MCF8315C
Overview
- Three-phase BLDC motor driver with integrated sensorless motor control algorithm - Code-free Field Oriented Control (FOC) - Offline motor parameters measurement with Motor Parameter Extraction Tool (MPET) - 5-point configurable speed profile support - Windmilling support through forward resynchronization and reverse drive - Analog, PWM, freq. or I2C based speed input - Configurable motor start-up and stop options - Anti-voltage surge (AVS) protection - Improved acoustic performance with automatic dead time compensation - Variable monitoring through DACOUT pin
- 4.5 to 35V operating voltage (40V abs max)
- High (peak) output current capability: 4A (RRY), 3.5A (PWP)
- Low MOSFET on-state resistance - RRY: RDS(ON)(H+L) at TJ=25°C: 250mΩ(typ.) - PWP: RDS(ON)(H+L) at TJ=25°C: 265mΩ(typ.)
- Low power sleep mode: Refer Table 6-7 - 5µA (maximum) at VVM = 24V, TA = 25°C
- Speed loop accuracy: 3% with internal clock and 1% with external clock reference
- Customer-configurable non-volatile memory (EEPROM) to store device configuration
- Supports up to 60-kHz PWM frequency for low inductance motor support
- Does not require external current sense resistors; uses built-in current sensing
- Built-in 3.3V, 20mA LDO regulator
