ECS640A数据手册ONSEMI中文资料规格书

描述 Description

The newest member of the ecoSpinTM family of configurable motor controllers, onsemi part #ECS640A, 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 350 mA/650 mA (typ) gate current to external power devices. The device includes Hall Sensor inputs to support either sensored or sensorless operation. Three independent low−side source pins allow for single or multiple shunt measurement.
Protection functions include under-voltage lockout and inverter over-current trip with an automatic fault-clear function. An open-drain fault signal is provided to indicate that a fault condition has occurred.
Direct Torque & Flux Control (DTFC) firmware is available and allows optimal motor performance on the Arm Cortex-M0+ platform.  Customer directly licenses DTFC code from Theta Power Systems, Intl. Please contact onsemi Sales for more information.
The small footprint and integration make this device a perfect fit with discrete power devices to maximize scalability across platforms and to minimize area requirements as power levels scale.
