Monolithic Power Systems Inc. MPM6010GQV-AEC1-P

Overview

MPM6010GQV-AEC1-P from Monolithic Power Systems is an AEC-Q100 Grade 1 qualified, synchronous step-down LED driver module integrating power MOSFETs, a 2.2µH inductor, and two capacitors in a single QFN-17 (3mm×5mm×1.6mm) package. It delivers up to 1.5A continuous LED current with 4V–36V input range, 2.2MHz fixed switching frequency, and 0.2V feedback reference for precise current regulation - deployed in automotive front lighting and daytime running lamps.

For engineers reviewing the MPM6010GQV-AEC1-P datasheet, MPM6010GQV-AEC1-P pinout, MPM6010GQV-AEC1-P application, or MPM6010GQV-AEC1-P equivalent, key selection considerations include its integrated inductor architecture, valley-current OCP with thermal shutdown, PWM dimming support (100Hz–2kHz), fault-indicating open-drain /FAULT pin, and AEC-Q100 Grade 1 qualification for under-hood automotive environments.

Technical Context

The MPM6010GQV-AEC1-P operates in forced continuous conduction mode (CCM) with peak-current-mode control and internal 0.2V reference, enabling stable LED current regulation across line and load variations. Its integrated bootstrap regulator maintains floating gate drive for the high-side MOSFET, with UVLO (3.5V rising, 3.1V falling) and frequency foldback (to 1.1MHz above ~21V VIN) for robust operation.

It features cycle-by-cycle over-current protection using valley-current detection, thermal shutdown at 170°C (with 30°C hysteresis), and fault reporting via open-drain /FAULT pin pulled low on LED short/open or thermal event. The EN/DIM pin serves dual function: logic enable and PWM dimming input with 1.45V rising/1.0V falling thresholds.

Key Specifications

Pinout & Package

MPM6010GQV-AEC1-P is housed in a wettable-flank QFN-17 package (3mm × 5mm × 1.6mm) with exposed thermal pad for enhanced PCB heat dissipation. Pin 17 is NC (no connection); pins 6–8 and 14–15 are paralleled SW and PGND terminals respectively to reduce impedance and improve thermal performance.

FAQ

What is the maximum allowable input voltage for continuous operation?

The MPM6010GQV-AEC1-P supports continuous operation up to 36V input, with absolute maximum rating of 40V. It is specifically designed to withstand automotive load-dump transients (ISO 7637-2 Pulse 5a) when paired with appropriate input clamping or TVS protection.

How is LED current accuracy affected by temperature?

Feedback reference voltage varies from 184mV to 216mV over −40°C to +125°C junction temperature, resulting in ±8% I_LED variation. Using a 1% tolerance R_FB resistor limits total current error to ±9% across full automotive temperature range.

Can the MPM6010GQV-AEC1-P drive more than two series LEDs?

Yes - it supports up to 4-series white LEDs (≈12V V_F) at 1.5A when VIN ≥ 16V. Output voltage headroom is VIN − V_OUT ≥ 2V for stable regulation; minimum input must exceed total LED forward voltage plus dropout margin.

Is an external bootstrap capacitor required?

No - the MPM6010GQV-AEC1-P integrates both the bootstrap capacitor and charging regulator. External connections to BST are prohibited; the internal 5V bootstrap supply ensures reliable high-side gate drive without layout sensitivity.

What PCB layout practices are critical for thermal performance?

Use ≥4 thermal vias (0.3mm diameter) under the exposed pad, connect to inner-layer solid copper pour, and minimize trace length between IN and PGND. Pins 6–8 (SW) and 14–15 (PGND) must be routed with ≥0.5mm wide copper to limit temperature rise to <25°C at 1.5A full load.

Does the /FAULT pin require a pull-up resistor?

Yes - /FAULT is open-drain and must be pulled up to VCC (or another 3.3V–5V rail) via 10kΩ–100kΩ resistor. Without pull-up, fault condition cannot be detected; typical value is 47kΩ to balance leakage current (<1μA) and rise time (<100ns).

How does frequency foldback improve reliability?

When VIN exceeds ~21V, switching frequency drops from 2.2MHz to 1.1MHz - reducing switching losses and core losses in the integrated inductor. This lowers die temperature by up to 15°C during sustained high-input conditions like alternator overvoltage.
