ECS640A

Overview

EcoSpin 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 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.

MARKING DIAGRAM

XXXXXXXX

AWLYWW

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.
