Monolithic Power Systems Inc. MPM6010GQVE-AEC1-Z

Overview

MPM6010GQVE-AEC1-Z from Monolithic Power Systems is a fully integrated, AEC-Q100 Grade 1 qualified synchronous step-down LED driver module with internal MOSFETs, inductor (2.2µH), and two capacitors. It delivers up to 1.5A continuous LED current across a 4V–36V input range, operates at 2.2MHz (default), supports PWM dimming (100Hz–2kHz), and integrates fault reporting via open-drain /FAULT pin for automotive LED headlamp and DRL applications.

For engineers reviewing the MPM6010GQVE-AEC1-Z datasheet, MPM6010GQVE-AEC1-Z pinout, MPM6010GQVE-AEC1-Z application, or MPM6010GQVE-AEC1-Z equivalent, key selection criteria include its wettable flank QFN-17 package for automated optical inspection, valley-current-based OCP with 2.5A–5.5A limit, 0.2V feedback reference, forced CCM operation, and CISPR25 Class 5 EMI compliance with external filters.

Technical Context

The MPM6010GQVE-AEC1-Z employs fixed-frequency peak-current-mode control with internal 0.2V reference and error amplifier driving COMP voltage to regulate LED current. Its valley-current detection enables robust over-current protection during short-circuit or overload events, while frequency foldback (to 1.1MHz above ~21V VIN) maintains stability under high-input conditions.

It integrates a 4.9V internal LDO (VCC) with no external capacitor required, bootstrap charging circuitry for high-side gate drive, and thermal shutdown with 170°C trip and 30°C hysteresis. The device operates exclusively in forced continuous conduction mode (CCM), eliminating mode transitions and ensuring consistent EMI profile and low output ripple across 0–100% load.

Key Specifications

Pinout & Package

MPM6010GQVE-AEC1-Z uses a wettable flank QFN-17 package (3mm × 5mm × 1.6mm) with exposed thermal pad for enhanced heat dissipation in space-constrained automotive PCBs. The wettable flank enables reliable solder joint inspection via AOI.

FAQ

What is the purpose of the /FAULT pin, and how should it be interfaced?

The /FAULT pin is an open-drain output that pulls low during LED short, LED open, or thermal shutdown events. It must be pulled up externally-typically with a 100kΩ resistor to VCC-to generate a logic-high signal during normal operation. This allows microcontrollers or system monitors to detect faults without additional level-shifting circuitry, and supports direct connection to automotive diagnostic gateways for DTC reporting.

Can the MPM6010GQVE-AEC1-Z operate with input voltages below 4V?

No-the absolute minimum operating input voltage is 4V per the Recommended Operating Conditions table. Below this threshold, the internal UVLO circuit disables the device, and the internal 4.9V LDO cannot sustain regulation. Attempting to operate below 4V may result in erratic behavior or failure to start; cold-crank scenarios must ensure VIN remains ≥4V throughout the event.

How is LED current accuracy affected by temperature and component tolerance?

LED current accuracy depends on the 0.2V internal reference (±4% over -40°C to +125°C) and the tolerance of the external R_FB. With a 1% R_FB, total I_LED error is typically ±5% across temperature. The integrated inductor's DCR drift and MOSFET R_DS(on) variation contribute minimally, as current regulation occurs solely at the FB node-not through sense-resistor or inductor DCR methods.

Does the MPM6010GQVE-AEC1-Z require an external bootstrap capacitor?

No-bootstrap capacitance and charging circuitry are fully integrated. The BST pin connects internally to a dedicated regulator that maintains ~5V across the bootstrap node relative to SW. No external capacitor, diode, or resistor is needed, simplifying layout and eliminating a common point of failure in discrete high-side gate drivers.

What PCB layout practices are critical for thermal performance?

Thermal performance relies on connecting the exposed thermal pad (under the QFN body) to a large internal ground plane using ≥6 thermal vias (0.3mm diameter), and maximizing copper area on pins 6–8 (SW) and 14–15 (PGND). The IN and OUT traces must be wide (>1mm) and short, with input/output capacitors placed within 3mm of their respective pins to minimize parasitic inductance and switching losses.

Is frequency foldback active during PWM dimming?

Yes-frequency foldback activates whenever the input voltage exceeds ~21V, regardless of dimming state. It also engages during soft-start and short-circuit conditions. During 100Hz–2kHz PWM dimming, foldback remains active if VIN >21V, reducing switching frequency to 1.1MHz to maintain gate drive margin and prevent thermal runaway under high-VIN, high-duty-cycle conditions.

How does the valley-current OCP differ from cycle-by-cycle peak-current limiting?

Valley-current OCP monitors inductor current at the end of each switching cycle. If the valley current exceeds a threshold (e.g., during sustained overload), the high-side FET is inhibited-even if the clock pulses-until current falls below the limit. This prevents current runaway during LED shorts while maintaining regulation during transient overloads, unlike pure peak limiting which may allow excessive RMS current buildup.
