The ZXBM1016 is a high efficiency, low noise,
single-phase, DC brushless motor pre-driver
with PWM variable speed control and current
control suitable for fan and blower motors.
High efficiency and low noise are achieved
using a novel technique (patent pending) for
commutation current control. The controllers are primarily intended to meet
industry standard OEM fan specifications where
external PWM control are applied, however,
they can also be used with other thermal control
techniques using an external voltage, PWM
signal or thermistor.
Features
• Compliant with external PWM speed control
• Compliant with thermistor control
• Minimum speed setting
• High efficiency utilizing tail-end current control
• Low noise
• Auto restart
• Built in Hall amplifier
• Hall bias
• Speed pulse (FG) output
• Integrated current control
• Up to 18V input voltage (60V with external regulator)
• Small TSSOP20 package
Applications
• Mainframe and personal computer fans and
blowers
• Instrumentation fans
• Central heating blowers
• Automotive climate control
