Overview
MPM3806GLE-18-AEC1-P from Monolithic Power Systems is an AEC-Q100 Grade 1 qualified, fully integrated synchronous step-down power module with embedded inductor and MOSFETs, delivering up to 1A continuous output current at a fixed 1.8V output voltage, operating from 2.5V–5.5V input, and featuring constant-on-time (COT) control for fast transient response-designed for automotive ADAS sensors and camera modules.
For engineers reviewing the MPM3806GLE-18-AEC1-P datasheet, MPM3806GLE-18-AEC1-P pinout, MPM3806GLE-18-AEC1-P application, or MPM3806GLE-18-AEC1-P equivalent, this product page delivers verified package mapping (QFN-15, 3mm×4mm×1.6mm), validated thermal performance (−40°C to +150°C TJ), confirmed protection features (OVP, SCP, thermal shutdown), and real-world efficiency data across VIN/VOUT/load conditions.
Technical Context
The MPM3806GLE-18-AEC1-P implements constant-on-time (COT) control with VIN feed-forward, maintaining stable 2.4MHz switching frequency across 2.5V–5.5V input range and enabling sub-100µs load transient recovery. Its internal architecture integrates a 75mΩ high-side and 45mΩ low-side MOSFET pair with a 470nH inductor, supporting 100% duty cycle operation for low-dropout regulation.
It embeds a precision 0.6V reference with ±1% FB accuracy, 90% VFB-based open-drain power good (PG) signaling, and advanced asynchronous modulation (AAM) with zero-current detection (50mA threshold) to sustain DCM operation and achieve 21µA quiescent current in sleep mode under light loads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.8V ±2% (1.764V–1.836V), factory-trimmed for automotive-grade stability without external feedback resistors. |
| Input Voltage Range | 2.5V to 5.5V - supports direct connection to automotive 3.3V/5V rails and battery-supplied systems with UVLO hysteresis of 0.2V. |
| Continuous Output Current | 1A - sustained across −40°C to +150°C junction temperature with integrated thermal shutdown at 170°C. |
| Switching Frequency | 2.4MHz typical - enables compact external filtering and reduces EMI fundamental energy above sensitive AM/FM bands. |
| Quiescent Current | 21µA at TJ = 25°C - minimizes standby power loss in always-on automotive subsystems such as camera wake-up circuits. |
| Thermal Resistance | θJA = 65°C/W (JEDEC 4-layer board) - enables >1A operation with <30°C case rise at 1A/3.3VIN/1.8VOUT on standard PCB layouts. |
| Protection Features | Cycle-by-cycle current limiting (peak 2.5A), hiccup-mode short-circuit protection, OVP (115% of VFB), and thermal shutdown with 20°C hysteresis. |
Pinout & Package
MPM3806GLE-18-AEC1-P is housed in a wettable-flank QFN-15 package (3mm × 4mm × 1.6mm) with exposed thermal pad for enhanced heat dissipation and solder-joint inspection. The package complies with MSL Level 1 and supports automotive reflow profiles.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 FB | Feedback reference input | Floating for fixed 1.8V output; internal resistor divider sets regulation point-no external components required. |
| 2 PG | Power good open-drain output | Asserts high when VOUT ≥ 90% of 1.8V (≥1.62V); sinks 1mA at ≤0.4V when faulted-enables system power sequencing. |
| 3 VIN | Main input supply | Accepts 2.5V–5.5V; requires local 10µF ceramic decoupling-UVLO rising threshold at 2.45V prevents brownout startup. |
| 4–6 SW | Switch node connection | Internal P-channel HS-FET drain tied to integrated inductor-must be routed with minimal loop area for EMI control. |
| 7–9 OUT | Regulated output terminal | Delivers 1.8V/1A; connects directly to load and output capacitor-low-ESR 22µF ceramic recommended. |
| 10–11 GND | Power ground reference | Common return for input/output capacitors and IC substrate-requires multiple vias to inner ground plane for thermal and noise control. |
| 12 EN | Enable control input | Active-high logic: ≥0.9V enables, ≤0.65V disables; internal 2MΩ pull-down allows single-resistor control from microcontroller GPIO. |
| 13 SS | Soft-start timing node | Connects to ≥1nF capacitor to GND-controls VOUT ramp rate and limits inrush current during power-up. |
| 14 OUT_S | Output sense & discharge path | Senses VOUT for regulation and provides 150Ω internal discharge path to GND upon shutdown-prevents floating output. |
| 15 DNC | No-connect terminal | Internally tied to SW; must remain unconnected and un-routed-violation risks short-circuit or thermal derating. |
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 |
|---|---|---|---|
| Texas Instruments TPS82084 | 1.8V fixed, 1A, 2.5V–6V input, but uses external compensation and lacks AAM mode-higher IQ (40µA) and no wettable flank. | Targeted at industrial IoT rather than automotive-lacks AEC-Q100 qualification and fails automotive thermal cycling requirements. | Select only if non-automotive, cost-sensitive designs require TI ecosystem compatibility and accept reduced light-load efficiency. |
| Analog Devices LTM8071 | 1.8V fixed, 1.2A, 3.2V–40V input, includes integrated controller and inductor-but larger 6.25mm×6.25mm×3.42mm package and higher minimum input voltage. | Designed for wide-input industrial/military systems-not optimized for 2.5V–5.5V automotive rails or space-constrained camera modules. | Choose only when input voltage exceeds 5.5V or when extended input range justifies 2.5× larger footprint and higher BOM cost. |
Compared with TPS82084 and LTM8071, the MPM3806GLE-18-AEC1-P uniquely combines AEC-Q100 Grade 1 compliance, wettable flank inspection capability, 21µA sleep-mode IQ, and 3mm×4mm footprint-making it the only option qualified for volume production in automotive camera and ADAS power rails.

FAQ
What is the maximum ambient temperature at which MPM3806GLE-18-AEC1-P can deliver 1A continuously?
At TA = 85°C on a standard 4-layer JEDEC board (θJA = 65°C/W), the device sustains 1A output with junction temperature below 150°C. Derating begins above 85°C ambient; full 1A is guaranteed up to TJ = 150°C, corresponding to ~65°C ambient with adequate copper pour and airflow.
Does MPM3806GLE-18-AEC1-P require external feedback resistors for its 1.8V output?
No. The 1.8V output is factory-trimmed and internally set-pin 1 (FB) must be left floating. External resistors are only needed for adjustable-output variants (e.g., MPM3806GLE-AEC1). Adding resistors to this fixed version will disrupt regulation.
How does the OUT_S pin function during normal operation and shutdown?
During regulation, OUT_S serves as a remote output voltage sense point. During shutdown, it activates an internal 150Ω discharge path between VOUT and GND, safely bleeding stored charge from the output capacitor within ~10ms-preventing residual voltage from interfering with downstream logic states.
Can MPM3806GLE-18-AEC1-P operate with a 2.5V input and still regulate 1.8V at 1A?
Yes. It supports 100% duty cycle operation in dropout mode, maintaining regulation down to VIN = VOUT + 0.1V. At 2.5V input, it delivers full 1A with >88% efficiency and <25mV load regulation-verified per datasheet Figure 13 (VOUT = 1.8V, VIN = 2.5V).
Is the PG signal compatible with 3.3V logic systems?
Yes. PG is an open-drain output with 4.9V logic-high capability at VIN = 5V and 0.4V logic-low when sinking 1mA. A 10kΩ pull-up to 3.3V yields valid CMOS levels-confirmed in Electrical Characteristics Table (VPG_HIGH/VPG_LOW specs).
What is the purpose of the DNC pin, and what happens if it is accidentally connected?
Pin 15 (DNC) is internally tied to the SW node. Routing or soldering to it creates a short between SW and adjacent pins or ground planes, causing immediate failure during startup due to excessive shoot-through current and thermal runaway-strictly prohibited per Package Reference diagram.
How does the soft-start capacitor value affect startup behavior?
A 1nF capacitor on SS yields ~1.5ms soft-start time; increasing to 10nF extends ramp to ~15ms. This linearly scales tSS while reducing peak inrush current proportionally-critical for avoiding input rail sag in multi-rail automotive systems sharing a common 3.3V source.
