Sensorless Motor Driver 1.8V/3.3V 64-Pin PQFP T/R

High Performance Appliance Motion Control IC integrating the Motion Control Engine (MCE) with a Microcontroller.

• MCE™ (Motion Control Engine) - Hardware based computation engine for high efficiency sinusoidal sensorless control of permanent magnet AC motor
• Supports both interior and surface permanent magnet motors
• Built-in hardware peripheral for single shunt current feedback reconstruction
• No external current or voltage sensing operational amplifier required
• Three/two-phase Space Vector PWM
• Three-channel analog output (PWM)
• Embedded 8-bit high speed microcontroller (8051) for flexible I/O and man-machine control
• JTAG programming port for emulation/debugger
• Serial communication interface (UART)
• I2C/SPI serial interface
• Watchdog timer with independent analog clock
• Three general purpose timers/counters
• Two special timers: periodic timer, capture timer
• Internal ‘One-Time Programmable’ (OTP) memory and internal RAM for final production usage
• Pin compatible with IRMCF341, RAM version
• 1.8V/3.3V CMOS
