Melexis has announced the launch of a powerful and cost-effective new motorcycle fuel pump controller, the MLX 80302, to help manufacturers comply with increasingly stringent environmental regulations, including the Indian BS-6 emissions standard.
The MLX 80302 is a three-phase BLDC brushless DC motor controller IC with 2.6A peak drive capability. The product is suitable for automotive and motorcycle pump applications with a battery voltage of 13 V and power up to 20 W. In addition, it is ideal for a wide range of home appliance and industrial pump applications with 24 V regulated power supplies up to 30 W.
The controller has a wide junction temperature range: -40°C to +150°C. With a 0.25 ohm half-bridge on-resistance driver, the MLX 80302 offers a powerful monolithic pump controller in a SOIC8 package. The product requires only reverse polarity protection and a decoupling capacitor, making it ideal for integration into pump connectors.
The MLX 80302 features a variety of integrated protection features, including locking rotor, overheat protection, overvoltage protection, short circuit protection and current limiting. Motor control operations are proven to perform robust operation in very noisy environments with remote motor positioning and have passed a range of tests including BCI as well as ignition coil noise injection. The MLX 80302 is fast to start (up to 50 ms) and is very stable and reliable under load and no load conditions.
The MLX 80302 can be programmed using a graphical interface GUI via an I2C interface, and all options can be configured via on-chip EEPROM. With multiple PWM input options to choose from, the product can configure the motor start process to reach the maximum target speed of the fuel pump in less than 60 ms, even under pressure. The MLX 80302 is packaged in SOIC8 exposed pad.
