NFMECS640A0

ECS640A is an ecoSpin™ BLDC motor controller +MCU. The newest member of the ecoSpin™ family of configurable motor controllers, is a 3−phase BLDC motor controller that integrates a ultra-low-power optimized arm Cortex-M0+ microcontroller, three sense amplifiers and a reference amplifier (NCS20034), three bootstrap diodes, and a high-voltage gate−driver designed for high-voltage, high-speed operation, with the ability to drive MOSFETs and IGBTs operating up to 600V (FAN73896). Six gate driver outputs provide sink/source of 350mA/650mA (typ) gate current to external power devices. Protection functions include under-voltage lockout and inverter over-current trip with an automatic fault-clear function. Applications are refrigeration compressors and blowers, HVAC blowers and condensers, pool pumps, industrial drives and pumps, robotics, refrigerators, bottle coolers, consumer A/C units, HVAC blowers, commercial A/C units.

• Three independent low−side source pins allow for single or multiple shunt measurement
• Under-voltage lockout/inverter over-current trip with an automatic fault-clear function protection
• Arm cortex M0+ embedded uC with 64kB flash memory and 8kB SRAM
• 600V FAN73896 gate-driver, small footprint SiP, improved reliability in a qualified, tested solution
• Easy to use user environment, shorter TTM, ease of adoption, and advanced control algorithms
• Proven gate-driver with protection features enables off-line operation in HV applications
• Enables single or three-shunt operation in a compact footprint, GAQFN65 13x10, 0.5P package
• Enables ease of embedding, simplified PCB layout and scalability over multiple power levels
• Simplifies code development and debugging, leading to shorter development spans
• Includes hall sensor inputs to support either sensored or sensorless operation
