Product details
Overview
MPM6010GQV-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 provides fault indication for LED open/short and thermal shutdown. It is designed for automotive front lighting and interior ambient LED systems.
For engineers reviewing the MPM6010GQV-Z datasheet, MPM6010GQV-Z pinout, MPM6010GQV-Z application, or MPM6010GQV-Z equivalent, key selection criteria include its integrated power stage (85mΩ/50mΩ RDS(ON)), forced CCM operation, 0.2V feedback reference, AEC-Q100 qualification, and QFN-17 wettable flank package compatibility with automated optical inspection (AOI).
Technical Context
The MPM6010GQV-Z uses peak-current-mode control with fixed 2.2MHz switching frequency (foldback to 1.1MHz above ~21V input) and forced continuous conduction mode (CCM) across full load range. Its error amplifier compares FB voltage against a trimmed 0.2V internal reference and drives a compensation network to generate VCOMP, which sets the HS-FET on-time via valley-current detection.
Protection architecture includes cycle-by-cycle over-current protection with valley-current sensing, thermal shutdown at 170°C (30°C hysteresis), UVLO (3.5V rising / 3.1V falling), and open-drain /FAULT reporting for LED short/open and thermal events. The integrated bootstrap regulator maintains ~5V gate drive for the high-side MOSFET using internal charging circuitry.

Pinout & Package
The MPM6010GQV-Z is housed in a space-saving, wettable-flank QFN-17 package (3mm × 5mm × 1.6mm) with exposed thermal pad for enhanced PCB heat dissipation. Pin 17 is NC and must remain unconnected.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 /FAULT | Open-drain fault indicator | Pulled low during LED open/short or thermal shutdown; requires external pull-up (e.g., 100kΩ to VCC) for status monitoring. |
| 2 EN/DIM | Enable/dimming control | Logic-high enables IC; 100Hz–2kHz PWM applied here controls LED brightness; internal 6.5V Zener clamp protects against overvoltage. |
| 3 FB | Current-sense feedback input | Connects to shunt resistor (e.g., 133mΩ for 1.5A); referenced to 0.2V internal precision bandgap. |
| 4 VCC | Internal LDO output | 4.9V regulated supply for internal circuitry; no external capacitor required due to integrated decoupling. |
| 5 AGND | Analog ground reference | Reference node for FB, EN/DIM, and internal analog blocks; internally tied to PGND but kept separate in layout for noise isolation. |
| 6–8, 12 SW | Switch node | High-current connection to internal HS/LS FETs and integrated inductor; requires large copper pour for thermal management and low-inductance routing. |
| 9–11 OUT | LED anode output | Power output to LED+; requires external ceramic output capacitor (e.g., 10µF X7R) for ripple suppression and stability. |
| 13 BST | Bootstrap supply | Internally charged node for high-side gate drive; no external components needed - internal regulator manages BST–SW voltage. |
| 14–15 PGND | Power ground return | Low-impedance return path for switch current; must be connected via multiple vias to inner-layer ground plane. |
| 16 IN | Main input supply | Accepts 4V–36V; requires low-ESR input capacitor (e.g., 4.7µF + 0.1µF) placed adjacent to pin with wide traces. |
| 17 NC | No connection | Unbonded pad; must be left floating - no trace or solder mask should contact this pin. |

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 open/short conditions or thermal shutdown. It must be pulled up externally (e.g., 100kΩ resistor to VCC) to monitor fault status. During normal operation, it remains high-impedance; no active drive is required. This signal enables real-time system diagnostics without additional circuitry.
Can the MPM6010GQV-Z operate below 4V input, and what happens near UVLO threshold?
No - the device disables below 3.2V (UVLO rising threshold) and remains off until VIN exceeds 3.5V. At 3.1V (falling threshold), it shuts down again. Operation below 4V is not supported; attempting to bias EN/DIM externally will not override UVLO. Input must stay within 4V–36V for guaranteed regulation and protection functionality.
How is LED current set, and what tolerance does the 0.2V reference provide?
LED current is set by a single external sense resistor (RFB) connected between FB and LED−, using ILED = 0.2V / RFB. The 0.2V reference has ±4% tolerance over −40°C to +125°C, yielding ≤±4.5% total ILED error with a 1% RFB. No trimming or calibration is needed for automotive-grade accuracy.
Does the MPM6010GQV-Z require an external bootstrap capacitor?
No - the bootstrap capacitor is fully integrated. Pin 13 (BST) connects internally to a dedicated charge pump and regulator that maintains ~5V across BST–SW. External connections to BST are prohibited; adding external capacitance may disrupt internal charging and cause gate-drive failure.
What thermal management practices are recommended for the QFN-17 package?
Use ≥6 thermal vias (0.3mm diameter) under the exposed pad, connected to a solid inner-layer ground plane. Route SW (pins 6–8, 12) and PGND (pins 14–15) with ≥1.2mm copper pours. Avoid placing sensitive traces under the IC. For 1.5A continuous load at 12V input, keep ambient temperature ≤85°C to maintain TJ < 125°C with standard 4-layer board.
Is the MPM6010GQV-Z compatible with PWM dimming frequencies outside the 100Hz–2kHz range?
No - the EN/DIM pin is optimized for 100Hz–2kHz. Frequencies below 100Hz cause visible flicker and may trigger false fault detection; above 2kHz, the internal comparator cannot reliably resolve duty cycles, leading to inconsistent dimming and potential startup issues. Use only within specified range for guaranteed behavior.
How does frequency foldback improve efficiency at high input voltages?
At VIN > ~21V, switching frequency drops from 2.2MHz to 1.1MHz. This reduces gate-drive and switching losses proportionally, improving full-load efficiency by 1.5–2.2% (e.g., from 91.5% to 93.2% at 24V→6V/1.5A). Foldback also occurs during short-circuit and soft-start to limit peak current stress and thermal buildup.
