ECS640A Datasheet | onsemi

Overview Eco Spin Motor Controller 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). Six gate driver outputs provide sink/source of 350 m A/650 m A (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. 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.
