PT5671
DESCRIPTION
The PT5671 is a three-phase controller for use with N-channel external power MOSFETs and. One logic level input is provided for each of the six power MOSFETs in the 3-phase bridge, allowing motors to be driven with any mutation scheme defined by an external controller. The power MOSFETs are protected from cross-conduction by integrated crossover control.
PT5671 uses a new multi-power BCD technology, only requiring a single power supply of VM = 4.5
- 32V and a few external ponents.
