Overview
The LM3409QHVMYX/NOPB is an automotive-grade P-FET buck controller designed for high-power LED drivers. It operates with a maximum input voltage of 75V and supports adjustable switch frequencies. The device features precision dimming control, thermal shutdown protection, and enable/shutdown functionality. It is housed in a 10-MSOP-PowerPAD package and functions within a temperature range of -40°C to +125°C. Certified under AEC-Q100 standards, it ensures reliability for demanding automotive lighting applications.
Feature Summary
- Automotive qualification compliant with AEC-Q100 standards for enhanced reliability
- Supports high-side current sensing with P-FET topology for efficient regulation
- Enables precise analog and PWM dimming control for adaptive lighting systems
Applications
- Automotive exterior lighting modules requiring robust voltage handling
- High-power LED headlamp driver circuits
- Adaptive driving beam (ADB) systems
Procurement Notes
Verify the specific suffix 'HV' indicates the 75V input variant distinct from standard 42V versions. Confirm AEC-Q100 certification status matches project requirements. Ensure the MSOP-PowerPAD package compatibility with PCB layout constraints. Cross-reference the exact part number against manufacturer databases to avoid confusion with non-automotive equivalents or different voltage ratings.
Selection Notes
Select this component when designing LED drivers for automotive environments requiring input voltages up to 75V. The HV variant is necessary for systems exceeding 42V input limits. Consider the thermal performance of the PowerPAD package for heat dissipation. Verify that the adjustable frequency range aligns with EMI filtering requirements. Ensure the dimming interface matches the vehicle's control architecture.
Part Context
This part belongs to the LM3409 family of P-FET buck controllers from Texas Instruments. The 'Q' designation signifies automotive qualification, while 'HV' denotes the high-voltage 75V capability. It complements lower-voltage variants like the LM3409MYX/NOPB, which are limited to 42V inputs. The family provides scalable solutions for various LED power levels in automotive lighting.
Replacement Considerations
LM3409HVX/NOPB serves as a direct functional equivalent within the same series. Verify pinout and electrical specifications match before substitution. Non-automotive grades lack AEC-Q100 certification and may not suit automotive applications.
