MLX81340 LLW-BMT-003-RE Image

The MLX81340 LLW-BMT-003-RE from Melexis is a Motor Pre-Driver that has been designed for external NFETs with a total charge of up to 60 nC. It requires an input voltage of up to 36 V and provides an output current of less than 15 mA. This motor driver includes three pre-drivers suitable for both DC and BLDC motors, making it ideal for motors operating up to 500 W. It features a typical charge current and a discharge current that ensures efficient operation. The driver incorporates a built-in charge pump for driving the top N-Channel FETs to provide a reliable operation. It includes VDS protection for all N-Channel FETs that helps safeguard the system against over-voltage conditions and enhances overall safety. It is available in a surface-mount package that measures 4.10 x 4.10 mm and is ideal for 3-Phase BLDC motor drive, HVAC (blower fan), power window lifter, pumps, seat positioning, sunroof module, and valves applications.
