Overview
The MCF8316A provides a single-chip codeless sensorless FOC solution for customers driving speed-controlled 12V to 24V BLDC or PMSM motors with peak currents up to 8A. The MCF8316A integrates three 1/2-H bridges with an absolute maximum voltage of 40V and ultra-low RDS(ON) of 95mΩ (high-side + low-side). Power management family with adjustable buck regulator and LDO
Applications
- Brushless DC (BLDC) motor modules
- Residential and living fans
- Air purifier and humidifier fans
- Washing machine and dishwasher pumps
- Automotive fans and blowers
- Medical CPAP blowers
Key features
- Three-phase BLDC motor driver with integrated sensorless motor control algorithm
- Code-free Field-Oriented Control (FOC)
- Offline motor parameter measurement using Motor Parameter Extraction Tool (MPET)
- 5-point configurable speed profile support
- Wind turbine support via forward resynchronization and regenerative braking
- Analog, PWM, frequency, or I2C-based speed input
- Configurable motor start and stop options
- Anti-voltage surge protection against overvoltage
- 4.5V to 35V operating voltage (absolute maximum 40V)
- High output current capability: 8A peak
- Low MOSFET on-state resistance, RDS(ON)(HS + LS) = 95mΩ at TA = 25°C
- Low-power sleep mode, 3μA (maximum) at VVm = 24V, TA = 25°C
- Speed loop accuracy: 3% with internal clock, 1% with external clock reference
- Customer-configurable non-volatile memory (EEPROM) for device configuration storage
- PWM frequency support up to 75kHz for low-inductance motors
- No external current sense resistor required; built-in current sensing
- Integrated 3.3V ±5%, 20mA LDO regulator
- Integrated 3.3V/5V, 170mA buck regulator
- Dedicated DRVOFF pin to disable (Hi-Z) outputs
- Spread spectrum and slew rate control for EMI reduction
- Power supply undervoltage lockout (UVLO)
- Motor lock detection (5 different types)
- Overcurrent protection (OCP)
- Thermal warning and thermal shutdown (OTW/TSD)
- Fault condition indicator pin (nFAULT)
- Optional fault diagnostics via I2C interface
- Capable of generating 3.3V or 5.0V rail for external circuit power supply
- Algorithm configuration storable in non-volatile EEPROM, enabling standalone operation after configuration. The device accepts speed commands via PWM input, analog voltage, variable-frequency square wave, or I2C commands. MCF8316A integrates multiple protection features designed to protect the device, motor, and system during fault events
