Overview
The MLX83100LGO-DDA-000-RE is an automotive-grade two-phase pre-driver IC designed for brushed DC motor applications. It integrates current sensing amplifiers and converts microcontroller PWM inputs to drive four external N-FETs. The device supports a supply voltage range of 4.5V to 28V, featuring an optional charge pump for low-voltage operation. It includes comprehensive protection mechanisms such as overvoltage, undervoltage, and thermal shutdown, ensuring robust performance in demanding automotive environments.
Feature Summary
- Integrates current sensing amplifiers for precise motor control
- Converts microcontroller PWM signals to drive four external N-FETs
- Includes optional charge pump for low power voltage operation
- Provides extensive fault detection and protection features
Applications
- Automotive brushed DC motor drives
- Window lift systems
- Seat adjustment actuators
- Sunroof mechanisms
Procurement Notes
Verify the complete part number including suffixes against official Melexis documentation to ensure correct package and tape/reel specifications. Confirm that the specific variant matches your system's voltage and interface requirements. Check for any recent revisions or obsolescence notices directly from the manufacturer before finalizing procurement plans.
Selection Notes
Select this component when driving brushed DC motors with external power FETs is required. It is suitable for applications needing integrated current sensing and robust automotive-grade reliability. Consider the MLX83203 if three-phase BLDC control is needed instead. Ensure the design accommodates the external N-FETs and associated passive components for optimal performance.
Part Context
This part belongs to the MLX83100 series of automotive pre-drivers. It is distinct from the MLX83203, which targets three-phase BLDC motors, and the MLX8120x series, which are embedded MCU controllers for sensorless BLDC applications. The MLX83100 focuses specifically on two-phase brushed DC motor control with integrated signal conditioning.
Replacement Considerations
No direct public substitute part numbers are confirmed for this specific variant. For similar functionality, evaluate other Melexis pre-drivers like the MLX83203 for different motor types, but verify pinout and feature compatibility carefully.
