PT5671 PCT普诚 三相MOSFET栅极驱动器
DESCRIPTION
The PT5671 is a three-phase controller for use with N-channel external power MOSFETs and. One logiclevel input is provided for each of the six powerMOSFETs in the 3-phase bridge, allowing motors tobe driven with any commutation scheme defined byan external controller. The power MOSFETs areprotected from cross-conduction by integratedcrossover control.
PT5671 uses a new multi-power BCD technology,only requiring a single power supply of VM=4.5-32Vand a few external components.
FEATURES
● It is low consumption by BCD process adoption
● Driver up to 3-phase half-bridge gates
● Wide power-supply voltage range: Motor (VM): 4.5V - 32V
● Operating temperature range: -40 to +85°C
● Charge-pump
● Built-in protection circuits
Shoot-through protection
Under Voltage Lock Out (UVLO)
Thermal Shut Down (TSD)
APPLICATIONS
● 3-phase Sensor-L ess /hall-sensor controlled BLDC fan motor driver
● 3-phase BLDC motor
