EU6862L
- Description
- The high-performance motor drive chip incorporates ME core and 8051 core. ME core integrates FOC,
MDU, LPF, PID and SVPWM modules that allow for automatic calculation of FOC or square-wave control
by the hardware for sensored/sensorless BLDC/PMSM motors. 8051 core is used for parameter configuration
and routine processing. Most of 8051 core instruction cycle takes 1T or 2T clock cycle(s). The dual cores
work in parallel to achieve high-performance motor control. The chip integrates high-speed operational
amplifiers, comparators, pre-driver, high-speed ADC, multiplier/divider, CRC, SPI, I2C, UART, Timers,
PWM module and high-voltage LDO, which are suitable for FOC or square-wave based BLDC/PMSM
motors.
See section Driver for the differences among EU6812, EU6861 and EU6862. EU6812 supports PWM
output and EU6861/EU6862 supports 6N pre-driver output.
EU6812 includes EU6812L2(LQFP48), EU6812N2(QFN32), EU6812S2(SSOP24) and
EU6812V(SSOP24).
EU6861 includes EU6861Q2(QFN56), EU6861N2/EU6861NF2(QFN40) and EU6861L2(LQFP48).
EU6862 includes EU6862L(LQFP48) and EU6862Q(QFN48_38).
For concise description and easy differentiation, if it is specified that a feature is applied to a specific
model, the feature is exclusive to this model. Otherwise, the feature is a common feature of the product family.
