Brushless DC Motor Driver Module in a Power Flatpack
600V, 20 Amp
FEATURES:
• Fully integrated 3-Phase Brushless DC Motor Control Subsystem
includes power stage, non-isolated driver stage, and controller stage
• IGBT Output Stage
• 20A Average DC bus current with 600V Maximum Peak Bus Voltage
• Internal Precision Current Sense Resistor (10W max. dissipation)
• Speed and Direction Control of Motor
• Brake Input for Dynamic Braking of Motor
• Over-voltage/Coast Input for Shutdown of All Power Switches
• Soft Start for Safe Motor Starting
• Hermetic (3.10" x 2.10" x 0.385")
APPLICATIONS:
• Fans and Pumps
• Hoists
• Actuator Systems
DESCRIPTION:
The SMC6G20-60 is an, integrated three-phase brushless DC motor controller/driver subsystems housed
in a 43 pin power flatpack. The SMC6G20-60 is best used as a two-quadrant speed controller for
controlling/driving fans, pumps, and motors in applications that require small size. Many integral control
features provide the user much flexibility in adapting the SMC6G20-60 to specific system requirements.
The small size of the complete subsystem is ideal for aerospace, military, and high-end industrial
applications.

COMMUTATION TRUTH TABLE
This table shows the Phase Output state versus the state of the Hall-Effect and Direction Inputs. Please note that the
SMC6G20-60 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 Hall-Effect sensors that are spaced at 120o 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).
