Monolithic Power Systems Inc. MPM3807GLE-12-AEC1-P

Overview

MPM3807GLE-12-AEC1-P from Monolithic Power Systems is an AEC-Q100 Grade 1 qualified, fully integrated synchronous step-down power module with built-in inductor and MOSFETs, delivering up to 2A continuous output at fixed 1.2V with ±2% regulation accuracy, 2.4MHz switching frequency, and operation across -40°C to +150°C junction temperature. It serves as a compact, high-efficiency DC/DC supply for automotive ADAS sensors and camera modules.

For engineers reviewing the MPM3807GLE-12-AEC1-P datasheet, MPM3807GLE-12-AEC1-P pinout, MPM3807GLE-12-AEC1-P application, or MPM3807GLE-12-AEC1-P equivalent, key selection considerations include its wettable-flank QFN-15 package, 1.2V fixed-output architecture, AEC-Q100 qualification, integrated thermal shutdown and OVP/SCP protection, and compatibility with low-EMI board layouts using MeshConnect™ flip-chip technology.

Technical Context

The MPM3807GLE-12-AEC1-P implements constant-on-time (COT) control with VIN feed-forward to maintain stable 2.4MHz switching across 2.5V–5.5V input range, enabling fast transient response without external compensation. Its internal 70mΩ HS-FET and 40mΩ LS-FET pair with a 470nH integrated inductor to support 2A continuous load with <0.3% load regulation at 2A.

It integrates a dedicated OUT_S pin for output voltage sensing and controlled discharge, a 100%-duty-cycle LDO mode for ultra-low dropout, and Advanced Asynchronous Modulation (AAM) with zero-current detection (50mA threshold) to sustain DCM operation and achieve 21µA quiescent current in sleep mode.

FAQ

What is the purpose of the OUT_S pin on the MPM3807GLE-12-AEC1-P?

The OUT_S pin provides dedicated output voltage sensing for improved regulation accuracy and enables controlled output capacitor discharge during shutdown. Internally, it connects to a 150Ω resistor to GND when the device is disabled, safely bleeding stored charge from the output rail without requiring external circuitry-critical for automotive functional safety compliance.

Does the MPM3807GLE-12-AEC1-P require external compensation components?

No. The MPM3807GLE-12-AEC1-P uses constant-on-time (COT) control with integrated compensation network, eliminating the need for external type-II or type-III compensation networks. This simplifies design, reduces BOM count, and ensures stable operation across all input voltages and load conditions without tuning.

Can the MPM3807GLE-12-AEC1-P operate with input voltage below 2.5V?

No. The device has a hard UVLO threshold of 2.45V (rising) and will not start or regulate below 2.5V input. Attempting to operate below this level results in complete shutdown; it is not designed for sub-2.5V battery backup or supercapacitor hold-up applications.

How does the PG pin behave during power-up and fault conditions?

The PG pin asserts high (open-drain pulled up externally) when VOUT reaches ≥90% of 1.2V (≥1.08V) and remains high until VOUT drops ≤85% (≤1.02V). During overvoltage, short-circuit, or thermal shutdown, PG pulls low within 80µs, providing precise system-level power sequencing and fault indication without additional monitoring circuitry.

Is the 1.2V output voltage adjustable via external resistors?

No. The MPM3807GLE-12-AEC1-P is a fixed-output variant; the "12" suffix denotes factory-trimmed 1.2V regulation. The FB pin must be left floating. For adjustable versions, use MPM3807GLE-AEC1, which requires external resistor divider between OUT and GND to set VOUT.

What thermal derating applies at 105°C ambient temperature?

Using θJA = 65°C/W and TJ(MAX) = 150°C, maximum continuous power dissipation at TA = 105°C is (150 − 105)/65 ≈ 0.69W. At typical 1.2V/2A operation (2.4W output), this implies significant current derating-designers should consult the efficiency vs. load curves and case temperature rise plots to confirm safe operation at target ambient and airflow conditions.

Does the MPM3807GLE-12-AEC1-P support forced PWM mode?

No. It operates exclusively in COT mode with automatic transition between continuous conduction mode (CCM), discontinuous conduction mode (DCM), and sleep mode based on load. There is no pin or register to force fixed-frequency PWM; light-load efficiency is managed via AAM and ZCD instead.
