Melexis has expanded its MLX90412 product offering with a new MLX90412GLW single-coil pump/fan IC which is optimized to operate at high junction temperatures up to 160°C and is qualified to meet operating lifetime demand up to 15,000 hours. This new IC with integrated driver stage drives 15W pumps up to 135°C in ICEs and 20W pumps up to 85C in EVs. This IC offers the lowest noise performance ideal for EVs over a high torque mode. Moreover, it offers low EMI mode, for ON/OFF applications requiring minimum external EMI filter components. Air pump, water pump, axial fans, radial blower, and cross blower are some applications for the IC.
The MLX90412GLW includes an all-in-one fan driver, including a motor controller, hall sensor, and 0.35 Ohm driver. Along with 2.2 A motor current, adaptive commutation, PWM control input, and Operating supply range from 3.5 V to 32 V. The device can operate basic two-wire pumps with ON/OFF functionality and features short circuit protection, fast prototyping. The IC is available in the market.
