DATA SHEET www.onsemi.com Sensorless BLDC ecoSpin Motor Controller, with Gate Drivers Arm Cortex M0+, 600 V, FAN73896 Product Preview ECS640A Overview WQFN65 EcoSpin Motor Controller ECS640A is a 3 phase BLDC CASE 510CT configurable motor control system in package that integrates an ultra low power optimized Arm Cortex M0+ microcontroller MARKING DIAGRAM (Nebo4064), three sense amplifiers and a reference amplifier (NCS20034), three bootstrap diodes, and a highvoltage gatedriver designed for highvoltage, highspeed operation, with the ability to XXXXXXXX drive MOSFETs and IGBTs operating up to 600 V (FAN73896). Six AWLYWW 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 lowside source pins allow for single or multiple shunt XXXXXXXX = Specific Device Code measurement. A = Assembly Location Protection functions include undervoltage lockout and inverter WL = Wafer Lot Y = Year over current trip with an automatic fault clear function. An WW = Work Week opendrain fault signal is provided to indicate that a fault condition = Logo(s) has occurred. Direct Torque & Flux Control (DTFC) firmware is available and allows optimal motor performance on the Arm CortexM0+ platform. ORDERING INFORMATION The small footprint and integration make this device a perfect fit See detailed ordering and shipping information on page 12 of this data sheet. with discrete power devices to maximize scalability across platforms and to minimize area requirements as power levels scale.
