Frequently Asked Questions
How many PWM channels does ST7MC2S6T6 provide for 3-phase brushless motor control?
ST7MC2S6T6 provides 6 complementary PWM output channels organized as 3 high-side and 3 low-side signals, covering a complete 3-phase inverter bridge. The PWM resolution supports frequencies up to 16 MHz clock base, and programmable deadtime insertion prevents shoot-through in MOSFET gate drive circuits.
What ADC resolution and channel count does ST7MC2S6T6 offer for motor current sensing?
The integrated ADC provides 10-bit resolution across up to 8 input channels, suitable for phase current measurement, DC bus voltage monitoring, and NTC temperature sensing in brushless motor drives. Conversion time is compatible with 16 MHz CPU operation, allowing real-time closed-loop current control.
Is ST7MC2S6T6 a lower-cost alternative to 32-bit MCUs for simple 3-phase BLDC fan controllers?
Yes, ST7MC2S6T6 targets cost-sensitive BLDC applications like HVAC fans and pumps where a 32-bit MCU would be over-specified. Its 8-bit architecture, 44-pin QFP package, and on-chip motor control peripherals reduce BOM cost versus adding discrete gate drivers or a larger Cortex-M device.
What communication interfaces are available on ST7MC2S6T6 for system-level connectivity?
ST7MC2S6T6 integrates one SPI port and one LIN/SCI (UART-compatible) serial interface, supporting 26 general-purpose I/O lines. The LIN interface enables low-cost single-wire communication at up to 20 kbps for automotive or appliance control networks without additional protocol ICs.
