BLDC Motor Control Kit with ATA6833/ATA6834
The following MCU peripherals are used:
• PSC - Power Stage Controller
• 8-bit Timer/Counter 0
• 16-bit Timer/Counter 1
• 10-bit ADC
• 64 MHz PLL
• Analog Comparators
• LIN/UART interface
– All 6 PSC output channels are used for controlling the half-bridges
– 64 MHz input clock
– 10-bit bandwidth and the center-aligned mode of the PWM signal result in a
– This timer is used to generate different time bases (e.g. 250 µs, 20 ms, 200 ms
– This timer is used to measure the rotation speed and to detect time out when the
– ADC channel 6 gives the X position of the touch event
– ADC channel 5 gives the Y position of the touch event
– 16 MHz as input clock for CPU
– 64 MHz as input clock for PSC
– Analog Comparator AC1, AC2 and AC3 are used for Hall sensors edge detection
– Configured as LIN 1.3 slave, baud rate 19200
switching frequency of 31.280 kHz
