Overview
The MLX83100LGO-DBA-000-RE is an automotive-grade two-phase pre-driver IC designed for brushed DC motor applications. It integrates a current sense amplifier and drives four external N-FETs to form a full H-bridge. The device operates within a supply voltage range of 4.5 V to 28 V, utilizing an integrated charge pump for high-side gate drive support. Key electrical parameters include a typical gate drive current of 300 mA, rise and fall times of 7 ns, and power supply voltages between 7 V and 18 V. It accepts 2 or 4 PWM inputs from a microcontroller and features a serial ICOM diagnostics interface for fault reporting.
Feature Summary
- Converts microcontroller PWM inputs to drive four external N-FETs for full H-bridge control
- Integrates a fast, high-bandwidth current sense amplifier for precise torque control
- Includes comprehensive monitoring functions such as undervoltage, overvoltage, and overtemperature detection
- Supports 100% PWM operation via trickle charge pump and bootstrap circuits
Applications
- Automotive brushed DC motor control systems
- Full H-bridge driver configurations using discrete power N-FETs
- Applications requiring precise torque control with integrated current sensing
Procurement Notes
Verify component authenticity through authorized Melexis distributors. Confirm package integrity for the TSSOP-28 format. Check for end-of-life status indicators as some listings suggest obsolescence. Ensure compatibility with required automotive quality standards before integration into final designs.
Selection Notes
Select this component for brushed DC motor applications requiring integrated current sensing and robust protection features. Consider the 28-TSSOP-EP package for thermal management. Evaluate the need for external N-FETs compatible with the 300 mA gate drive capability. Verify that the operating voltage range aligns with the system's 4.5 V to 28 V requirements.
Part Context
This part belongs to the MLX83100 family of automotive pre-drivers. It is distinct from brushless DC controllers like the MLX83203 or embedded MCU solutions in the MLX8120x series. The device serves as a bridge driver interface between microcontrollers and power stages, focusing on brushed DC topology rather than sensorless BLDC control.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Users should consult Melexis technical support for direct replacements or pin-compatible alternatives if this specific suffix is discontinued.
