MLX83203KLW-DDA-000-SP

Overview

The MLX83203KLW-DDA-000-SP is a high-power automotive three-phase pre-driver IC designed for brushless DC (BLDC) motors. It integrates current sensing amplifiers and operates with external N-FETs to drive motor phases. The device supports a wide supply voltage range of 4.5V to 28V, accommodating load dump conditions up to 45V. It features a QFN-32 package and includes programmable gain and dead-time settings via internal EEPROM.

Feature Summary

Integrates high-bandwidth current sensing amplifiers for precise torque control
Supports 100% PWM operation through optimized bootstrap voltage regulation
Provides comprehensive fault detection including overvoltage, undervoltage, and thermal protection
Features serial diagnostic interface for microcontroller communication

Applications

Automotive BLDC motor drives
High-power fan and pump applications
Three-phase motor control systems

Procurement Notes

Verify the specific suffix DDA against official Melexis documentation to confirm pinout and configuration differences from other variants like DCA. Ensure design-in compliance with AEC-Q100 standards. Check for end-of-life status or recommended replacement parts if applicable.

Selection Notes

Select this component when driving high-power BLDC motors requiring integrated current sensing and robust fault protection. It is suitable for applications needing compatibility with 3V and 5V microcontrollers and operation in harsh automotive environments.

Part Context

This part belongs to the MLX83203 series of pre-drivers. It complements Melexis' portfolio of embedded MCU controllers like the MLX8120x series for sensorless applications. It serves as a bridge between low-voltage logic and high-voltage power stages.

Replacement Considerations

Consult official substitution lists for equivalent pre-drivers. Verify functional compatibility regarding gate drive strength and current sensing accuracy before replacing.
