MLX83100 Automotive 2-Phase DC Pre-Driver Datasheet

PublishTime：2020-07-24

The MLX83100 is a two phase pre-driver (also called ‘bridge’ or ‘gate’ driver) IC with integrated current sense amplifier. This device is used to drive brushed DC motors in combination with a microcontroller and four discrete power N-FETs.
The device is able to control four external N-FETs for full H-bridge control in the supply range from 4.5V to 28V, by means of the integrated charge pump. The high side gate drivers are supplied via bootstrap circuits. The bootstrap voltage regulator is optimized for gate charges up to 500nC per FET at 20 kHz PWM.
The device comprises various monitoring and protection functions, including under voltage and over voltage detection at multiple internal voltage nodes, over temperature detection, drain-source and gate-source voltage monitoring of the external N-FETs. In case of fault detection, the ICOM diagnostics interface will inform the microcontroller with a PWM signal, where the duty cycle indicates the nature of the error.
An integrated fast, high-bandwidth, low offset current sense amplifier allows for precise torque control, with programmable gain selection.
The MLX83100 provides an EEPROM for configurability, avoiding the need for a high pin-count package. The configuration allows the customer to optimize the pre-driver’s operation for different applications.
