Monolithic Power Systems Inc. MPM6010GQV-P

Overview

MPM6010GQV-P 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 features fault indication for LED open/short and thermal shutdown. It is designed for automotive front lighting and daytime running lights.

For engineers reviewing the MPM6010GQV-P datasheet, MPM6010GQV-P pinout, MPM6010GQV-P application, or MPM6010GQV-P equivalent, key selection considerations include its integrated power stage, forced CCM operation for stable frequency across load, 0.2V feedback reference for precise current regulation, and wettable flank QFN-17 package for automated optical inspection in automotive production.

Technical Context

The MPM6010GQV-P uses peak-current-mode control with an internal 0.2V reference and error amplifier driving a COMP node to regulate LED current via external R_FB. Its fixed-frequency architecture (2.2MHz nominal, folds back to 1.1MHz above ~21V) ensures predictable EMI behavior and enables compact passive filtering.

It implements valley-current detection for over-current protection, thermal shutdown at 170°C (with 30°C hysteresis), and an open-drain /FAULT output that asserts low on LED open/short or die overtemperature. The integrated bootstrap regulator maintains gate drive for the high-side MOSFET without external components.

FAQ

What is the minimum input voltage required for MPM6010GQV-P startup?

The MPM6010GQV-P has an under-voltage lockout (UVLO) with a rising threshold of 3.5V (±0.3V). It will not initiate soft-start until VIN exceeds this level. Once operational, it sustains regulation down to 4V, making it compatible with automotive cold-crank conditions where battery voltage may dip to 4.5V.

Can MPM6010GQV-P drive more than two series-connected LEDs?

Yes - the device regulates LED current, not voltage. With sufficient input-to-output headroom (VIN > V_{LED_TOTAL} + V_dropout), it can drive any number of series LEDs. For example, at VIN = 12V and typical 3.2V/LED forward voltage, up to three 3.2V LEDs (9.6V total) are supported with margin for dropout and ripple.

How does the /FAULT pin behave during normal operation?

During normal operation, /FAULT remains in a high-impedance (open-drain) state and must be pulled up externally (e.g., with a 100kΩ resistor to VCC). It only pulls low when detecting LED open circuit, LED short circuit, or die temperature exceeding 170°C - providing unambiguous fault status without active-low logic inversion.

Is an external bootstrap capacitor required for MPM6010GQV-P?

No - the MPM6010GQV-P integrates a bootstrap capacitor and dedicated charging circuit. The BST pin is internally connected and requires no external components. This eliminates a common failure point and simplifies layout compared to controllers requiring external bootstrap networks.

What is the recommended R_FB value for 1.5A LED current?

Per the datasheet, a 133mΩ (1%) resistor sets 1.5A output current, calculated as R_FB = 0.2V / 1.5A. This value is validated for production use and ensures optimal accuracy and thermal performance; deviation beyond ±1% tolerance may impact current regulation precision.

Does MPM6010GQV-P support analog dimming?

No - the MPM6010GQV-P supports only PWM dimming via the EN/DIM pin (100Hz–2kHz). Analog dimming (e.g., variable DC voltage on FB) is not supported; attempting it disrupts the internal current regulation loop and may cause instability or inaccurate output.

What thermal derating applies above 85°C ambient?

The device is rated for junction temperatures up to 125°C (AEC-Q100 Grade 1). Derating is governed by θ_JA = 46°C/W. At 85°C ambient, maximum allowable power dissipation drops to ~1.4W (vs. 2.7W at 25°C), limiting sustained 1.5A output in poorly ventilated enclosures without thermal enhancement.
