Product description
The MLX80302 is a 3-phase motor controller with integrated power FETs. The device is optimized for driving small brushless DC motors with RMS current up to 1.8 A and start-up current up to 2.6 A. Both 12 V and 24 V supply voltage are supported, for applications up to 40 W.
The MLX80302 can provide electrical rotation speed (FG: Frequency Generation) or diagnostics feedback, or a combination of both. The PWM input allows speed control. Alternatively, the device can be used as a stand-alone solution and run the motor at full speed. The MLX80302 can be configured for fast rotor-alignment, allowing reaching maximum motor speed within 50 ms.
The operating voltage ranges from 6.0 V up to 28 V.
The integrated current limit prevents excessive peak currents during rotor alignment, motor start-up and high-load operating conditions. The gate drivers are optimized for low EMC.
The MLX80302 is available in an 8-pin SOIC package with exposed pad. The device has been designed and qualified to support permanent operation at a junction temperature TJ in the range of -40 °C to 150 °C.
The MLX80302 provides an I²C interface for end-of-line programming (of the EEPROM) and for motor control.
Plug-and-play application boards and evaluation boards for configuring the IC via I²C using a graphical interface, are available now.
