ET8215Q1
- Description
- ET8215Q1 is an IC with built-in three
phase MOSFET designed for BLDC motor
drive system. Due to a high level of integration,
few peripheral components are required. The
chip features 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 optional for motor
speed regulation. Moreover, the chip integrates
speed indicator, which reads motor speed in
real time via FG pin or I2C interface. Speed
control mode, current control mode or voltage
loop control mode is optional. In addition, the
chip is secured with a wide range of protection
mechanisms, including over-current protection
(OCP), under-voltage lockout (UVLO),
temperature sensor detect (TSD), motor lock
protection (MLP) and phase loss protection.
Sleep current of the chip is about 40μA.
