Overview
The MLX83203KLW-DDA-000-RE is a three-phase BLDC pre-driver IC designed for automotive applications. It operates within a supply voltage range of 4.5V to 28V and supports load dump up to 45V. The device provides a gate drive strength of 1A, suitable for high-power applications. It features an integrated current sense amplifier with programmable gain ranging from 8 to 48 and dead time adjustment between 0 and 6μs. The component functions in temperatures from -40°C to 125°C and utilizes a 32-pin QFN package measuring 5x5mm.
Feature Summary
- Integrates a current sense amplifier with programmable gain for precise torque control
- Supports 100% PWM operation via trickle charge pump and bootstrap circuit
- Includes comprehensive protection against overvoltage, undervoltage, and overheating
- Features EEPROM configuration for customizable dead time and hardware protection settings
Applications
- Automotive three-phase brushless DC motor drives
- High-power motor control systems requiring external N-FETs
- Applications demanding precise current sensing and torque regulation
Procurement Notes
Verify the specific suffix RE indicates reel packaging when ordering. Confirm the DDA variant matches the required pinout and configuration options. Ensure compatibility with 3V or 5V microcontroller interfaces. Check that the 32-QFN EP package fits the thermal and spatial constraints of the target design. Validate RoHS compliance status for the specific batch if required by regulatory standards.
Selection Notes
Select this component for designs requiring a dedicated pre-driver rather than an integrated controller. It is appropriate when external power MOSFETs are preferred for higher current handling. Consider the integrated current sense amplifier if board space for discrete amplifiers is limited. The EEPROM configuration allows optimization for specific motor characteristics without changing hardware. Ensure the application benefits from the wide operating temperature range.
Part Context
This part belongs to the MLX83203 series of automotive-grade pre-drivers. It complements the MLX83100 for DC applications and the MLX8120x series for sensorless BLDC control. The device simplifies the interface between microcontrollers and power stages by handling gate driving and fault detection logic.
Replacement Considerations
MLX83203KLW-DDA-000-SP is available as an alternative packaging option (tape and reel vs. tray/reel variations depending on distributor definitions). Verify pin compatibility before substitution. No direct cross-brand replacements are confirmed in public documentation.
