Overview
The MLX83100LGO-DDA-000-SP is an automotive-grade two-phase pre-driver IC designed for brushed DC motor applications. It integrates a current sense amplifier and operates within a supply voltage range of 4.5V to 28V, supporting up to 45V load dump conditions. The device converts PWM inputs from a microcontroller to drive four external N-FETs, providing typical gate drive currents of 300mA. It features a trickle charge pump enabling 100% PWM operation and includes comprehensive protection mechanisms such as undervoltage, overvoltage, and overtemperature detection.
Feature Summary
- Converts microcontroller PWM signals to drive four external N-FETs for full H-bridge control
- Integrates a high-bandwidth, low-offset current sense amplifier for precise torque control
- Includes serial ICOM diagnostics interface for fault reporting via PWM duty cycle
- Features a trickle charge pump allowing 100% pulse width modulation operation
Applications
- Automotive brushed DC motor control
- Window lift actuators
- Seat adjustment systems
- HVAC fan control
Procurement Notes
Verify the specific suffix DDA against the official Melexis datasheet to confirm pinout and configuration options. Ensure the ordering part number matches the required package variant. Confirm AEC-Q100 qualification status for your specific automotive application requirements before finalizing procurement decisions.
Selection Notes
Select this component when designing brushed DC motor drivers requiring integrated current sensing and diagnostic feedback. It is suitable for applications needing robust protection against FET faults and system anomalies. Consider the external N-FET gate charge requirements relative to the 300mA drive capability and bootstrap optimization for your specific PWM frequency.
Part Context
This part belongs to the MLX83100 family of automotive pre-drivers. It serves as a companion to microcontrollers, handling the power stage driving while offloading complex gate drive logic. The family focuses on reliability in harsh automotive environments, offering integrated monitoring that simplifies system design compared to discrete driver solutions.
Replacement Considerations
Consult the MLX83203 for three-phase brushless DC applications within the same pre-driver family. For sensorless BLDC control, consider the MLX8120x embedded MCU series. Direct pin-to-pin replacements should be verified against official cross-reference documents.
