is the active drive.
ThRef - Output Reference Voltage
This is a reference voltage of nominal 3V. It is designed for the abil ity to 'source' and therefore it will not 'sink' any current from a higher voltage. The current drawn from the pin by the minim um speed potential divider to pin S
setting network should not exceed 1mA in total at maximum temperature.
NEW PRODUCT
SPD - Speed Control Input
The voltage applied to the SPD pin provides control over motor spee d 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 sp eed 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.
S
– Minimum Speed Setting
MIN
A voltage can be set on S pin such that internally SPD voltage cannot rise above S
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.
C
– Output PWM Frequency Setting
PWM
This pin has an external capacitor attached to set the PWM frequency for the Phase drive outputs. A cap acitor value of 0.1nF will provide a PWM frequency of typically 24kHz. The C

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 provi ded 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 tra nsistors as shown in the Typical Application circuit following.
When in the low state the active Phase drive is capable of sinking u p to 16mA when driving low to aid turn off times during

ZXBM2004
Application Note
The ZXBM2004 is primarily controlled by a voltage o n the SPD pin. A voltage of 1V represents a 100% PWM at the P hase Outputs and in turn represents full speed. 3V on the SPD pin conversely repres ents 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 necessar y to compensate for motor none linearity, inclusion of the Minimum speed feature etc.
Full applications details and further examples of ho w to control the ZXBM2004 are av ailable in the App lications Notes AN41, AN42 and AN43.
