Overview
The MLX83100LGO-DBA-000-SP is an automotive-grade two-phase brushed DC pre-driver IC with an integrated current sense amplifier. Designed for driving four external N-FETs in full H-bridge configurations, it operates within a supply voltage range of 4.5 V to 28 V. The device features a trickle charge pump enabling 100% PWM operation and supports gate charges up to 500 nC per FET at 20 kHz. It includes comprehensive protection mechanisms such as undervoltage, overvoltage, over-temperature detection, and FET monitoring. Fault diagnostics are communicated via a serial ICOM interface using PWM duty cycles.
Feature Summary
- Integrated current sense amplifier for precise torque control
- Trickle charge pump allows 100% pulse width modulation operation
- Serial ICOM diagnostics interface for fault reporting
- Comprehensive monitoring including UV/OV, over-temperature, and FET voltage checks
Applications
- Automotive brushed DC motor control
- Full H-bridge driver circuits
- Systems requiring precise torque regulation
Procurement Notes
Verify the specific suffix 'SP' against official Melexis documentation to confirm package type and tape/reel specifications. Confirm end-of-life status if applicable, as some variants may be obsolete. Ensure compatibility with your microcontroller's logic levels and verify that the 28-TSSOP exposed pad package fits your PCB footprint constraints before ordering.
Selection Notes
Select this component when designing automotive brushed DC motor drives requiring integrated sensing and robust protection. It is suitable for applications needing high-side bootstrap drive with low supply voltage support. Consider the integrated current sense amplifier if external sensing components are to be minimized. Ensure the external N-FET gate charge requirements do not exceed the specified limits for the target PWM frequency.
Part Context
This part belongs to the MLX83100 family of automotive 2-phase brushed DC B4 pre-drivers. It is designed to work in conjunction with a microcontroller and discrete power N-FETs. The family also includes variants like the MLX83100LGO-DCA-000-RE. For brushless DC applications, the MLX83203 or MLX8120x series are recommended alternatives.
Replacement Considerations
Check for direct pin-to-pin replacements within the MLX83100 family, such as the MLX83100LGO-DCA-000-RE, ensuring functional equivalence. Verify if the MLX83100LGO-DBA-000-RE is available if the SP suffix denotes a specific packaging variant. No other cross-family substitutes are confirmed without detailed electrical comparison.
