VARIABLE SPEED 2-PHASE FAN MOTOR CONTROLLER
DESCRIPTION
The ZXBM200x is a series of 2-phase, DC brushless motor pre-drivers with PWM
variable speed control suitable for fan and blower motors.
FEATURES
Built in lock detect protection, rotational speed sensing and automatic recovery
·
Built in Hall amplifier allows direct connection to Hall element
·
PWM Speed control can be implemented via external voltage or resistance (thermistor) input
·
Speed (FG) pulse output – ZXBM2003
·
Rotor lock output – ZXBM2002
·
· Combined Rotor Lock (RD) and Speed (FG) signal – ZXBM2001
· Up to 18V input voltage (60V with external regulator)
· MSOP10 package

Notes:
1
Measured with pins H+, H-, C
2
The 1V minimum represents 100% PWM drive and 2V represents 0% PWM drive.
3
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 ⫾20% manufacturing tolerance.
