MLX83203KLW-DBA-000-SP

Overview

The MLX83203KLW-DBA-000-SP is an automotive-grade, high-power three-phase BLDC pre-driver IC designed for driving six external N-FETs. It integrates current sensing amplifiers and supports a wide supply voltage range of 4.5V to 28V with 45V load dump capability. The device features a 1A gate drive strength, optional charge pump for low-voltage operation, and EEPROM-based configuration. It operates up to 150°C and includes comprehensive protection against overvoltage, undervoltage, and overheating.

Feature Summary

Integrates programmable gain current sensing amplifiers for precise torque control
Supports 100% PWM operation via trickle charge pump and bootstrap circuit
Provides diagnostic feedback through serial ICOM interface indicating error characteristics
Configurable via internal EEPROM to optimize dead time and hardware protection settings

Applications

Automotive three-phase brushless DC motor drives
High-power electric vehicle subsystems requiring robust gate driving
Systems utilizing external N-FETs for power stage implementation

Procurement Notes

Verify the Not Recommended for New Designs (NRND) lifecycle status before integration into new products. Confirm package compatibility with QFN-32 footprints. Ensure design accounts for the specific EEPROM configuration requirements as pin count is minimized through internal memory settings rather than external connections.

Selection Notes

Select this component when designing automotive BLDC systems requiring integrated current sensing and high-side driver capabilities. It is suitable for applications needing wide input voltage tolerance and thermal resilience up to 150°C. Consider the NRND status if long-term production availability is critical for the project timeline.

Part Context

This part belongs to the MLX83203 series from Melexis, specifically engineered for automotive pre-driver applications. It serves as a bridge between microcontrollers and power FETs, simplifying the design of complex motor control architectures by integrating essential monitoring and protection functions within a compact QFN-32 package.
