EU6361Q
- Description
- The high-performance motor drive chip incorporates ME core and 8051 core. ME core implements
motor control in real time and 8051 core is used for parameter configuration and routine processing. The dual
cores work in parallel to achieve high-performance motor control. The chip integrates high-speed operational
amplifiers, comparators, high-speed ADC, multiplier/divider, CRC, SPI, I2C, UART, Timers, PWM modules,
built-in high-voltage LDO, which are suitable for FOC or square-wave based BLDC/PMSM motors.
Package type of the chip: QFN56
- Features
-
◼ Power supply:
➢ Single-power supply mode: When VCC_MODE = 0, external power supply 5V~24V is connected
to VCC pin, and internal LDO supplies VDD5 voltage.
➢ Dual-power supply mode: When VCC_MODE = 1, external power supply 1 (5V~36V) is
connected to VCC pin, and external power supply 2 (5V) is connected to VDD5 pin. VCC≥VDD5.
