onsemi ECS640A
ECS640A is a 3−phase BLDC configurable motor control system in package that integrates an ultra−low−power optimized Arm Cortex−M0+ microcontroller (Nebo−40−64), 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 600 V (FAN73896). The device includes Hall Sensor inputs to support either sensored or sensorless operation.| Part No. | ECS640A |
