ET8061T

Description: ET8061 is an IC with built-in pre-driver
designed for three-phase BLDC motor driver
applications. Due to a high level of integration,
few peripheral components are required. The chip
supports sensored SVPWM (ET8061L) and
sensorless FOC to reduce audible noise and
minimize torque ripple in motor drives. Motor
parameters, startup control parameters and speed
regulation mode can be configured via GUI, and
are stored in built-in EEPROM. Analog voltage
input, PWM or I2C interface is available for motor
speed regulation. Moreover, the chip integrates
speed indicator to read motor speed in real time
via FG/RD_SDA pin or I2C interface. It is secured
with a wide range of protection features,
including over-current protection (OCP), current
limiting protection (CLP), under-voltage lockout
(UVLO), temperature sensor detect (TSD), motor
lock protection (MLP), configurable maximum
speed protection, bus voltage protection,
abnormal Hall input detection (HALLERR)
protection (ET8061L), etc. The chip also supports
power closed-loop control.
