Description
BD8379FV-ME2 is a ROHM motor-driver IC designed to drive small motors from a microcontroller. It provides programmable current regulation with a PWM drive interface and includes built-in protections (overcurrent/short-circuit, undervoltage, overtemperature) in a compact ME2 package. Typical applications include printers, robotics, and consumer/automotive actuators where simple, safe motor control is needed. For exact pinout and electrical specs, refer to the ROHM datasheet; the ME2 suffix indicates a specific package/variant.
Features
Key features of BD8379FV-ME2 (concise):
- 3-phase brushless DC motor driver with integrated half-bridge FETs
- Sensorless 6-step commutation using back-EMF
- PWM speed control input with built-in current regulation
- Adjustable current limit with current-sense feedback
- Protections: overcurrent, overvoltage, undervoltage, and overtemperature/thermal shutdown
- Fault reporting with diagnostic output (fault latch)
- Enable, Brake, and Sleep control pins
- Soft-start and controlled decay for low EMI during startup/shutdown
- Compact ME2 package
Note: For exact electrical specs (voltage range, current limits, pinout), refer to the official datasheet.
