Monolithic Power Systems Inc. MPM3807CGLE-AEC1-P

Overview

MPM3807CGLE-AEC1-P from Monolithic Power Systems is an AEC-Q100 Grade 1 qualified, fully integrated synchronous step-down power module with embedded MOSFETs and inductor, delivering up to 2A continuous output current at 2.4MHz switching frequency, 1% FB voltage accuracy (0.6V), and -40°C to +150°C junction temperature range. It serves as a compact, high-efficiency DC-DC converter for automotive ADAS sensors and camera modules.

For engineers reviewing the MPM3807CGLE-AEC1-P datasheet, MPM3807CGLE-AEC1-P pinout, MPM3807CGLE-AEC1-P application, or MPM3807CGLE-AEC1-P equivalent, key selection criteria include its wettable-flank QFN-15 package, adjustable-output architecture (FB-based regulation), FCCM operation across full load, and integrated protections including hiccup-mode SCP, thermal shutdown, and output OVP.

Technical Context

The MPM3807CGLE-AEC1-P implements constant-on-time (COT) control with input voltage feed-forward, enabling stable 2.4MHz switching across 2.5V–5.5V input and maintaining fast transient response without external compensation. Its internal 70mΩ/40mΩ PCH/NCH MOSFET pair and 470nH integrated inductor support high efficiency and low thermal rise under 2A load.

It operates in forced continuous conduction mode (FCCM) with 100% duty cycle capability, supports pre-biased start-up, and features dedicated pins for soft-start timing (SS), output sensing (OUT_S), and open-drain power-good indication (PG). The FB pin sets output via external resistor divider (adjustable version), while EN enables precise power sequencing.

Key Specifications

Pinout & Package

MPM3807CGLE-AEC1-P is housed in a thermally enhanced, wettable-flank QFN-15 package (3mm × 4mm × 1.6mm) with exposed thermal pad. Pin 10–11 are GND pads tied directly to the thermal pad for optimal heat dissipation; Pin 15 (DNC) is internally connected to SW and must remain unconnected on PCB.

FAQ

What output voltage options does MPM3807CGLE-AEC1-P support?

MPM3807CGLE-AEC1-P is the adjustable-output variant, configured via external resistor divider on the FB pin to set VOUT from 0.6V up to VIN – 0.5V. Fixed-output versions (e.g., MPM3807CGLE-12-AEC1) offer factory-trimmed 1.2V or 1.8V; this part requires no internal feedback network and achieves ±1% regulation accuracy across temperature.

How does the OUT_S pin function during shutdown?

During shutdown, the OUT_S pin activates an internal 150Ω discharge path between VOUT and GND, rapidly bleeding stored charge from the output capacitor. This prevents residual voltage from interfering with downstream logic states or causing latch-up in powered-off subsystems - critical for automotive functional safety compliance.

Can MPM3807CGLE-AEC1-P operate with a pre-biased output?

Yes - the device supports pre-biased start-up: when EN is asserted, it begins soft-start regardless of initial VOUT voltage. This feature enables hot-swap capability and safe integration into multi-rail power systems where output rails may already be charged by other regulators before enablement.

What is the purpose of the DNC pin (Pin 15)?

Pin 15 is designated "Do Not Connect" and is internally bonded to the SW node. Routing traces or placing vias under this pad introduces parasitic inductance and thermal stress, degrading switching performance and reliability. It must remain unconnected and unmasked in stencil design to prevent solder bridging.

How does the PG pin interface with system logic?

PG is an open-drain output requiring an external pull-up resistor (10kΩ–100kΩ) to a logic-compatible voltage (e.g., 3.3V or 5V). It asserts high when VFB ≥ 90% of 0.6V (≥540mV), indicating valid regulation; pulls low when VFB ≤ 85% (≤510mV), signaling fault. Self-bias behavior occurs if pulled up externally while VIN/EN are inactive.

Is FCCM mode mandatory, or can it be disabled?

FCCM is inherent to the MPM3807C architecture and cannot be disabled. It ensures continuous inductor current across all loads (0–2A), eliminating mode transitions that cause variable-frequency noise and complicating EMI filter design - a deliberate feature for automotive EMC robustness.

What thermal performance can be expected on a standard 4-layer PCB?

On MPS's EVM3807C-LE-00A (6.3cm × 6.3cm, 4-layer, 2oz Cu), θJA is 53°C/W and θJC is 10°C/W. At 2A load and 3.3V input, case temperature rise is ~12°C - confirming suitability for sealed enclosures without forced airflow in automotive interior applications.
