FULL-FEATURED POWER MODULE FOR DIRECT DRIVE OF 3-PHASE BRUSHLESS DC MOTORS 25 Amp. Push-Pull 3-Phase Brushless DC Motor Controller/Driver Module in a Power Flatpack FEATURESFully integrated 3-Phase Brushless DC Motor Control Subsystem includes power stage, non-isolated driver stage, and controller stage MOSFET Output Stage 25A Average Phase Current with 160V Maximum Bus Voltage Internal Precision Current Sense Resistor (6W max. dissipation) Speed and Direction Control of Motor Brake Input for Dynamic Braking of Motor Overvoltage/Coast Input for Shutdown of All Power Switches Soft Start for Safe Motor Starting Unique Hermetic or Plastic Ring Frame Power Flatpacks Hermetic x 0.385") Plastic Ring Frame x 0.49") APPLICATIONSDESCRIPTION The OM9375 is one of a series of versatile, integrated three-phase brushless DC motor controller/driver subsystems housed a 43 pin power flatpack. The OM9375 is best used as a two quadrant speed controller for controlling/driving fans, pumps, and motors in applications which require small size. Many integral control features provide the user much flexibility in adapting the OM9375 to specific system requirements. The small size of the complete subsystem is ideal for aerospace, military, and high-end industrial applications. Two package types provide a broad range of cost and screening options to fit any application. 205 Crawford Street, Leominster, MA 01453 USA (978) 534-5776 FAX (978) 537-4246 Visit Our Web Site at www.omnirel.com This table shows the Phase Output state versus the state of the Hall-Effect and Direction Inputs. Please note that the OM9375 Hall-Effect Inputs are Grey-encoded; that is, only one input is allowed to change from one input state to another at a time. The commutation coding shown reflects HallEffect sensors that are spaced at 120� mechanical increments. Also, internal protection logic disables all three Phase Outputs when the Hall-Effect Inputs are set to an illegal condition (i.e. all logic low or all logic high).
