Product details
Overview
MPM3807GLE-18-AEC1-Z 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 current at a fixed 1.8V output, operating from 2.5V–5.5V input, and featuring constant-on-time (COT) control for fast transient response in automotive ADAS and infotainment systems.
For engineers reviewing the MPM3807GLE-18-AEC1-Z datasheet, MPM3807GLE-18-AEC1-Z pinout, MPM3807GLE-18-AEC1-Z application, or MPM3807GLE-18-AEC1-Z equivalent, key selection criteria include its wettable-flank QFN-15 package, 1.8V ±1.2% output accuracy over –40°C to +150°C, 2.4MHz switching frequency, integrated 70mΩ/40mΩ MOSFETs, and automotive-grade fault protections including OVP, SCP, thermal shutdown, and PG monitoring.
Technical Context
The MPM3807GLE-18-AEC1-Z implements VIN feed-forward constant-on-time (COT) control to maintain stable 2.4MHz switching across 2.5V–5.5V input and full load range, enabling fast line/load transient response without external compensation. Its internal 470nH inductor and matched high-side (70mΩ) and low-side (40mΩ) MOSFETs are co-optimized for minimal conduction loss and thermal rise under 2A DC load.
It integrates advanced light-load management via Advanced Asynchronous Modulation (AAM) and zero-current detection (ZCD), achieving 21µA quiescent current in sleep mode while sustaining regulation down to near-zero load. The fixed 1.8V output version eliminates external feedback resistors-FB is floated-and uses internal resistor dividers (RBOT = 150kΩ) per functional block diagram.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output voltage | Fixed 1.8V ±1.2% (1.764V–1.836V) over –40°C to +150°C junction temperature |
| Max output current | 2A continuous DC load capability with integrated 470nH inductor and thermal design validated to 150°C TJ |
| Input voltage range | 2.5V to 5.5V - supports direct connection to automotive 3.3V/5V rails and battery-supervised systems |
| Switching frequency | 2.4MHz nominal - enables compact external filtering and reduces EMI fundamental energy above AM band |
| Feedback accuracy | 1% total output regulation error (including temp, line, load, and initial tolerance) for precise SoC core supply |
| Quiescent current | 21µA in sleep mode - extends battery runtime in always-on automotive modules like V2X transceivers |
| Thermal protection | 170°C junction thermal shutdown with 20°C hysteresis - prevents permanent damage during sustained overload |
| Power good threshold | PG asserts when VOUT ≥ 90% of 1.8V (≥1.62V); deasserts at ≤85% (≤1.53V) - provides reliable system power sequencing signal |
Pinout & Package
MPM3807GLE-18-AEC1-Z is housed in a wettable-flank QFN-15 package (3mm × 4mm × 1.6mm) with exposed thermal pad, optimized for automated optical inspection (AOI) and enhanced solder joint reliability in automotive reflow processes.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 FB | Feedback reference input | Floated in fixed 1.8V version; internal divider sets regulation point - no external resistors required |
| 2 PG | Open-drain power-good indicator | Signals valid output (≥1.62V); requires external pull-up for host MCU reset or enable sequencing |
| 3 VIN | Main input supply | Accepts 2.5V–5.5V; decoupling capacitor mandatory at pin for stability and EMI suppression |
| 4–6 SW | Switch node | Internal connection to high-side P-MOSFET drain and integrated inductor - must be routed with low-inductance path |
| 7–9 OUT | Regulated output | Delivers 1.8V/2A; connects directly to load and output capacitor - multiple pins reduce IR drop and improve thermal spreading |
| 10–11 GND | Power ground | Low-impedance return for input/output caps and IC core; requires large copper pour and multiple vias to internal ground plane |
| 12 EN | Enable control | Logic-compatible input: >0.9V = on, <0.65V = off; internal 2MΩ pull-down enables default-off safety behavior |
| 13 SS | Soft-start timing | Connects to GND via capacitor (min 1nF) to linearly ramp output voltage and limit inrush current during startup |
| 14 OUT_S | Output sense & discharge | Provides VOUT sensing path and activates internal 150Ω discharge FET when EN = low - ensures rapid output collapse |
| 15 DNC | No-connect | Internally tied to SW; must remain unconnected and un-routed - avoids parasitic coupling or short circuits |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous step-down power module applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS82084SILR | 1.8V fixed, 2A, 2.2MHz, QFN-12 (2.5mm×3mm), no wettable flanks, 30µA IQ | Lacks AEC-Q100 qualification and automotive thermal rating (TJ max = 125°C) | Select only for non-automotive industrial or consumer use where qualification and extended temperature are not required. |
| RT7297BZQW | 1.8V fixed, 2A, 2.5MHz, QFN-16 (3mm×3mm), AEC-Q100 Grade 2 (–40°C to +105°C), 25µA IQ | Lower max junction temperature rating and no integrated inductor - requires external magnetics and compensation | Choose when board space allows discrete inductor placement and Grade 2 qualification suffices for cabin applications. |
Compared with TPS82084SILR and RT7297BZQW, the MPM3807GLE-18-AEC1-Z uniquely combines AEC-Q100 Grade 1 qualification, wettable-flank packaging, integrated inductor, and 150°C junction rating - making it the only option qualified for under-hood ADAS sensor power delivery with zero external magnetics.

FAQ
What is the maximum allowable input voltage for MPM3807GLE-18-AEC1-Z?
The absolute maximum input voltage is +6.5V across all pins, but the recommended operating range is strictly 2.5V to 5.5V. Exceeding 5.5V risks triggering the 6.15V VIN over-voltage protection (OVP), causing immediate shutdown. Sustained operation above 5.5V may degrade reliability or violate AEC-Q100 stress limits.
Does MPM3807GLE-18-AEC1-Z require external compensation components?
No. The device integrates a complete compensation network - including EA resistor (25kΩ) and capacitor (25pF) - optimized for its internal 470nH inductor and MOSFETs. No external compensation is needed for stable operation across the full 0–2A load range and 2.5V–5.5V input range.
How does the power-good (PG) signal behave during startup and fault conditions?
PG asserts high (open-drain pulled up externally) when VOUT reaches ≥90% of 1.8V (≥1.62V) and remains asserted until VOUT drops below 85% (≤1.53V). During short-circuit or thermal shutdown, PG deasserts within 80µs and stays low until recovery - providing deterministic sequencing and fault indication to host controllers.
Can MPM3807GLE-18-AEC1-Z operate with 100% duty cycle? Under what conditions?
Yes. It supports 100% duty cycle in low-dropout mode when VIN is within ~100mV of VOUT (e.g., VIN = 1.9V, VOUT = 1.8V). This occurs automatically when the COT controller cannot achieve regulation with finite tON - enabling operation during automotive cold-crank or brownout events without dropout.
What is the purpose of the OUT_S pin, and how should it be connected?
OUT_S serves dual functions: (1) precision output voltage sensing for feedback loop accuracy, and (2) activation of the internal 150Ω discharge FET when EN is low. It must be connected directly to the output capacitor's positive terminal - no series resistance or filtering - to ensure accurate regulation and effective output discharge.
Is the MPM3807GLE-18-AEC1-Z compatible with standard lead-free reflow profiles?
Yes. It is rated for JEDEC J-STD-020 moisture sensitivity level (MSL) 1 and supports peak reflow temperatures up to 260°C. The wettable flank structure is compatible with standard Type 3 and Type 4 solder pastes and has been validated across industry-standard reflow profiles including IPC-7530.
How does the device manage efficiency at light loads?
It employs Advanced Asynchronous Modulation (AAM) and zero-current detection (ZCD) to enter discontinuous conduction mode (DCM) under light loads, reducing switching losses. Combined with sleep mode (21µA IQ), this achieves >85% efficiency at 1mA load with 3.3V input and 1.8V output - critical for always-on automotive subsystems.
