Outline
The M63155FP is a three phase brushless motor controller with six external N-channel Power MOSFETs. The motor
coil current is controlled by either a PWM pulse duty or a D/A signal level from an external controller.
Both VCC1 and VCC2 can be supplied by either external power supply or internal 5V regulator. Also voltage monitor
is available, and whichever of power supplies drops down, it generates an error signal.
Either fast or slow current-decay, either coast(free-run) or dynamic brake(short-brake) can be selected. Several
protection circuits are built in, thermal shut down and so on.
Internal tachometer, direction control and oscillator for internal logic are also available.
Features
• Wide voltage range: From 10V to 40V (VM)
• 5V regulator with the external PNP transistor
• Internal gate supply voltage generator (Charge pump)
• Voltage monitor
(VM , SVCC , External FET gate & External FET drain-source)
(Voltage monitor of External FET gate & External drain-source can be disabled.)
• Motor current control by either a PWM duty or a D/A level
• Selectable fast or slow current-decay
• Selectable coast (free-run) or dynamic brake (short-brake)
• FG internal tachometer (3phase mixed)
• Direction control
• Thermal Shut Down (TSD)
• Power loss brake
• Protection for invalid hall codes
Application
• High Power Three Phase Brushless Motor.
