ET8133Q

Description: ET8133Q is an IC with built-in pre-driver for
three-phase BLDC motor driver applications. Due to a
high level of integration, the chip has few peripheral
components and is featured with low noise and small
torque ripple. Motor parameters, startup control
parameters and speed regulation mode can be
configured via GUI, and are stored in built-in
EEPROM. Analog voltage, PWM, I2C interface or
CLOCK mode is available for motor speed regulation.
Moreover, the chip integrates speed indicator to read
motor speed in real time via FG pin or I2C interface.
Speed-loop control mode, current-loop control mode
or voltage-loop control mode is optional. In addition,
the chip is secured with a wide range of protection
features, including over-current protection (OCP),
under-voltage lockout (UVLO), over-voltage lockout
(OVLO), motor lock protection (MLP), phase loss
protection, abnormal Hall input detection (HALLERR)
protection, etc. Sleep-mode current of the chip is about
60μA.
