Melexis MLX83100 Automotive 2-Phase DC Pre-Drivers are with an integrated current sense amplifier. The MLX83100 pre-drivers are used to drive brushed DC motors in combination with a microcontroller and four discrete power N-FETs. These drivers control four external N-FETs for full H-bridge control in the supply range from 4.5V to 28V. MLX83100 pre-drivers include various monitoring and protection functions and gate-source voltage monitoring of the external N-FETs. The MLX83100 provides an EEPROM for configure-ability, avoiding the need for a high pin-count package. Applications include Water pump, fuel pump, engine cooling fan, wiper, sunroof, blowers, and compressors.
