Smart LIN pre-driver IC for DC, stepper, BLDC motors (>1A motor current) - MLX81325
Product description
The MLX81325 is part of the our smart LIN motor driver IC family. The MLX81325 enables small-footprint applications to control small BLDC, stepper and DC motors with compact external NFETS to drive the motor sensored or sensorless with low noise, and a digital LIN interface for commands and feedback.
The LIN interface is compliant with LIN 1, LIN 2, J2602, and can be configured for PWM communication.
Typical applications:
- Small DC and BLDC pumps or valves
- DC motor positioning for window lift, sunroofs, seats, doors with LIN
- DC blowers or DC fans with LIN
