ET8132S

Description: ET8132 is an IC with built-in three-phase predriver designed for BLDC motor drive system. 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, current-loop, power-loop or voltage-loop
control mode is optional. In addition, the chip is
secured with various 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 current of the chip is about 60μA.
