STK984-091A-E: Motor Driver, DC, 3-Phase, Brushless

Product Description
The STK984-091A-E is a 3-phase BLDC motor driver hybrid IC cosisted of pre-driver and power MOSFET. It has shunt resistor and thermistor built in. So, various protective functions against over-temperature, over-current, over-voltage and low voltage are incorporated. You can design BLDC motor drive circuit easily and reduce the PCB area.
Features   Benefits
     
  • Built-in pre-driver IC
 
  • FET can be driven by microcontroller output ( logic system)
  • Various protections (Overcurrent Protection, Over Temperature Protection, Low Voltage Protection, Over Voltage Protection) are incorporated
 
  • Protected by various abnormal states
  • On board terminals that output fault signal on board a reset terminal
 
  • Easy to confirm which protection function acted. (Over current or Over temperature)
  • Built-in shunt resistor
 
  • The current detection is possible
  • Dual-Stage Charge-pump for low voltage operation (Cranking)

 
  • External boot strap diodes and condensers are unnecessary
