ZXBM2004 Two Phase BLDC Motor Pre-driver

with Speed Control and Minimum Speed Setting

The ZXBM2004 is a two phase,

Brushless Direct Current (BLDC)

motor control pre-driver with

speed control and minimum speed

setting suitable for fans, blowers

and motors.

For system flexibility the motor

speed can be controlled by a

voltage signal from either a

Thermistor network, external

control voltage or a PWM signal.

The ZXBM2004 minimizes

electromagnetic interference

(EMI) by allowing the user to

adjust the switch-on speed of the

external power switches via a

single resistor.

To help protect the motor coils,

the ZXBM2004 provides rotor lock

protection and auto re-start.

The open-drain Frequency

Generator (FG) pin allows an

external interface to monitor motor

rotation and speed while the open-

drain Rotation Detect (Rd) pin

allows to monitor rotor status.

The ZXBM2004 is now available

in space saving low profile

U-QFN3030-16 in addition to

QSOP16 package.

The Diodes Advantage

A reliable high perform ance pre-driver with an extended feature set for a

simple and cost effective solution for two phase fans and motor control

applications

 High source and sink output drive

High source/sink capabilityof 80mA/16mAallows external Bipolar or

MOSFET switches to be scaled in power for wide range of fan and motor

applications

 Adjustable switch-on speed

With a single resistor the power switch turn-on speed can be adjusted to

help provide the optimum EMI noise performance

 PWM, DC or Thermistor speed control pin

Flexible speed control by either an external PWM signal,

variable supplyvoltage or by a resistor-thermistor network

 Lock detect, shutdown and automatic restart

Protects coils from over-heating or burning out

 Wide operating temperature range -40oC to 110oC

Suitable for thermallydemanding applications

 Small packaging

U-QFN3030-16 provides a very small low profile solution, over 3.5 times

sm aller than the QSOP16

Applications

 Cooling fans for desktops PC’s and

servers

 Fans and motors for home appliances

 Extractor fans

 Pumps and motors
