Introduction

The MLX83203-2 is a three phase pre-driver (also called ‘bridge’ or ‘gate’ driver) IC with integrated current sense amplifier. This device is used to drive brushless DC motors in combination with a microcontroller and six discrete power N-FETs. For the high power applications, the MLX83203 provides powerful gate drivers of 1A typical. The MLX83202 has reduced gate drive strength of 300mA and targets mid power applications. Both devices are able to control six external N-FETs 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 trickle charge pump allows 100% PWM operation despite the use of bootstrap capacitors. The bootstrap voltage regulator is optimized for gate charges up to 350nC 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, whose 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 MLX83203-2 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.
