Monolithic Power Systems Inc. MPM3807CGLE-AEC1-Z

Overview

MPM3807CGLE-AEC1-Z from Monolithic Power Systems is an AEC-Q100 Grade 1 qualified, fully integrated synchronous step-down power module with internal MOSFETs and inductor, delivering up to 2A continuous output current at 2.4MHz switching frequency across a 2.5V–5.5V input range. It features constant-on-time (COT) control, 1% FB accuracy, and power-good signaling-designed for automotive ADAS sensors and camera modules requiring compact, thermally robust DC/DC conversion.

For engineers reviewing the MPM3807CGLE-AEC1-Z datasheet, MPM3807CGLE-AEC1-Z pinout, MPM3807CGLE-AEC1-Z application, or MPM3807CGLE-AEC1-Z equivalent, this module supports adjustable-output configurations with external resistor divider feedback, enables precise power sequencing via EN, provides thermal and short-circuit protection with hiccup mode, and integrates soft-start and output discharge for reliable startup and shutdown behavior in safety-critical automotive systems.

Technical Context

The MPM3807CGLE-AEC1-Z implements input-voltage feed-forward constant-on-time (COT) control with fixed minimum off-time (80ns), enabling fast transient response and stable operation across 2.5V–5.5V VIN and full load range. Its forced continuous conduction mode (FCCM) ensures consistent 2.4MHz switching frequency regardless of load or input variation.

Internally integrated P-channel high-side (70mΩ R_ON) and N-channel low-side (40mΩ R_ON) MOSFETs drive a 470nH inductor with 25mΩ DCR, supporting 100% duty cycle for low-dropout operation. The device uses a 0.6V internal reference and monitors V_FB to regulate output voltage with ±1% accuracy over –40°C to +150°C junction temperature.

FAQ

Is MPM3807CGLE-AEC1-Z pin-compatible with non-AEC versions like MPM3807CGLE-Z?

No. While both share identical pinout and package, the MPM3807CGLE-AEC1-Z undergoes additional automotive qualification testing (AEC-Q100 Grade 1), includes wettable flank plating for solder joint inspection, and has tighter parametric screening across –40°C to +150°C. Substituting non-AEC versions voids automotive compliance.

What is the recommended minimum soft-start capacitor value and how does it affect startup?

The datasheet specifies a minimum 1nF capacitor from SS to GND. With typical 3µA internal charge current, a 1nF cap yields ~0.2ms soft-start time. Larger values increase ramp duration linearly-e.g., 10nF gives ~2ms-reducing inrush but extending power-up latency. Always verify against downstream load hold-up requirements.

Can the FB pin be left floating in adjustable-output configurations?

No. In adjustable-output mode (like MPM3807CGLE-AEC1-Z), the FB pin must be connected to a resistor divider between V_OUT and GND to set output voltage. Floating FB causes unregulated, potentially damaging output voltage. For fixed-output variants (e.g., -12-AEC1), FB is floated per datasheet instructions.

How does the OUT_S pin function during normal operation versus shutdown?

During normal operation, OUT_S serves as a high-impedance sense node for output voltage regulation. During shutdown, it activates an internal 150Ω discharge path to GND, actively bleeding stored energy from the output capacitor-preventing lingering voltage that could disrupt downstream logic or cause latch-up.

Does MPM3807CGLE-AEC1-Z support pre-biased output startup?

Yes. The device initiates soft-start regardless of initial V_OUT voltage-even if pre-charged-and avoids reverse current flow using internal control logic. This enables safe power sequencing in multi-rail systems where other supplies may be active before the MPM3807C enables.

What thermal derating applies above 100°C ambient temperature?

With θ_JA = 65°C/W on standard 4-layer PCB, maximum allowable power dissipation drops linearly: PD_MAX = (150°C − T_A) / 65°C/W. At 100°C ambient, PD_MAX = 0.77W-corresponding to ~1.3A at 1.2V output. Use thermal vias and copper flooding to improve real-world performance beyond JEDEC limits.

Is the PG signal compatible with 1.8V logic systems?

Yes. PG is open-drain and requires an external pull-up. When used with a 1.8V supply and 10kΩ pull-up, PG asserts high at ~1.7V (within 1.8V logic high threshold) and pulls low to <0.4V-fully compliant with 1.8V CMOS input levels. Ensure pull-up resistor value accounts for sink current (1mA max) and rise time requirements.
